Hi why is sizeof(HEVCVPS) is 7463476 ? If you think about this for a moment, a VPS in the bit stream is what, 5 bytes ? Now iam not even talking about someone proving you a 10mb file with a million VPSs 7TB allocation, memsets memcpies, ... But even with a totally normal file 7mb is easily bigger than the frame buffer that wastes memory, it wastes cpu time, it wastes data cache thx -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Frequently ignored answer#1 FFmpeg bugs should be sent to our bugtracker.
