Comments.Text: Welcome! Unfortunately, this seems more like a programming question than a video production question, even though it involves ffmpeg. You might get better answers on SO.

ThreadText: # How to write command in android when I m using FFmpeg Native with C++ file?
  
  (Asked by: username_0 on 2019-10-15)
  
  Using FFmpeg lastest version ("Ada") with native code and write command in android .cpp file below it's very simple function VideogetDuration() :
  
  ```
  #include <jni.h>
  #include <string>
  #include <iostream>
  #include <android/log.h>
  #include <unistd.h>
  
  extern "C" {
  #include <libavutil/timestamp.h>
  #include <libavformat/avformat.h>
  #include <libavutil/display.h>
  }
  
      /***
       *
       * @param input - the absolute path to file
       * @returns the duration of file in seconds
       *
       */
      extern "C"
      JNIEXPORT jint JNICALL
      Java_com_ffmpegjni_videoprocessinglibrary_VideoProcessing_getDuration(JNIEnv *env,
                                                                            jobject instance,
                                                                            jstring input_) {
          av_register_all();
          AVFormatContext *pFormatCtx = NULL;
          if (avformat_open_input(&pFormatCtx, jStr2str(env, input_), NULL, NULL) < 0) {
              throwException(env, "Could not open input file");
              return 0;
          }
  
          if (avformat_find_stream_info(pFormatCtx, NULL) < 0) {
              throwException(env, "Failed to retrieve input stream information");
              return 0;
          }
  
          int64_t duration = pFormatCtx->duration;
  
          avformat_close_input(&pFormatCtx);
          avformat_free_context(pFormatCtx);
          return (jint) (duration / AV_TIME_BASE);
      }
  
  ```
