[mythtv] Call for testing branch devel/ffmpeg-resync (mpegts-harmonize)

[Scott Theisen]

Hello all,

Following the merge of my FFmpeg cleanup commits to master, branch 
devel/ffmpeg-resync now contains my changes harmonizing our version of 
the mpegts demuxer with FFmpeg 4.4's version.

The main change versus FFmpeg that I couldn't test is DSMCC/MHEG, so 
could someone with access to those streams confirm that it works the 
same as master?

Other testing is, of course, also welcome.

Thanks,

Scott Theisen
