5. the picture below is abnormal
My Questions is:
a. Why is the color abnormal and how to modify and test
b.Play with the nvarguscamerasrc plugin, showing no camera.Why is this?
gst-launch-1.0 nvarguscamerasrc sensor_id=0 ! ‘video/x-raw(memory:NVMM),width=1280, height=800, framerate=21/1, format=NV12’ ! nvvidconv flip-method=0 ! ‘video/x-raw,width=960, height=616’ ! nvvidconv ! nvegltransform ! nveglglessink -e
