Comment (by taliho):
- Can you confirm that you applied this patch before decoding the 720p
stream?
https://patchwork.ffmpeg.org/project/ffmpeg/patch/20200509173541.7667-1-andriy.gelman@gmail.com/
And that the patch fixes a seg fault? (this is how I understand the ML
thread)
- Please post console output with -loglevel debug option set. Post the log
for the case that works and when it doesn't work.
- Did release 3.4.7 ever work when decoding the 720p stream?
- Please check output of dmesg when decoding fails and post the results if
they contain error messages from the driver
