I am trying to test running an opencv gstreamer plugin on a live camera capture. When I run try to run the following pipeline it fails to link.
gst-launch-1.0 -vvv nvcamerasrc fpsRange='30.0 30.0' ! "video/x-raw(memory:NVMM), width=(int)2592, height=(int)1944,format=(string)I420, framerate=(fraction)30/1" ! videoconvert ! facedetect ! videoconvert ! autovideosink
I have tried similar pipeline on my main machine and they seem to work. All I can think is that it cannot take the video data out of the memory:NVMM space. Is there anyway to transfer data from video/x-raw(memory:NVMM) to video/x-raw?
