MEDIA_BUS_FMT_Y10_1X10 support #2

Closed martin-jansen closed 3 years ago

martin-jansen commented 3 years ago

I am trying to connect an OV7251 to my S3 board. The OV7251 uses MEDIA_BUS_FMT_Y10_1X10 and because there is no support in the mipi csi driver I have tried to add this. mipi_csi2_y10.zip

The communication with the camera module is working. Only the output is what I am expecting to receive. I think I have added the Y10 correct but obviously I have made an error along the way. If you have some time to look at my patch I would really appreciate it.

hi martin, i use your patch, but i cannot get the Y10 picture（i can get yuyv picture）， and got the error The pixelformat 'Y10' is invalid , the following is my cmd. do you know how to solve this problem? or how to get the right picture ? Look forward to your reply. # v4l2-ctl --set-fmt-video=width=640,height=480,pixelformat=Y10 --stream-mmap --stream-count=1 --stream-to=out.raw

You will need a little bit more code to make the Y10 work. Can you try the attached patch as well. ​​

i use the wrong cmd. Thank Martin for his help. the right cmd is
# v4l2-ctl --set-fmt-video=width=640,height=480,pixelformat='Y10 ' --stream-mmap --stream-count=1 --stream-to=out.raw
