Clément Bœsch af509f9957 avcodec/proresenc_anatoliy: do not write into chroma reserved bitfields 
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 writing into the reserved bits.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
