This version of the library supports only one compression method (deflation) but other algorithms will be added later and will have the same stream interface. Compression can be done in a single step if the buffers are large enough (for example if an input file is mmap'ed), or can be done by repeated calls of the compression function. In the latter case, the application must provide more input and/or consume the output (providing more output space) before each call. The compressed data format used by default by the in-memory functions is the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped around a deflate stream, which is itself documented in RFC 1951. The library also supports reading and writing files in gzip (.gz) format with an interface similar to that of stdio using the functions that start with "gz". The gzip format is different from the zlib format. gzip is a gzip wrapper, documented in RFC 1952, wrapped around a deflate stream. This library can optionally read and write gzip streams in memory as well. The zlib format was designed to be compact and fast for use in memory and on communications channels. The gzip format was designed for single- file compression on file systems, has a larger header than zlib to maintain directory information, and uses a different, slower check method than zlib. The library does not install any signal handler. The decoder checks the consistency of the compressed data, so the library should never crash even in case of corrupted input. */ typedef voidpf (*alloc_func) OF((voidpf opaque, uInt items, uInt size)); typedef void (*free_func) OF((voidpf opaque, voidpf address)); struct internal_state; typedef struct z_stream_s { Bytef *next_in; /* next input byte */ uInt avail_in; /* number of bytes available at next_in */ uLong total_in; /* total nb of input bytes read so far */ Bytef *next_out; /* next output byte should be put there */ uInt avail_out; /* remaining free space at next_out */ uLong total_out; /* total nb of bytes output so far */ char *msg; /* last error message, NULL if no error */ struct internal_state FAR *state; /* not visible by applications */ alloc_func zalloc; /* used to allocate the internal state */ free_func zfree; /* used to free the internal state */ voidpf opaque; /* private data object passed to zalloc and zfree */ int data_type; /* best guess about the data type: binary or text */ uLong adler; /* adler32 value of the uncompressed data */ uLong reserved; /* reserved for future use */ } z_stream; typedef z_stream FAR *z_streamp; /* gzip header information passed to and from zlib routines.

It may introduce some output latency (reading input without producing any output) except when forced to flush. The detailed semantics are as follows. deflate performs one or both of the following actions: - Compress more input starting at next_in and update next_in and avail_in accordingly. If not all input can be processed (because there is not enough room in the output buffer), next_in and avail_in are updated and processing will resume at this point for the next call of deflate(). - Provide more output starting at next_out and update next_out and avail_out accordingly. This action is forced if the parameter flush is non zero. Forcing flush frequently degrades the compression ratio, so this parameter should be set only when necessary (in interactive applications). Some output may be provided even if flush is not set. Before the call of deflate(), the application should ensure that at least one of the actions is possible, by providing more input and/or consuming more output, and updating avail_in or avail_out accordingly; avail_out should never be zero before the call. The application can consume the compressed output when it wants, for example when the output buffer is full (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK and with zero avail_out, it must be called again after making room in the output buffer because there might be more output pending. Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to decide how much data to accumualte before producing output, in order to maximize compression. If the parameter flush is set to Z_SYNC_FLUSH, all pending output is flushed to the output buffer and the output is aligned on a byte boundary, so that the decompressor can get all input data available so far. (In particular avail_in is zero after the call if enough output space has been provided before the call.) Flushing may degrade compression for some compression algorithms and so it should be used only when necessary. If flush is set to Z_FULL_FLUSH, all output is flushed as with Z_SYNC_FLUSH, and the compression state is reset so that decompression can restart from this point if previous compressed data has been damaged or if random access is desired. Using Z_FULL_FLUSH too often can seriously degrade compression. If deflate returns with avail_out == 0, this function must be called again with the same value of the flush parameter and more output space (updated avail_out), until the flush is complete (deflate returns with non-zero avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that avail_out is greater than six to avoid repeated flush markers due to avail_out == 0 on return. If the parameter flush is set to Z_FINISH, pending input is processed, pending output is flushed and deflate returns with Z_STREAM_END if there was enough output space; if deflate returns with Z_OK, this function must be called again with Z_FINISH and more output space (updated avail_out) but no more input data, until it returns with Z_STREAM_END or an error. After deflate has returned Z_STREAM_END, the only possible operations on the stream are deflateReset or deflateEnd. Z_FINISH can be used immediately after deflateInit if all the compression is to be done in a single step. In this case, avail_out must be at least the value returned by deflateBound (see below). If deflate does not return Z_STREAM_END, then it must be called again as described above. deflate() sets strm->adler to the adler32 checksum of all input read so far (that is, total_in bytes). deflate() may update strm->data_type if it can make a good guess about the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered binary. This field is only for information purposes and does not affect the compression algorithm in any manner. deflate() returns Z_OK if some progress has been made (more input processed or more output produced), Z_STREAM_END if all input has been consumed and all output has been produced (only when flush is set to Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not fatal, and deflate() can be called again with more input and more output space to continue compressing. */ ZEXTERN int ZEXPORT deflateEnd OF((z_streamp strm)); /* All dynamically allocated data structures for this stream are freed. This function discards any unprocessed input and does not flush any pending output. deflateEnd returns Z_OK if success, Z_STREAM_ERROR if the stream state was inconsistent, Z_DATA_ERROR if the stream was freed prematurely (some input or output was discarded).

