New submission from James <[email protected]>:
On certain recordings ffmpeg doesn't correctly identify the AC3 5.1
stream.
I have uploaded a sample as CantDemuxAC3.wtv to your ftp server - to
/MPlayer/incoming/CantDemuxAC3FromWTV
The following is the output from
ffmpeg -v 9 -loglevel 99 -i CantDemuxAC3.wtv :
