Gstreamer of AP1302 Previews Glitch Screen

Hello,

I’m developing a driver for On semi’s ap1302. It doesn’t gave any error or anything but when I execute gstreamer command (gst-launch-1.0 v4l2src device=/dev/video0 ! “video/x-raw, format=(string)UYVY, width=(int)1280, height=(int)720, framerate=30/1” ! videoconvert ! ximagesink sync=false | dmesg -w) it outputs as follows:

Initially I thought it was a format missmatch, but after checking with developer kit of ap1302, it seems all correct.

Can you gave me any directions to where to look ?

Thanks

Did you dump the frame data from v4l2-ctl to confirm it.
Does any error message from dmesg?

Hi Shane,

When I execute the following:
v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=“UYVY” --set-ctrl bypass_mode=0 --device=/dev/video0 --stream-skip=100 --stream-count=1 --stream-mmap --stream-to=file.raw

This is the outcome:

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps
<<<<<<<<<<

Did you check the file.raw?

No where does it save ?

I found file.raw but can’t open it. Which command should I use ?

You may need 7yuv tools to open it to check.

I can’t install 7yuv. Are there any alternatives ?

here is the link to a file. Can you check it using 7yuv ?

Unable to show the frames.

I also tried the same method with different formats, but problem still occurs.

The raw data was broken let me suspect the sensor module. Did you verify it on any others platform like PI?

Hi ShaneCCC,

Can device tree settings might be wrong ?

Here is my device tree. I’m using mode 1 of i2c0. Mclk is 4800.
