[FFmpeg-devel] [PATCH v5 3/3] ffmpeg: Deprecate display rotation override with a metadata key

From: Jan Ekström <jeebjp at gmail.com>
Now that we have proper options for defining display matrix
overrides, this should no longer be required.
fftools does not have its own versioning, so for now the define is
just set to 1 and disables the functionality if set to zero.
