iam aware of a random threads regression failure for these 2 tests sadly last time i tried (long time ago) i wasnt able to reliably reproduce it, it worked most of the time ... so i had not much luck with debugging it. IIRC the problem even happens with intra only ... If its 100% reproduceable for you, please try old versions to see if its a regression but possibly it was always there ... If its a regression -> find out when we broke it if not try to find a minimal test case, that is ffmpeg-nothreads <cmdline> ffmpeg-threads <cmdline> with minimal cmdline and different output of course it could be a seperate issue (maybe specific to core2 ...) then trying to disble all optims to check if they are the cause might be worth it as well [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB In a rich man's house there is no place to spit but his face. -- Diogenes of Sinope
