FFmpeg/Avconv unable to copy subtitles; Unsupported codec? I've got an mp4 file with these streams (avconv -i file.mp4 or ffmpeg -i file.mp4):

Stream #0.0(eng): Audio: aac, 48000 Hz, stereo, fltp, 125 kb/s (default)
Stream #0.1(eng): Audio: ac3, 48000 Hz, 5.1, fltp, 384 kb/s
Stream #0.2(eng): Video: h264 (Main), yuv420p, 1280x568, 4027 kb/s, PAR 1:1 DAR 160:71, 23.98 fps, 2997 tbn, 50 tbc (default)
Stream #0.3(eng): Subtitle: c608 / 0x38303663, 0 kb/s
Stream #0.4(und): Subtitle: text / 0x74786574
Stream #0.5: Video: mjpeg, yuvj420p, 667x1000 [PAR 72:72 DAR 667:1000], 90k tbn


I am trying to strip out the first audio stream from the file like so:

avconv -i file.mp4 -map 0 -map -0:0 -codec copy file-out.mp4

# OR #

ffmpeg -i file.mp4 -map 0 -map -0:0 -codec copy file-out.mp4


The problem is, I get this error:

Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted


So, I checked if something's wrong with the mp4 file itself:

avprobe file.mp4

# OR #

ffprobe file.mp4


And the output says:

Unsupported codec with id 0 for input stream 3
Unsupported codec with id 94213 for input stream 4


I have no idea what that means. (Apparently something's wrong with the subtitles, but I got the video from iTunes.)


What's wrong?
Can I simply force avconv/ffmpeg to do what I asked of it (i.e. strip the audio stream &amp; copy the rest as it is)? If so, how?
Is there a better alternative for remuxing, that's command-line &amp; actively developed?




Apparently I missed the other errors/warnings in the console output before the final error message, like @aergistal suggested:

[mp4 @ 0x2645420] Codec for stream 0 does not use global headers but container format requires global headers
[mp4 @ 0x2645420] Codec for stream 1 does not use global headers but container format requires global headers
[mp4 @ 0x2645420] Codec for stream 2 does not use global headers but container format requires global headers
[mp4 @ 0x2645420] Codec for stream 3 does not use global headers but container format requires global headers
[mp4 @ 0x2645420] Codec for stream 4 does not use global headers but container format requires global headers
[mp4 @ 0x2645420] track 2: could not find tag, codec not currently supported in container
The fourth stream apparently is a CEA-608 subtitle stream, which during the days of analog television signal transmission was caption data embedded within the video data. Apparently FFmpeg can extract it but can't mux it to a new container.

As for stripping only the audio, MP4Box may be of help.
