USB webcam video capture and mjpg format not support #7

Closed AlvinF01 closed 1 month ago

AlvinF01 commented 1 month ago

Tested on both BTT PI2 and Raspberry 3B+. I can confirm that my usb webcam can run fine in rpi 3B+ with 15fps. But cannot get any images in BTT PI2.

It can find my device

FHD Camera: FHD Camera (usb-fd800000.usb-1):
        /dev/video9
        /dev/video10
        /dev/media1

Here is webcamd.log:

There is no 'MJPG' find in v4l2-ctl --list-format-ext

RK3566 should able to support uvc webcam but I think the kernel maybe too old PI2 running on Linux 4.19.232 but rpi 3B+ is running on Linux 6.1.21

there's a ton of usb drivers that aren't installed on the current release of armbian. I sent service an email requesting a new image with the same drivers enabled as the cb1 (which was practically every one as opposed to the pi2, which only has 3 currently enabled)

I found that RK3566 does not have JPEG driver in mainline of linux. https://wiki.pine64.org/wiki/Mainline_Hardware_Decoding So, I don't think armbian will support it in any time soon. Lucky, I buy this board mainly for hosting 7/24 website....