If zalloc and zfree are set to Z_NULL, inflateInit updates them to use default allocation functions. inflateInit returns Z_OK if success, Z_MEM_ERROR if there was not enough memory, Z_VERSION_ERROR if the zlib library version is incompatible with the version assumed by the caller. msg is set to null if there is no error message. inflateInit does not perform any decompression apart from reading the zlib header if present: this will be done by inflate(). (So next_in and avail_in may be modified, but next_out and avail_out are unchanged.) */ ZEXTERN int ZEXPORT inflate OF((z_streamp strm, int flush)); /* inflate decompresses as much data as possible, and stops when the input buffer becomes empty or the output buffer becomes full. It may introduce some output latency (reading input without producing any output) except when forced to flush. The detailed semantics are as follows. inflate performs one or both of the following actions: - Decompress more input starting at next_in and update next_in and avail_in accordingly. If not all input can be processed (because there is not enough room in the output buffer), next_in is updated and processing will resume at this point for the next call of inflate(). - Provide more output starting at next_out and update next_out and avail_out accordingly. inflate() provides as much output as possible, until there is no more input data or no more space in the output buffer (see below about the flush parameter). Before the call of inflate(), the application should ensure that at least one of the actions is possible, by providing more input and/or consuming more output, and updating the next_* and avail_* values accordingly. The application can consume the uncompressed output when it wants, for example when the output buffer is full (avail_out == 0), or after each call of inflate(). If inflate returns Z_OK and with zero avail_out, it must be called again after making room in the output buffer because there might be more output pending. The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much output as possible to the output buffer. Z_BLOCK requests that inflate() stop if and when it gets to the next deflate block boundary. When decoding the zlib or gzip format, this will cause inflate() to return immediately after the header and before the first block. When doing a raw inflate, inflate() will go ahead and process the first block, and will return when it gets to the end of that block, or when it runs out of data. The Z_BLOCK option assists in appending to or combining deflate streams. Also to assist in this, on return inflate() will set strm->data_type to the number of unused bits in the last byte taken from strm->next_in, plus 64 if inflate() is currently decoding the last block in the deflate stream, plus 128 if inflate() returned immediately after decoding an end-of-block code or decoding the complete header up to just before the first byte of the deflate stream. The end-of-block will not be indicated until all of the uncompressed data from that block has been written to strm->next_out. The number of unused bits may in general be greater than seven, except when bit 7 of data_type is set, in which case the number of unused bits will be less than eight. inflate() should normally be called until it returns Z_STREAM_END or an error. However if all decompression is to be performed in a single step (a single call of inflate), the parameter flush should be set to Z_FINISH. In this case all pending input is processed and all pending output is flushed; avail_out must be large enough to hold all the uncompressed data. (The size of the uncompressed data may have been saved by the compressor for this purpose.) The next operation on this stream must be inflateEnd to deallocate the decompression state. The use of Z_FINISH is never required, but can be used to inform inflate that a faster approach may be used for the single inflate() call. In this implementation, inflate() always flushes as much output as possible to the output buffer, and always uses the faster approach on the first call. So the only effect of the flush parameter in this implementation is on the return value of inflate(), as noted below, or when it returns early because Z_BLOCK is used. If a preset dictionary is needed after this call (see inflateSetDictionary below), inflate sets strm->adler to the adler32 checksum of the dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise it sets strm->adler to the adler32 checksum of all output produced so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described below. At the end of the stream, inflate() checks that its computed adler32 checksum is equal to that saved by the compressor and returns Z_STREAM_END only if the checksum is correct. inflate() will decompress and check either zlib-wrapped or gzip-wrapped deflate data. The header type is detected automatically. Any information contained in the gzip header is not retained, so applications that need that information should instead use raw inflate, see inflateInit2() below, or inflateBack() and perform their own processing of the gzip header and trailer. inflate() returns Z_OK if some progress has been made (more input processed or more output produced), Z_STREAM_END if the end of the compressed data has been reached and all uncompressed output has been produced, Z_NEED_DICT if a preset dictionary is needed at this point, Z_DATA_ERROR if the input data was corrupted (input stream not conforming to the zlib format or incorrect check value), Z_STREAM_ERROR if the stream structure was inconsistent (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR if no progress is possible or if there was not enough room in the output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and inflate() can be called again with more input and more output space to continue decompressing. If Z_DATA_ERROR is returned, the application may then call inflateSync() to look for a good compression block if a partial recovery of the data is desired. */ ZEXTERN int ZEXPORT inflateEnd OF((z_streamp strm)); /* All dynamically allocated data structures for this stream are freed.

