Hi @alvaro.tx ,

The GStreamer pipeline I used is as follows:

// 1 channel
gst-launch-1.0 v4l2src device=/dev/video2 ! video/x-raw,width=1920,height=1080,framerate=30/1 ! fpsdisplaysink video-sink=waylandsink text-overlay=false sync=false -v
// 4 channel
gst-launch-1.0 imxcompositor_g2d name=comp \
  sink_0::xpos=0 sink_0::ypos=0 sink_0::width=960 sink_0::height=540 \
  sink_1::xpos=0 sink_1::ypos=540 sink_1::width=960 sink_1::height=540 \
  sink_2::xpos=960 sink_2::ypos=0 sink_2::width=960 sink_2::height=540 \
  sink_3::xpos=960 sink_3::ypos=540 sink_3::width=960 sink_3::height=540 ! \
  video/x-raw,framerate=30/1 ! fpsdisplaysink video-sink=waylandsink text-overlay=false sync=false -v \
  v4l2src device=/dev/video2 ! video/x-raw,width=1920,height=1080,framerate=30/1 ! comp.sink_0 \
  v4l2src device=/dev/video3 ! video/x-raw,width=1920,height=1080,framerate=30/1 ! comp.sink_1 \
  v4l2src device=/dev/video4 ! video/x-raw,width=1920,height=1080,framerate=30/1 ! comp.sink_2 \
  v4l2src device=/dev/video5 ! video/x-raw,width=1920,height=1080,framerate=30/1 ! comp.sink_3

I referred to the NXP Community for the device tree I provided last time:
