Hi, some feedback from one of the libRIST developers:

Testing this patch (via diff found
on:
https://patchwork.ffmpeg.org/project/ffmpeg/patch/20210126205145.20448-1-one...@gmail.com/
) I've noticed FFmpeg is not reading fast enough from the libRIST FIFO
buffer (which is limited to 1024 packets) causing it to overrun.
Unfortunately libRIST had a bug where it kept incrementing the buffer
counter indefinitely, this has now been fixed and it will log an error
whenever this happens (which is very often with FFmpeg).
FFmpeg will need to read the FIFO faster, by calling the librist_read
function more often. If that's not possible within the design of FFmpeg
the module can either:



Unfortunately some other devs disagree with initial patch and thus this
issue.

Could you pinpoint which change/discussion are you referring to here?

Thanks,
Marton
