Thank you for your advice. i have tried the command you suggest and as a result i got the test video on my PC. Then i tried to use the H264 camera. i got the camera video when i run the command below:

> gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=640,height=480 ! x264enc ! queue ! rtph264pay config-interval=10 pt=96 ! udpsink host=192.168.2.1 port=5600

but a new problem: big delay, about 4 seconds. Then i find the configuration in /camera:

> ! h264parse  
> ! queue  
> ! rtph264pay config-interval=10 pt=96  
> ! udpsink host=192.168.2.1:5600

so i add these in the command:

> gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-raw,width=640,height=480 ! **h264parse****! queue **! rtph264pay** config-interval=10 pt=96**! udpsink host=192.168.2.1 port=5600

return an error: `Warning: Bad pipeline: Unable to link v4l2src0 to h264parse0` but i think these parts are necessary.  
so i try this command:

> gst-launch-1.0 -v **fdsrc**! video/ **x-h264** ,width=640,height=480,framerate=24/1 ! h264parse ! queue ! rtph264pay config-interval=10 pt=96 ! udpsink host=192.168.2.1 port=5600

from [https://discuss.bluerobotics.com/t/ardusub-submodules/194/15?u=rimu](https://discuss.bluerobotics.com/t/ardusub-submodules/194/15)  
with no error, but don’t have the video. just no response.

On my personal computer, I have always used the python code copied from the website：[OpenCV · GitBook](https://www.ardusub.com/developers/opencv.html).  
i have tried all i found but didn’t work. what should i do then? Thank you!
