We need to write [GPIO](https://github.com/pikvm/pikvm/blob/master/pages/gpio.md) plugin for this. I don't have a device to make and test this.

Why did you close it? Any plugins, even wireless ones, work internally via the gpio protocol. It's just our abstraction, not the physical gpio.

There is the CMD plugin to run scripts: https://docs.pikvm.org/gpio/#cmd

Hello. Sorry for the long answer, I'll try to figure it out, this is an unusual case.

It's actually related with limited colorspace of the source. H.264 **decoder** on the client side can handle it natively using a special flag in bitstream, but JPEG not. I couldn't...

NV12 format is not supported. Use UYVY, YUYV, RGB24, JPEG or MJPEG.

No. First you need to make sure that the camera supports the desired formats. Show `v4l2-ctl --list-formats-ext -d /dev/kvmd-video`.

Sorry, but no chance to enable it. It has no supported formats.
