Never return V4L2_COLORSPACE_DEFAULT. From the standard:
"""
In the absence of this descriptor, or in the case of
“Unspecified” values within the descriptor, color matching
defaults will be assumed. The color matching defaults are
compliant with sRGB since the BT.709 transfer function and
the sRGB transfer function are very similar.

It is difficult to know without access to the hardware :) Maybe you can replicate what causes the error with just v4l-ctl calls and then ping the manufacturer with a simple repro. > > > > > > > Best regards! -- Ricardo Ribalda ^ permalink raw reply [flat|nested] 15+ messages in thread

Hmm, think that might be the way the camera might be indicating commands are being sent too fast?

Hmm, looking at a pcap the windows uvc driver looks like it might be sending a bunch of GET_CUR multiple times for the same request, maybe it makes sense to try and emulate the behavior there. > > > > > > > It is difficult to know without access to the hardware :) > > > > > > Maybe you can replicate what causes the error with just v4l-ctl calls > > > and then ping the manufacturer with a simple repro. > > > > > > > > > > > > > > > > > > > > > > Best regards! > > > > > > > > > > > > -- > > > Ricardo Ribalda > > > > -- > Ricardo Ribalda ^ permalink raw reply [flat|nested] 15+ messages in thread

Seems it was just due to the timeout being too short, this seems to fix the issue: https://lore.kernel.org/linux-media/20211114085236.2345589-1-james.hilliard1@gmail.com/ The camera now passes all v4l2-compliance tests with this change applied. > > > > > It is difficult to know without access to the hardware :) > > > > Maybe you can replicate what causes the error with just v4l-ctl calls > > and then ping the manufacturer with a simple repro. > > > > > > > > > > > > > > > > > Best regards! > > > > > > > > -- > > Ricardo Ribalda ^ permalink raw reply [flat|nested] 15+ messages in thread
