[libcamera-devel] [PATCH v5 0/7] Colour spaces

[David Plowman]

Hi again

Here's v5, which is different to v4 only in that I've rebased the
Raspberry Pi PH changes (the final commit) on top of its recent
media-controller-ification. It's not a big change, but things are very
slightly different there now.

This has shown up one little niggle, which is that the V4L2 subdevice
now complains about retrieving an undefined colour space - from the
metadata pad! Currently I've left the warning in but added the pad
number in the message. The metadata pad is easy to spot in practice
because it always has a non-zero pad number. But is there a proper way
to know this?

Thanks

David
