Datatype of metadata is the same with it of rawdata

[Mr.Elephant]

My sensor can output 640480 rawdata, and 2480 metadata with data types 0x2c and 0x12, respectively.

I change the datatype of metadata from 0x12 to 0x2c through serdes and deserdes.
And I also change the device tree.

Is this approach feasible?

[Mr.Elephant]

when I test it with v4l2 command

v4l2-ctl --set-fmt-video=width=640,height=482,pixelformat=RG12 --stream-mmap --set-ctrl=sensor_mode=0  -d /dev/video0

the dmesg shows below:

trace log:
trace.log (22.0 MB)
If this is feasible, please help to see what went wrong.Thanks!

The log tell short frame.
Check the size is modify correct by below command.

v4l2-ctl --list-formats-ext

[Mr.Elephant]

Thanks for your quick reply.

pcai@pcai-desktop:~$ v4l2-ctl --list-formats-ext

ioctl: VIDIOC_ENUM_FMT
        Type: Video Capture

        [0]: 'RG12' (12-bit Bayer RGRG/GBGB)
                Size: Discrete 640x482
                        Interval: Discrete 0.017s (60.000 fps)

[ShaneCCC]

The size is correct. Could you try report 640x480?

[Mr.Elephant]

@ShaneCCC

Could you try report 640x480?

sorry, I can’t understand what you mean.

[ShaneCCC]

The trace log tells the receive less line than report.
Check the log by report the less height.
