Hello, I am using voxl2 flight deck.

Now, I want to stream video from voxl2 to another device as gstreamer.

I can see the two cameras are available, but I can not use gst-launch-1.0 with v4l2src.

There is 4 video devices like this.

However, anyone can not be used as v4l2src.

I want to use following pipeline.
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-h264,width=1920,height=1080,framerate=24/1 ! h264parse ! rtph264pay ! udpsink host=0.0.0.0 port=5600

Is there any way to use camear with v4l2src?

@Dongoo-Lee Can you use voxl-streamer?

@Eric-Katzfey Yes, I can use voxl-streamer right now. but I want to modify pipeline with gst-launch.

I think voxl-streamer config file is quite simple (only some parameter including bitrate..). Can I do more with voxl-streamer??
