Im can run this on my jetson:
./deepstream-app -c deepstream_app_config_yoloV3.txt
using a video stream from a file without any problems.
But when I change type to 1 to run a camera (I tried both raspberry pi camera and logitec webcam):
#Type - 1=CameraV4L2 2=URI 3=MultiURI
I get this error:
ERROR from src_elem: Internal data stream error
i got to know “Gstreamer provides different commands for capture images were two is nvarguscamerasrc and v4l2src.” in https://developer.ridgerun.com/wiki/index.php?title=Xavier/Video_Capture_and_Display/Software_Support/GStreamer, and my kernel is
Linux 4.9.140-tegra aarch64,so I can only use nvarguscamerasrc.
my question is : "CameraV4L2 " stand for v4l2src, What stands for nvarguscamerasrc
