I have a TV which has a built in USB record feature (which basically
dumps DVB-T MPEG TS in 2GB chunks). I'd like to pull the audio track
out of something I recorded. VLC happily plays the file and identifies
the video, audio and EPG info in the transport stream, but if, for
example, I run:
avconv -i ... -acodec copy audio.mp3
... I end up with about 2 seconds of silence.
It seems there's a couple of dummy streams and also that the overall
file is prefixed with what looks like null garbage. I know that if vlc
can play it, there's gotta be a way of extracting it, but must admit
that I haven't had any luck thus far.
Any ideas on recommended tools for stubborn MPEG TS demuxing?
