Hi
I have a mp4 video file which has 3 oudio stream
1)AAC stereo
2)AC3 5.1
3)AACstereo
avi demux 2.6 r8121 fils to process stream # 2 .I guess the reason is that it detecs the stream as stereo then in reality it's 6 channel audio. I read in forums that mp4 does not support AC3 and DTS streams in ISO specification but it would make sense to implement this feature to support such issues.
Regards Arsham
A sample would help
sorry don't know any tool that can split the file. one of the same type of packed mp4 is in http://thepiratebay.se/torrent/7490024/The_Bourne_Identity_%282002%29_1080p_iTunes (http://thepiratebay.se/torrent/7490024/The_Bourne_Identity_%282002%29_1080p_iTunes) need torrent client.
don't use videos with mp4 AC3 5.1.
