[FFmpeg-devel] [PATCH 5/5] avcodec/proresenc_anatoliy: do not write into chroma reserved bitfields

Clément Bœsch u at pkh.me
Sun Jan 7 20:16:47 EET 2024 

The layout for the frame flags is as follow:

   chroma_format  u(2)
   reserved       u(2)
   interlace_mode u(2)
   reserved       u(2)

chroma_format has 2 allowed values:
   0: reserved
   1: reserved
   2: 4:2:2
   3: 4:4:4

interlace_mode has 3 allowed values:
   0: progressive
   1: tff
   2: bff
   3: reserved

0x80 is what we expect for "422 not interlaced", and the extra 0x2 from
0x82 is actually writting into the reserved bits.
