Yes, sounds like it's the opposite of decoding. So basically if we ignore
output colorimetry and read capture colorimetry in v4lobject and then copy
colorimetry field into the sinkpad getcaps.
- add a way to enable/disable colorimetry in v4l2object
- update other element, to make it explicit
+ Src: already disabled
+ Decoder: output only
+ Encoder: capture only
+ Transform: both
+ Sink: enabled
- copy colorimetry from capture to output getcaps in encoder
We should still read back colorimetry in the decoder since we allow color
conversion. Does that make sense ?
