Comment (by finlay@…):
The difference between the 0.25 mythtranscode and the 0.26 and 0.27
mythtranscode that causes the changes to the packet pts is in
MPEG2fixup::BuildFrame in change
http://code.mythtv.org/trac/changeset/6c3653cd378aacef10b7706d8b7f71beae41274c/mythtv
where a call to avcodec_encode_video is replaced by a call to
avcodec_encode_video2. I guess that avcodec_encode_video2 zeros out the
pts. I created a patch that restores the original pts value and that
creates a cut file that is identical to the cut file created by 0.25
mythtranscode.
