[mythtv-users] Mythtranscode Lossless cut Changes

[Justin Alcorn]

Mythtv 0.28pre on Ubuntu 14.04.1

I'm using a script to losslessly cut commercials out of my HRHomerun
recordings.  The command used is quite simple:

mythtranscode --honorcutlist -m -i ${INPUTFILE} -o ${WORKFILEBASE}.mpg

Everything else in the script is mythutil cutlist or mythcommflag, or other
things that don't change the file.  That's the only command that changes
the file.

When I record something off the local Fox affiliate, the default track, and
the only one available for the MythTV Plex plugin, is the Audio Track for
the visually impaired.  The first track has been swapped with the second.

The original file looks like this to ffmpeg:

mythtv at gossamer:~$ ffmpeg -i
/var/lib/mythtv/recordings/3081_20141111010000.mpg.old  2>&1 | grep Stream
    Stream #0:0[0x31]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002),
yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 59.94 fps, 59.94 tbr, 90k tbn, 119.88
tbc
    Stream #0:1[0x34](eng): Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz,
stereo, fltp, 448 kb/s
    Stream #0:2[0x35](spa): Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz,
stereo, fltp, 192 kb/s


mythtv at gossamer:~$ ffmpeg -i
/var/lib/mythtv/recordings/3081_20141111010000.mpg  2>&1 | grep Stream
    Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p, 1280x720 [SAR
1:1 DAR 16:9], 59.94 fps, 59.94 tbr, 90k tbn, 119.88 tbc
    Stream #0:1[0x81]: Audio: ac3, 48000 Hz, stereo, fltp, 192 kb/s
    Stream #0:2[0x80]: Audio: ac3, 48000 Hz, 5.1(side), fltp, 448 kb/s

That's a lot of changes, not just cutting out commercials.  I found some 6
year old bug reports that said that the issue of mythtranscode swapping teh
audio tracks was solved in 0.21, but either we've got a regression bug or
something really weird is happening to me.
