Any progress? Are the camera drivers and device tree open source so that we can get more eyes on this?

+1 wanted to add my support for this to be doneā¦Itās a great camera, great board, made kind of useless by the fact we canāt control it.
Please check here: common_drivers/drivers/amlisp at khadas-vims-5.15.y Ā· khadas/common_drivers Ā· GitHub
Iāve been testing the OS08A10 on the new (NPU) VIM4.
The ghosting problem only seems to happen when the camera is in 1080p mode - it looks fine in 4k.
(Has anyone tested the imx414 on the new VIM4 - does it work better ?)
We also see the problem that v4l2-ctl doesnāt work in any useful wayā¦
@steely-glint I donāt seem to have the same luck as you. At both 1920x1080 and 3840x2160 I can see the ghosting. I am in a relatively low light, not out in the bright daylight. However, even when I turn on a bright light I can still see this blurry ghosting but maybe it is a little less.
I am using the command provided above as prescribed by @numbqq :
gst-launch-1.0 -v v4l2src device=/dev/media0 io-mode=mmap ! video/x-raw,format=NV12,width=3840,height=2160,framerate=30/1 ! videoconvert ! waylandsink
I would really like to be able to use this camera considering I bought 3 of them for a prototype application. Now I have buyers remorse.
I played with this camera some more in a bright full sun setting. This ghosting problem is not present in a bright setting. This tells me that the problem is probably related to exposure. In a dark setting the ISP may be allowing the exposure to go higher than the frame rate will allow. At 60Hz the exposure and readout time need to be below 16.6ms, 33.3ms at 30Hz.
