Hendrik Leppkes	6dd5f95093	avformat/flvdec: fix size desync when reading timestamp offsets The size offset was previously being accounted for in flv_set_video_codec for h264 and mpeg4, instead of being directly accounted for in the spot where its read, which desynced on HEVC streams. For clarity, move the size offset directly to the parsing, similar to how its done for all other header fields.	2 years ago
