GStreamer: Multiple webcam sources, Picture in Picture to mux on a Jetson Nano, then to be used as a pipeline with belabox >> belabox.net
I'm currently trying to pull two different usb webcams into a pipeline and create a Picture-in-Picture composite, but I keep getting an error like this:
GStreamer Error: gstreamer error from v4l2src1
This is the current pipeline I'm working on that doesn't work;
v4l2src device=/dev/video0 ! image/jpeg,width=1920,height=1080,framerate=60/1 ! nvvidconv ! queue ! comp.sink_0 !
v4l2src device=/dev/video1 ! image/jpeg,width=800,height=448,framerate=60/1 ! videobox left=-4 right=-4 top=-4 bottom=-4 ! nvvidconv ! queue ! comp.sink_1 !

Please note; I have two separate pipelines that can use each webcam, so I know the cameras work and can be used, I just need them to be in the same pipeline have a picture-in-picture composite and work in the belabox environment.
For reference this is a working usb webcam pipeline that works with belabox:
v4l2src device=/dev/video0 ! image/jpeg,width=1920,height=1080,framerate=60/1 !
identity name=v_delay signal-handoffs=TRUE !
nvv4l2decoder mjpeg=1 enable-max-performance=true ! nvvidconv !

Any Ideas?
