[Freeswitch-dev] added mp3 codec, please review

[Seven Du]

Hi, 

To record mp4 with libmp4v2, I found the standard audio format is AAC but FS does't support, so I tried added a mp3 encoder, hopefully it works.

I have successfully record into mp4 but audio doesn't playback, videos looks fine.

Anyone can help review the code and give some input is appreciated.

Playback Errors in VLC looks like this:

I use mod_mp4v2(C) with libmp4v2 to record mp4 file, if also been interested I could share on github or check into the video-media-bug branch. But I really want to merge with mod_mp4 though which is C++ based.


@Paulo, I also CC you this message as I haven't figure out how to write hint track you input is welcome.

Thanks.
