MP4 and G.711

[mariyan]

I want to mux G.711 audio and mpeg4 video into mp4 file.
I know that it is possible but don't know how to do this.
Unfortunately it seems that 3ivx muxer cannot do this.
Thanks.

Could be possible with MP4Box( http://gpac.sourceforge.net/ ). But I am not sure, ask there : http://sourceforge.net/forum/?group_id=84101 .

Could be that the ObjectDescriptor is similar to the sample (scene.bt) here:
http://www.comelec.enst.fr/~dufourd/mpeg-4/Bifs_Primer/mp4tool/Audio/.

Audio in that sample is G723. But I don't know if this objectTypeIndication is right for G723 or is the same with G711.

Muxing mp4 video is easy, MP4Box create the right ObjectDescriptor. Look at the way it is done here (MP4Sub): http://sourceforge.net/projects/mp4menu

(193)0xC1 is user private (0xC0 - 0xFE) objectTypeIndication

hm, never heard about G.711...

if its not supported by the mpeg-4 standard, i highly doubt that there is a tool which can mux it into .mp4