The fields next_in, zalloc, zfree and opaque must be initialized before by the caller. The method parameter is the compression method. It must be Z_DEFLATED in this version of the library. The windowBits parameter is the base two logarithm of the window size (the size of the history buffer). It should be in the range 8..15 for this version of the library. Larger values of this parameter result in better compression at the expense of memory usage. The default value is 15 if deflateInit is used instead. windowBits can also be -8..-15 for raw deflate. In this case, -windowBits determines the window size. deflate() will then generate raw deflate data with no zlib header or trailer, and will not compute an adler32 check value. windowBits can also be greater than 15 for optional gzip encoding. Add 16 to windowBits to write a simple gzip header and trailer around the compressed data instead of a zlib wrapper. The gzip header will have no file name, no extra data, no comment, no modification time (set to zero), no header crc, and the operating system will be set to 255 (unknown). If a gzip stream is being written, strm->adler is a crc32 instead of an adler32. The memLevel parameter specifies how much memory should be allocated for the internal compression state. memLevel=1 uses minimum memory but is slow and reduces compression ratio; memLevel=9 uses maximum memory for optimal speed. The default value is 8. See zconf.h for total memory usage as a function of windowBits and memLevel. The strategy parameter is used to tune the compression algorithm. Use the value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no string match), or Z_RLE to limit match distances to one (run-length encoding). Filtered data consists mostly of small values with a somewhat random distribution. In this case, the compression algorithm is tuned to compress them better. The effect of Z_FILTERED is to force more Huffman coding and less string matching; it is somewhat intermediate between Z_DEFAULT and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The strategy parameter only affects the compression ratio but not the correctness of the compressed output even if it is not set appropriately. Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler decoder for special applications. deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough memory, Z_STREAM_ERROR if a parameter is invalid (such as an invalid method). msg is set to null if there is no error message. deflateInit2 does not perform any compression: this will be done by deflate(). */ ZEXTERN int ZEXPORT deflateSetDictionary OF((z_streamp strm, const Bytef *dictionary, uInt dictLength)); /* Initializes the compression dictionary from the given byte sequence without producing any compressed output. This function must be called immediately after deflateInit, deflateInit2 or deflateReset, before any call of deflate. The compressor and decompressor must use exactly the same dictionary (see inflateSetDictionary). The dictionary should consist of strings (byte sequences) that are likely to be encountered later in the data to be compressed, with the most commonly used strings preferably put towards the end of the dictionary. Using a dictionary is most useful when the data to be compressed is short and can be predicted with good accuracy; the data can then be compressed better than with the default empty dictionary. Depending on the size of the compression data structures selected by deflateInit or deflateInit2, a part of the dictionary may in effect be discarded, for example if the dictionary is larger than the window size in deflate or deflate2. Thus the strings most likely to be useful should be put at the end of the dictionary, not at the front. In addition, the current implementation of deflate will use at most the window size minus 262 bytes of the provided dictionary. Upon return of this function, strm->adler is set to the adler32 value of the dictionary; the decompressor may later use this value to determine which dictionary has been used by the compressor.

