HI all:
Just now we want to use the videomixer plugin to stitching the video
out board is a custom board and the processor sdk is 3.0.
below is my test command but it will be error.
gst-launch-1.0 -v --gst-debug=3 videomixer name=mix ! vpe ! 'video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1080, framerate=(fraction)60/1' ! kmssink \
videotestsrc pattern=13 ! 'video/x-raw, format=(string)YUY2, width=(int)200, height=(int)100, framerate=(fraction)60/1' ! mix. \
videotestsrc pattern=18 ! 'video/x-raw, format=(string)YUY2, width=(int)640, height=(int)480, framerate=(fraction)60/1' ! mix.
please see the debug info
