Hi ,
We have our J6 custom board + sdk 7.04.00.03 , we use tvp5158 to capture a video BT656 source from FPGA.
But sometimes kernel panic will pop up when I use gst-launch or ffmpeg capture command.
My capture command:
gst-launch-1.0 v4l2src device=/dev/video1 num-buffers=1 ! jpegenc ! filesink loc x.jpeg
ffmpeg -f video4linux2 -s 720*480 -i /dev/video1 -vframes 1 y.jpeg
kernel panic
