I want to know the flow that use Gstreamer and v4l2 plugin to capture video stream.Now, i have two questions:
1.Is (tegra_multimedia_api\samples\12_camera_v4l2_cuda) provide for customer develop their ower apps, not for gstreamer. So, if i use (gst-launch-1.0 v4l2src device=/dev/video0 …) command to capture video stream, the flow don’t enter 12_camera_v4l2_cuda. is it right？
2.(gst-launch-1.0 v4l2src device=/dev/video0 …) This process is similar to the following：
open /dev/video0, format, capbility, stream on, qbuf/dbuf?
