[FFmpeg-devel] [PATCH v2 00/15] YUV colorspace filter negotiation

[Niklas Haas]

Split off from my YUVJ removal series. This implements all of the
libavfilter changes needed to fully deprecate YUVJ, but does not yet
remove YUVJ, nor add an AVCodec API for advertising colorspace support.

Update includes all of the feedback that was brought up by Anton. the
major change from v1 is that YUV metadata configured on a link is no
longer strictly required to be consistent with the frames, simply to
avoid breaking users that don't set this link metadata. Effectively,
this allows us to have a grace period where the field functions more
like a hint than an authoritative field.
