[FFmpeg-devel] [PATCH 0/5] Fix probing display of stream codec properties

[Marth64]

At some point after 4.4.2, the internal properties of AVCodecContext
which revealed useful information (Closed Captions, Film Grain, etc.)
stopped being printed in av_dump_format() and was fixed to its
default value (0) in ffprobe.

For example, ffprobe emits a stream level field "closed_captions"
which simply does not work anymore. This was a useful method
to detect Closed Captions given the correct probe/analyze parameters
for the source file.

This patchset aims to restore the functionality.