The fields next_in, avail_in, zalloc, zfree and opaque must be initialized before by the caller. The windowBits parameter is the base two logarithm of the maximum window size (the size of the history buffer). It should be in the range 8..15 for this version of the library. The default value is 15 if inflateInit is used instead. windowBits must be greater than or equal to the windowBits value provided to deflateInit2() while compressing, or it must be equal to 15 if deflateInit2() was not used. If a compressed stream with a larger window size is given as input, inflate() will return with the error code Z_DATA_ERROR instead of trying to allocate a larger window. windowBits can also be -8..-15 for raw inflate. In this case, -windowBits determines the window size. inflate() will then process raw deflate data, not looking for a zlib or gzip header, not generating a check value, and not looking for any check values for comparison at the end of the stream. This is for use with other formats that use the deflate compressed data format such as zip. Those formats provide their own check values. If a custom format is developed using the raw deflate format for compressed data, it is recommended that a check value such as an adler32 or a crc32 be applied to the uncompressed data as is done in the zlib, gzip, and zip formats. For most applications, the zlib format should be used as is. Note that comments above on the use in deflateInit2() applies to the magnitude of windowBits. windowBits can also be greater than 15 for optional gzip decoding. Add 32 to windowBits to enable zlib and gzip decoding with automatic header detection, or add 16 to decode only the gzip format (the zlib format will return a Z_DATA_ERROR).

If a zlib stream is being decoded, then head->done is set to -1 to indicate that there will be no gzip header information forthcoming. Note that Z_BLOCK can be used to force inflate() to return immediately after header processing is complete and before any actual data is decompressed. The text, time, xflags, and os fields are filled in with the gzip header contents. hcrc is set to true if there is a header CRC. (The header CRC was valid if done is set to one.) If extra is not Z_NULL, then extra_max contains the maximum number of bytes to write to extra. Once done is true, extra_len contains the actual extra field length, and extra contains the extra field, or that field truncated if extra_max is less than extra_len.

If comment is not Z_NULL, then up to comm_max characters are written there, terminated with a zero unless the length is greater than comm_max. When any of extra, name, or comment are not Z_NULL and the respective field is not present in the header, then that field is set to Z_NULL to signal its absence. This allows the use of deflateSetHeader() with the returned structure to duplicate the header. However if those fields are set to allocated memory, then the application will need to save those pointers elsewhere so that they can be eventually freed. If inflateGetHeader is not used, then the header information is simply discarded. The header is always checked for validity, including the header CRC if present. inflateReset() will reset the process to discard the header information.

Except for special applications where it is assured that deflate was used with small window sizes, windowBits must be 15 and a 32K byte window must be supplied to be able to decompress general deflate streams. See inflateBack() for the usage of these routines. inflateBackInit will return Z_OK on success, Z_STREAM_ERROR if any of the paramaters are invalid, Z_MEM_ERROR if the internal state could not be allocated, or Z_VERSION_ERROR if the version of the library does not match the version of the header file. */ typedef unsigned (*in_func) OF((void FAR *, unsigned char FAR * FAR *)); typedef int (*out_func) OF((void FAR *, unsigned char FAR *, unsigned)); ZEXTERN int ZEXPORT inflateBack OF((z_streamp strm, in_func in, void FAR *in_desc, out_func out, void FAR *out_desc)); /* inflateBack() does a raw inflate with a single call using a call-back interface for input and output. This is more efficient than inflate() for file i/o applications in that it avoids copying between the output and the sliding window by simply making the window itself the output buffer. This function trusts the application to not change the output buffer passed by the output function, at least until inflateBack() returns. inflateBackInit() must be called first to allocate the internal state and to initialize the state with the user-provided window buffer. inflateBack() may then be used multiple times to inflate a complete, raw deflate stream with each call. inflateBackEnd() is then called to free the allocated state. A raw deflate stream is one with no zlib or gzip header or trailer. This routine would normally be used in a utility that reads zip or gzip files