Comment (by cs9k):
"BTW. If I understand this issue, here we have a thing that if we encode
and then immidiatelly stream that to udp, be have broken picture (because
replacing by guess does not work (?))"
Aye, with b_ref_mode on middle, Twitch and YT properly ingest the output
from OBS, and ffmpeg's command-line output and resulting files work just
fine despite throwing the dts/pts error.
I suppose, thinking out loud about it, OBS Studio inability to handle the
dts/pts error and how ffmpeg resolves it, is an OBS Studio issue. If you
can confirm that that is the case (assuming nothing needs to be 'fixed'
with ffmpeg), I can pursue that avenue for a resolution.
