Hi Andriy, Is there any way to know the details of failure for this patch? Like OS, configuration, gcc version, etc. It looks good on my local Ubuntu with gcc 9.3, but show fails in patchwork checks: https://patchwork.ffmpeg.org/project/ffmpeg/patch/[email protected]/ Fei Thanks _______________________________________________ ffmpeg-devel mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