and writes out uncompressed files. The utility would decode the header and process the trailer on its own, hence this routine expects only the raw deflate stream to decompress. This is different from the normal behavior of inflate(), which expects either a zlib or gzip header and trailer around the deflate stream. inflateBack() uses two subroutines supplied by the caller that are then called by inflateBack() for input and output. inflateBack() calls those routines until it reads a complete deflate stream and writes out all of the uncompressed data, or until it encounters an error. The function's parameters and return types are defined above in the in_func and out_func typedefs. inflateBack() will call in(in_desc, &buf) which should return the number of bytes of provided input, and a pointer to that input in buf. If there is no input available, in() must return zero--buf is ignored in that case--and inflateBack() will return a buffer error. inflateBack() will call out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out() should return zero on success, or non-zero on failure. If out() returns non-zero, inflateBack() will return with an error. Neither in() nor out() are permitted to change the contents of the window provided to inflateBackInit(), which is also the buffer that out() uses to write from. The length written by out() will be at most the window size. Any non-zero amount of input may be provided by in(). For convenience, inflateBack() can be provided input on the first call by setting strm->next_in and strm->avail_in. If that input is exhausted, then in() will be called. Therefore strm->next_in must be initialized before calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in must also be initialized, and then if strm->avail_in is not zero, input will initially be taken from strm->next_in[0 .. strm->avail_in - 1]. The in_desc and out_desc parameters of inflateBack() is passed as the first parameter of in() and out() respectively when they are called. These descriptors can be optionally used to pass any information that the caller- supplied in() and out() functions need to do their job. On return, inflateBack() will set strm->next_in and strm->avail_in to pass back any unused input that was provided by the last in() call. The return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR if in() or out() returned an error, Z_DATA_ERROR if there was a format error in the deflate stream (in which case strm->msg is set to indicate the nature of the error), or Z_STREAM_ERROR if the stream was not properly initialized. In the case of Z_BUF_ERROR, an input or output error can be distinguished using strm->next_in which will be Z_NULL only if in() returned an error. If strm->next is not Z_NULL, then the Z_BUF_ERROR was due to out() returning non-zero. (in() will always be called before out(), so strm->next_in is assured to be defined if out() returns non-zero.)

An option can have a help text, a type and a range of possible * values. Options may then be enumerated, read and written to. * * @section avoptions_implement Implementing AVOptions * This section describes how to add AVOptions capabilities to a struct. * * All AVOptions-related information is stored in an AVClass. Therefore * the first member of the struct should be a pointer to an AVClass describing it. * The option field of the AVClass must be set to a NULL-terminated static array * of AVOptions. Each AVOption must have a non-empty name, a type, a default * value and for number-type AVOptions also a range of allowed values. It must * also declare an offset in bytes from the start of the struct, where the field * associated with this AVOption is located. Other fields in the AVOption struct * should also be set when applicable, but are not required. * * The following example illustrates an AVOptions-enabled struct: * @code * typedef struct test_struct { * AVClass *class; * int int_opt; * char *str_opt; * uint8_t *bin_opt; * int bin_len; * } test_struct; * * static const AVOption options[] = { * { "test_int", "This is a test option of int type.", offsetof(test_struct, int_opt), * AV_OPT_TYPE_INT, { .i64 = -1 }, INT_MIN, INT_MAX }, * { "test_str", "This is a test option of string type.", offsetof(test_struct, str_opt), * AV_OPT_TYPE_STRING }, * { "test_bin", "This is a test option of binary type.", offsetof(test_struct, bin_opt), * AV_OPT_TYPE_BINARY }, * { NULL }, * }; * * static const AVClass test_class = { * .class_name = "test class", * .item_name = av_default_item_name, * .option = options, * .version = LIBAVUTIL_VERSION_INT, * }; * @endcode * * Next, when allocating your struct, you must ensure that the AVClass pointer * is set to the correct value. Then, av_opt_set_defaults() can be called to * initialize defaults. After that the struct is ready to be used with the * AVOptions API. * * When cleaning up, you may use the av_opt_free() function to