dear,

i modify driver &dts for support YUV sensor, but err as follow:

modify:

camera_common.c
           {
                   MEDIA_BUS_FMT_UYVY8_2X8,
                   V4L2_COLORSPACE_SRGB,
                   V4L2_PIX_FMT_UYVY,
           },

sensor_common.c

else if (strncmp(pixel_t, "yuv_yuyv8", size) == 0)
                 *format = V4L2_PIX_FMT_UYVY;

capture video cmd:
v4l2-ctl -d /dev/video0 -w --verbose --set-fmt-video=width=1920,height=1080 --stream-mmap --stream-count=1 --set-ctrl bypass_mode=0 --stream-to=/tmp/stream.raw

hello JiaZW

please resolve below failure.

libv4l2: error setting pixformat: Invalid argument
VIDIOC_S_FMT: failed: Invalid argument

you may also check similar topic, Topic 1051076 for reference. thanks

@JerryChang

Is this problem caused by v4l2 or is it caused by a driver & dts modify error ？

4

hello JiaZW,

please refer to Camera Architecture Stack,
since you already extend YUV support formats, you’ll also need to dig into sensor driver to check which function call cause the VIDIOC_S_FMT failure.
BTW, you may also refer to Topic 1051076 as best-practice.
thanks

@JerryChang

Is there a driver & dts of YUV sensor for reference ？？

6

At present, there is no way to debug YUV sensor

7

hello JiaZW,

we don’t have YUV sensor reference drivers, suggest you search for similar topics for debug tips.
thanks

thanks

9

Is there a YUV sensor reference driver now? on xavier

hello liu.jialu

No, we don’t provide YUV sensor drivers for reference.
you might contact with Jetson Preferred Partner for camera solutions.
thanks
