Adding FFMPEG's AMR support to VLC

[chrget]

Hello everybody,

has anyone tried adding AMR support to VLC via an AMR-enabled FFMPEG? I was under the impression that it would be sufficient to add the codec to the list in modules/codec/ffmpeg/ffmpeg.c, but that does not seem to be the case.

The codec is recognized, probably working as well (?), but the resulting audio is seemingly discarded by VLC due to timing issues:

Code: Select all

[00000154] main audio output warning: buffer is 390000 in advance, triggering downsampling [00000154] main audio output warning: computed PTS is out of range (372267), clearing out [00000154] main audio output warning: timing screwed, stopping resampling

This is being repeated all through playback (obviously with varying PTS values). Am I missing something here? If so, can someone please point me in the appropriate direction?

Thanks in advance.

Best regards,
Chris.

BTW, the problem report above has been fixed in the development version.

I did not find a development version of VLC with AMR support - can you please help ?
Do u have this build?

Do u know other tool that can get RTSP stream (mpeg4 and AMR ) and convert it to MPEG2 TS or just save it to file?

the reason as to why VLC currently doesn't include AMR by default in the binary is because the sources for AMR are not compatible fully with GPL (in our interpretation of the GPL). No one has developed full GPL compatible sources yet, therefore VLC does not have a AMR decoder. (though it can be eaisly build with one if you put some effort in it.)

I did try to build one - believe me. I'm working on that for several days by now with no success.

PLEASE HELP!

Can you give me some instructions?

will be much appreciated,

Sara