automatically * free all the allocated string and binary options. * * Continuing with the above example: * * @code * test_struct *alloc_test_struct(void) * { * test_struct *ret = av_malloc(sizeof(*ret)); * ret->class = &test_class; * av_opt_set_defaults(ret); * return ret; * } * void free_test_struct(test_struct **foo) * { * av_opt_free(*foo); * av_freep(foo); * } * @endcode * * @subsection avoptions_implement_nesting Nesting * It may happen that an AVOptions-enabled struct contains another * AVOptions-enabled struct as a member (e.g. AVCodecContext in * libavcodec exports generic options, while its priv_data field exports * codec-specific options). In such a case, it is possible to set up the * parent struct to export a child's options. To do that, simply * implement AVClass.child_next() and AVClass.child_class_next() in the * parent struct's AVClass. * Assuming that the test_struct from above now also contains a * child_struct field: * * @code * typedef struct child_struct { * AVClass *class; * int flags_opt; * } child_struct; * static const AVOption child_opts[] = { * { "test_flags", "This is a test option of flags type.", * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX }, * { NULL }, * }; * static const AVClass child_class = { * .class_name = "child class", * .item_name = av_default_item_name, * .option = child_opts, * .version = LIBAVUTIL_VERSION_INT, * }; * * void *child_next(void *obj, void *prev) * { * test_struct *t = obj; * if (!prev && t->child_struct) * return t->child_struct; * return NULL * } * const AVClass child_class_next(const AVClass *prev) * { * return prev ? NULL : &child_class; * } * @endcode * Putting child_next() and child_class_next() as defined above into * test_class will now make child_struct's options accessible through * test_struct (again, proper setup as described above needs to be done on * child_struct right after it is created). * * From the above example it might not be clear why both child_next() * and child_class_next() are needed. The distinction is that child_next() * iterates over actually existing objects, while child_class_next() * iterates over all possible child classes. E.g. if an AVCodecContext * was initialized to use a codec which has private options, then its * child_next() will return AVCodecContext.priv_data and finish * iterating. OTOH child_class_next() on AVCodecContext.av_class will * iterate over all available codecs with private options. * * @subsection avoptions_implement_named_constants Named constants * It is possible to create named constants for options. Simply set the unit * field of the option the constants should apply to to a string and * create the constants themselves as options of type AV_OPT_TYPE_CONST * with their unit field set to the same string. * Their default_val field should contain the value of the named * constant. * For example, to add some named constants for the test_flags option * above, put the following into the child_opts array: * @code * { "test_flags", "This is a test option of flags type.", * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX, "test_unit" }, * { "flag1", "This is a flag with value 16", 0, AV_OPT_TYPE_CONST, { .i64 = 16 }, 0, 0, "test_unit" }, * @endcode * * @section avoptions_use Using AVOptions * This section deals with accessing options in an AVOptions-enabled struct. * Such structs in FFmpeg are e.g. AVCodecContext in libavcodec or * AVFormatContext in libavformat. * * @subsection avoptions_use_examine Examining AVOptions * The basic functions for examining options are av_opt_next(), which iterates * over all options defined for one object, and av_opt_find(), which searches * for an option with the given name. * * The situation is more complicated with nesting. An AVOptions-enabled struct * may have AVOptions-enabled children. Passing the AV_OPT_SEARCH_CHILDREN flag * to av_opt_find() will make the function search children recursively. * * For enumerating there are basically two cases. The first is when you want to * get all options that may potentially exist on the struct and its children * (e.g. when constructing documentation). In that case you should call * av_opt_child_class_next() recursively on the parent struct's AVClass. The * second case is when you have an already initialized struct with all its * children and you want to get all options that can be actually written or read * from it. In that case you should call av_opt_child_next() recursively (and * av_opt_next() on each result). * * @subsection avoptions_use_get_set Reading and writing AVOptions * When setting options, you often have a string read directly from the * user. In such a case, simply passing it to av_opt_set() is enough. For * non-string type options, av_opt_set() will parse the string according to the * option type. * * Similarly av_opt_get() will read any option type and convert it to a string * which will be returned.

