ADV7282-m black and white color issue video output

kamalesh1 · February 13, 2025, 5:24pm

Hi,

I am using Jetpack 5.1.2. I got video ouput from ADV7282-m chip. But In video output, there is no color(only black and white) and grey line also there. How to debug this?

I have attached the output of my video node responses.

v4l2-ctl -d /dev/video0 --get-fmt-video

Set the alignment to 256 by below command to try.

vl42-ctl -c preferred_stride=1536

kamalesh1 · February 14, 2025, 4:36am

Hi Shane,

Thank you very much for your reply. But, Is there any element for color?

I am getting black and white, there is no other colors.

Regards,
Kamalesh

ShaneCCC · February 14, 2025, 4:39am

Dump the frame by v4l2-ctl to check.
If the same that could be the source only output Y data.

Thanks

kamalesh1 · February 14, 2025, 4:54am

Hi,

How to dump and check my video data using v4l2?
Could you please advise us?

ShaneCCC · February 14, 2025, 5:10am

Use below command to save to file and use 7yuv to check it.

v4l2-ctl --set-fmt-video=width=720,height=507 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=test.raw -d /dev/video0

kamalesh1 · February 14, 2025, 6:29am

Hi,

I have received 0 bytes of raw video file from this command. Why it is?

Regards,
Kamalesh

ShaneCCC · February 14, 2025, 7:00am

Add --stream-skip=100 to try.

kamalesh1 · February 14, 2025, 7:20am

I have tried. Now also same issue.

kamalesh1 · February 14, 2025, 10:34am

Hi,

For your reference, I have attached my dmesg while fetching video using gstreamer. I have seen discarding frame error.

Is this might be a issue for color changing?
I am using this below pipeline to fetch video.

Could you please help me to identify the issue?

Apply this patch to try.

Hi Shane,

I already applied this patch. Still same condition.

kamalesh1 · February 17, 2025, 1:46pm

Hi Shane,

Please give the explanation for below queries:
I have given the PAL Video resolution of 742x582 to ADV7282-m. But I have seen the video node creation for 720x507. This is NTSC resolution right?
So, driver loaded and created the node for NTSC, not for PAL?

v4l2-ctl -d /dev/video0 --all

Is this the reason behind this frame loss and color loss?

Thanks.

For this you need to check the ADV7282 driver. Jetson only receive the data output from the sensor. The sensor should report correct size and format.

kamalesh1 · February 18, 2025, 7:08am

Hi,

Update:-
After changing the driver configuration, we have successfully received video.

Thanks for your support.

Kamalesh

ShaneCCC · February 18, 2025, 7:22am

Could you share your configuration to help forum users.

Thanks

kamalesh1 · February 18, 2025, 7:23am

Hi,

Yes, I have intialized(init_function) my driver file as PAL. Earlier, It was configured as NTSC.

Thanks.
