Comment (by ramitbhalla):
This is very incorrect:
Guessed Channel Layout for Input Stream #0.0 : stereo
It should give this (like the TS file does):
Stream #0:1[0x101](eng): Audio: mp3 ([3][0][0][0] / 0x0003), 0
channels, s16p (hearing impaired)
I don't understand why in the TS file it reports it correctly as 0
channels while in the WTV file it "guesses" 2 channels.
If this is correctly done, then I think it solves the problem of selecting
the "wrong" default audio also. I remember reading in some documentation
that ffmpeg chooses the audio track with the highest bit rate/channels etc
- which is EXCELLENT, except this guessing has completely messed it up.
3rd Party application depend heavily on the output of the "Stream #" line,
so any mess up there will completely mess things up.
