Hello

I've a strange behaviour with VLC (0.8.6a)
A encoder broadcast mpeg2-ts with mpeg2-aac and mpag4-aac. Video is h264
Playing the file is correct, all audios are correct
If I play the broadcast, only mpeg2-aac is decoded

AAC is a MPEG 4 specification. Never heard of the other one you suggest.

H.264 and AAC are both part of the MPEG 4 specification. MPEG TS was created as a Broadcast container for MPEG 2. I don't believe that I have ever seen AAC used in this container, so I'm not sure it will work or not. AC3 with H.264 seems more common for MPEG TS. But the trick at the moment is decoding this combination as most players (codecs) won't do it. However VLC should play this. The issue here could easily be the speed of the computer for the resolution of the file.

Samples would be necessary to see the errors generated. URLs for streams would not be acceptable for the sample files. Only downloads!

AAC on mpetg2-ts surely works as I'm using an encoder that do this.
Speed of the computer is not an issue as my CPU does not go over 65% in decoding the file (P4@2.53GHz) and it decodes correctly the video and audio when it is mpeg2-aac
Where can I send a sample file ? (H264 video + 1 mpeg2-aac audio and 3 mpeg4-aac audios

thanks

You can encode almost anything. Just don't expect any let alone all players to decode it.

there you can upload problematic files, another place is

You're right about the decoder. I'm not sure but I think some set top boxes can decode this
I've posted the file in mpeg4aac_over_mpeg2ts folder of the videolan FTP
Thanks for your help