Its main two purposes are demuxing - i.e. splitting a media file * into component streams, and the reverse process of muxing - writing supplied * data in a specified container format. It also has an @ref lavf_io * "I/O module" which supports a number of protocols for accessing the data (e.g. * file, tcp, http and others). Before using lavf, you need to call * av_register_all() to register all compiled muxers, demuxers and protocols. * Unless you are absolutely sure you won't use libavformat's network * capabilities, you should also call avformat_network_init(). * * A supported input format is described by an AVInputFormat struct, conversely * an output format is described by AVOutputFormat. You can iterate over all * registered input/output formats using the av_iformat_next() / * av_oformat_next() functions. The protocols layer is not part of the public * API, so you can only get the names of supported protocols with the * avio_enum_protocols() function. * * Main lavf structure used for both muxing and demuxing is AVFormatContext, * which exports all information about the file being read or written. As with * most Libavformat structures, its size is not part of public ABI, so it cannot be * allocated on stack or directly with av_malloc(). To create an * AVFormatContext, use avformat_alloc_context() (some functions, like * avformat_open_input() might do that for you). * * Most importantly an AVFormatContext contains: * @li the @ref AVFormatContext.iformat "input" or @ref AVFormatContext.oformat * "output" format. It is either autodetected or set by user for input; * always set by user for output. * @li an @ref AVFormatContext.streams "array" of AVStreams, which describe all * elementary streams stored in the file. AVStreams are typically referred to * using their index in this array. * @li an @ref AVFormatContext.pb "I/O context". It is either opened by lavf or * set by user for input, always set by user for output (unless you are dealing * with an AVFMT_NOFILE format). * * @section lavf_options Passing options to (de)muxers * Lavf allows to configure muxers and demuxers using the @ref avoptions * mechanism. Generic (format-independent) libavformat options are provided by * AVFormatContext, they can be examined from a user program by calling * av_opt_next() / av_opt_find() on an allocated AVFormatContext (or its AVClass * from avformat_get_class()). Private (format-specific) options are provided by * AVFormatContext.priv_data if and only if AVInputFormat.priv_class / * AVOutputFormat.priv_class of the corresponding format struct is non-NULL. * Further options may be provided by the @ref AVFormatContext.pb "I/O context", * if its AVClass is non-NULL, and the protocols layer. See the discussion on * nesting in @ref avoptions documentation to learn how to access those. * * @defgroup lavf_decoding Demuxing * @{ * Demuxers read a media file and split it into chunks of data (@em packets). A * @ref AVPacket "packet" contains one or more encoded frames which belongs to a * single elementary stream. In the lavf API this process is represented by the * avformat_open_input() function for opening a file, av_read_frame() for * reading a single packet and finally avformat_close_input(), which does the * cleanup. * * @section lavf_decoding_open Opening a media file * The minimum information required to open a file is its URL or filename, which * is passed to avformat_open_input(), as in the following code: * @code * const char *url = "in.mp3"; * AVFormatContext *s = NULL; * int ret = avformat_open_input(&s, url, NULL, NULL); * if (ret < 0) * abort(); * @endcode * The above code attempts to allocate an AVFormatContext, open the * specified file (autodetecting the format) and read the header, exporting the * information stored there into s. Some formats do not have a header or do not * store enough information there, so it is recommended that you call the * avformat_find_stream_info() function which tries to read and decode a few * frames to find missing information. * * In some cases you might want to preallocate an AVFormatContext yourself with * avformat_alloc_context() and do some tweaking on it before passing it to * avformat_open_input(). One such case is when you want to use custom functions * for reading input data instead of lavf internal I/O layer. * To do that, create your own AVIOContext with avio_alloc_context(), passing * your reading callbacks to it. Then set the @em pb field of your * AVFormatContext to newly created AVIOContext. * * Since the format of the opened file is in general not known until after * avformat_open_input() has returned, it is not possible to set demuxer private * options on a preallocated context. Instead, the options should be passed to * avformat_open_input() wrapped in an AVDictionary: * @code * AVDictionary *options = NULL; * av_dict_set(&options, "video_size", "640x480", 0); * av_dict_set(&options, "pixel_format", "rgb24", 0); * * if (avformat_open_input(&s, url, NULL, &options) < 0) * abort(); * av_dict_free(&options); * @endcode * This code passes the private options 'video_size' and 'pixel_format' to the * demuxer. They would be necessary for e.g. the rawvideo demuxer, since it * cannot know how to interpret raw video data otherwise. If the format turns * out to be something different than raw video, those options will not be * recognized by the demuxer and therefore will not be applied. Such unrecognized * options are then returned in the options dictionary (recognized options are * consumed). The calling program can handle such unrecognized options as it * wishes, e.g. * @code * AVDictionaryEntry *e; * if (e = av_dict_get(options, "", NULL, AV_DICT_IGNORE_SUFFIX)) { * fprintf(stderr, "Option %s not recognized by the demuxer.