| ahille | hey, i have a question: if i use v4l2-ctl --all and i get "width/height : 0/0" and "Frames per second : invalid (0/0), can i assume that my videocamera isnt working correctly, or what reason could exist for that? | [08:50] |
| jmleo | ahille, you can probably assume the driver of your camera is not compliant with v4l2
you can use v4l2-compliance tool to test it it sounds like default value for the camera is not set | [08:54] |
| ahille | jmleo, could u tell me if and how i could change the the default value in a way that it works out? or cant i use v4l2 at all for that camera if v4l2-compilance says "Not Supported" mutliple times | [08:59] |
| jmleo | what is the camera model | [09:00] |
| ahille | can i loo,k that up somewhere? im afraid i dont myself :/ | [09:02] |
| jmleo | ahille, is it a usb camera ? lsusb is a start | [09:02] |
| ahille | no, its an integrated camera
i guess intern the camera is called atomisp-css2400b0_v21, judging from the dmesg output | [09:03] |
| jmleo | what is your kernel version (uname -a)
oh, is it something like a chromebook or android based ? | [09:06] |
| ahille | no, its an tablet using centos
its an x86_64 kernel as centos cant other then 64-bit | [09:09] |
| ..... (idle for 20mn) | ||
| lyakh | wow, was centos preinstalled on that tablet? | [09:31] |
| ahille | no, it usually uses windows, due to that im not quite sure IF there is a way to use this camera, beside that someone had to write it first | [09:41] |
| lyakh | hm, but where does that atomisp then come from? I don't see such a V4L driver in the mainline
ok, I see some out-of-tree drivers for that on the internet | [09:47] |
| ahille | well, i dont know if thats important, but im using a custom kernel, but i cant give you specific details, as it was given to me by a colleague, mayby thats where it comes from :/ | [09:53] |
| jmleo | yes, sounds like a out-of-tree driver, so, here is your issue... | [10:00] |
| lyakh | Right, so, that kernel uses an out-of-tree V4L driver for the Atom ISP camera bridge, and that driver doesn't seem to work very well for you, that's all I can tell you, sorry. Don't know what your goal is - either you want to start a large-scale debugging and development effort with this, or you just plug in a webcam and forget the built in one | [10:00] |
