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.
