AM572x VIN port debug tool

The software team have been notified. They will respond here.

Hi,

Quote,I use "dmabuftest -s 36:480x272 -d /dev/video1 -c 720x480@YUYV",I can not see somethings on the display.

I try "gst-launch-1.0 v4l2src device=/dev/video1 num-buffers=4000 io-mode=4 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)480' ! vpe num-input-buffers=8 ! queue ! kmssink --gst-debug=3",change the num-buffers to 4000,and it don't work too.

BR,

Num-buffers property does not mean that you are increasing buffers. It means "capture 4000" frames.

If it is not set it means that it will capture frames until ctrl+c.

Could you try :

gst-launch-1.0 v4l2src device=/dev/video1 num-buffers=100 io-mode=4 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)480' ! fakesink

Are you sure that 36 is the right connector ID?

Could you try to set io-mode=2?

Hi,

Margarita,I use the "modetest" to get the connector ID,here is the log:

The resolution of my LCD is 480*272，is the connector ID right?

After I set io-mode=2,the result is same as the "io-mode=4".

Any idea? is there a v4l2 tools to test it?
