I purchased an OEM sensor based on the very sensitive SC2210 sensor, but it isn't behaving very well with V4L2 driver. It can stream, and some of the formats are available. But the primary issue is it is not getting most of the camera properties. Things such as exposure control remain undefined. Only Brightness, Contrast and Saturation are defined. Capturing only works with MJPG mode. Defined exposures are forced to use Additive Stack mode. Fortunately I've been informed by the supplier that their clients use OpenCV function libraries to control the cameras. I believe that can be supported by V4L2, but not by default.
If this can be added, or a suitable driver created around OpenCV, compliant UVC USB webcams, that would be very helpful.
Thank you kindly.

There is INDI Webcam driver that uses ffmpeg IIRC.

There is. That would be the V4L2 Driver I was getting some use out of. But it does not appear to use the OpenCV libraries I've been informed of.

It appears someone started to work on an OpenCV CCD driver years ago, but never finished it.

I hope OpenCV cameras can be looked into. These OEM sensors are a pretty good value if one is willing to DIY a body for them. But I was not anticipating this issue after my seamless experience with an OV9281 previously.
The code I found earlier appears to be a good start, but it predates INDI 2.0, so I couldn't get it to compile. It is also missing exposure control. I hope someone can take it on and complete it.
Thank you.