\n", e->key); * abort(); * } * @endcode * * After you have finished reading the file, you must close it with * avformat_close_input(). It will free everything associated with the file. * * @section lavf_decoding_read Reading from an opened file * Reading data from an opened AVFormatContext is done by repeatedly calling * av_read_frame() on it. Each call, if successful, will return an AVPacket * containing encoded data for one AVStream, identified by * AVPacket.stream_index. This packet may be passed straight into the libavcodec * decoding functions avcodec_decode_video2(), avcodec_decode_audio4() or * avcodec_decode_subtitle2() if the caller wishes to decode the data. * * AVPacket.pts, AVPacket.dts and AVPacket.duration timing information will be * set if known. They may also be unset (i.e. AV_NOPTS_VALUE for * pts/dts, 0 for duration) if the stream does not provide them. The timing * information will be in AVStream.time_base units, i.e. it has to be * multiplied by the timebase to convert them to seconds. * * The packet data belongs to the demuxer and is invalid after the next call to * av_read_frame(). The user must free the packet with av_free_packet() before * calling av_read_frame() again or closing the file. * * @section lavf_decoding_seek Seeking * @} * * @defgroup lavf_encoding Muxing * @{ * @} * * @defgroup lavf_io I/O Read/Write * @{ * @} * * @defgroup lavf_codec Demuxers * @{ * @defgroup lavf_codec_native Native Demuxers * @{ * @} * @defgroup lavf_codec_wrappers External library wrappers * @{ * @} * @} * @defgroup lavf_protos I/O Protocols * @{ * @} * @defgroup lavf_internal Internal * @{ * @} * @} * */ #include <time.h> #include <stdio.h> /* FILE */ #include "libavcodec/avcodec.h" #include "libavutil/dict.h" #include "libavutil/log.h" #include "avio.h" #include "libavformat/version.h" #if FF_API_AV_GETTIME #include "libavutil/time.h" #endif struct AVFormatContext; /** * @defgroup metadata_api Public Metadata API * @{ * @ingroup libavf * The metadata API allows libavformat to export metadata tags to a client * application when demuxing.

This is done by * appending a dash character ('-') and the modifier name in the order * they appear in the list below -- e.g. foo-eng-sort, not foo-sort-eng. * - language -- a tag whose value is localized for a particular language * is appended with the ISO 639-2/B 3-letter language code. * For example: Author-ger=Michael, Author-eng=Mike * The original/default language is in the unqualified "Author" tag. * A demuxer should set a default if it sets any translated tag. * - sorting -- a modified version of a tag that should be used for * sorting will have '-sort' appended. E.g. artist="The Beatles", * artist-sort="Beatles, The". * * - Demuxers attempt to export metadata in a generic format, however tags * with no generic equivalents are left as they are stored in the container. * Follows a list of generic tag names: * @verbatim album -- name of the set this work belongs to album_artist -- main creator of the set/album, if different from artist. e.g. "Various Artists" for compilation albums. artist -- main creator of the work comment -- any additional description of the file. composer -- who composed the work, if different from artist. copyright -- name of copyright holder. creation_time-- date when the file was created, preferably in ISO 8601. date -- date when the work was created, preferably in ISO 8601. disc -- number of a subset, e.g. disc in a multi-disc collection. encoder -- name/settings of the software/hardware that produced the file. encoded_by -- person/group who created the file. filename -- original name of the file. genre -- <self-evident>. language -- main language in which the work is performed, preferably in ISO 639-2 format. Multiple languages can be specified by separating them with commas. performer -- artist who performed the work, if different from artist. E.g for "Also sprach Zarathustra", artist would be "Richard Strauss" and performer "London Philharmonic Orchestra". publisher -- name of the label/publisher. service_name -- name of the service in broadcasting (channel name). service_provider -- name of the service provider in broadcasting. title -- name of the work. track -- number of this work in the set, can be in form current/total. variant_bitrate -- the total bitrate of the bitrate variant that the current stream is part of @endverbatim * * Look in the examples section for an application example how to use the Metadata API. * * @} */ /* packet functions */ /** * Allocate and read the payload of a packet and initialize its * fields with default values. * * @param pkt packet * @param size desired payload size * @return >0 (read size) if OK, AVERROR_xxx otherwise */ int av_get_packet(AVIOContext *s, AVPacket *pkt, int size); /** * Read data and append it to the current content of the AVPacket. * If pkt->size is 0 this is identical to av_get_packet. * Note that this uses av_grow_packet and thus involves a realloc * which is inefficient.
