Comment (by tracey_pooh):
... and sorry if "critical" is Big Alarms -- I meant to explain why I
picked that.
We at Internet Archive try to help our PEG (Public Access, Education, &
Government)
brothers and sisters and are transcoding for some of them (as well as
video archiving).
The good folks at Seatle Community Media alerted us to the fact that none
of their
programs were being "accepted" by their Televue hardware systems suddenly
after
my Mar 21 ffmpeg build. It eventually led back to this bad muxrate in
the pack header
causing Televue to reject the mpeg2s that we make.
Best I can tell, this muxrate is wrong for every MPEG2-PS created by
ffmpeg,
so hence the "critical" selection. Apologies in advance if that was too
extreme. 8-)
Rock on, ffmpeg!
