[Matroska-devel] No audio using Haali splitter for TS files with MPEG4-AVC (h264) + AAC data

Nevermind I found a convenient way to read these files...
And I also found out that I should have posted this on
doom9.org's forums instead. Sorry for bothering the
Matroska developers ! :p
My method is the following :
1- Demux the audio part of the stream using DGAVCDec,
keeping the default name for the aac file that is
2- Open the TS file with MPC. The AAC file is magically
detected by MPC that will read the audio file in sync
with the video automatically ! (seeking works too !)
Gabest is the best !
It would still be great if Haali's splitter could
extract the audio too, so I could use one single
DirectShowSource() in AviSynth to use any AviSynth
compatible program to re-encode the stream.
And I still found no way to directly read the live TV
streamed over RTSP using MPC and not VLC.
