Part Number: PROCESSOR-SDK-AM62A
Hi all,
I am trying to display a video captured using a USB camera - LI-IMX424-GW5400-FPDLINKIII
using the HDMI output port.
I have managed to make it work using a standard Logitec webcam withthe following Gstreamer command:
gst-launch-1.0 v4l2src device="/dev/video2" ! video/x-raw, width=1024, height=576, framerate=15/1 ! kmssink driver-name=tidss
It work well, except that the default app is still running in the background (this is not the issue).
I Have tried different methods to run the USB camera (LI-IMX424-GW5400-FPDLINKIII ) on the AM62A,
But I cannot get it right.
First - when I try to get the supported format (v4l2-ctl --list-formats -d /dev/video2) I get an error, but the video format of the YUYV channel is currect.
When I run these commands on my personal computer it shows no error message so the camera is not the issue and I can view the video using qv4l2 app.

The next step I've done is to run the following Gstreamer command:
gst-launch-1.0 v4l2src device="/dev/video2" ! video/x-raw, width=640, height=480 ! kmssink driver-name=tidss
But the default app is still the one that displays using HDMI.
I guess I need to idle the demo app and then run the gst line but I didn't mange to find any reference.
