create_camera_source_bin
This command works for me.$ gst-launch-1.0 v4l2src device=/dev/video0 ! 'image/jpeg, width=1280, height=720, framerate=10/1' ! nvv4l2decoder ! nvvideoconvert ! 'video/x-raw(memory:NVMM),format=NV12' ! mux.sink_0 nvstreammux name=mux width=1280 height=720 batch-size=1 ! fakesink
In my config is
[source0]
enable=1
#Type - 1=CameraV4L2 2=URI 3=MultiURI
type=1
camera-width=1280
camera-height=720
camera-fps-n=10
camera-fps-d=1
camera-v4l2-dev-node=0
What do I need to change in the create_camera_source_bin?
