streaming errors in ffmpeg 4.2.1

[martingercke]

There are a few streaming issues that were fixed in ffmpeg 4.2.2.
I am facing problems with streams breaking up after some time with an error "Stream failed: avcodec_send_packet() failed: Invalid data found when processing input"
I have good faith that this issue will be fixed with ffmpeg 4.2.2 as discussed here:
acaudwell/Gource#216

If you anyway consider upgrading ffmpeg, then maybe it would make sense to consider a newer version:
https://git.ffmpeg.org/gitweb/ffmpeg.git/tags

But I don't know about interface changes and stability, so of course that's completely up to you @jacobbo.
Thanks in advance!
