Good day,

I have External Usb (v4l2) Cam attached on Qualcomm RB5. After deep investigation, I could not find to create Gstreamer Server with USB cam and then to access it with OpenCV VideoCapture as a client for Preprocessing. Please guide me to create Gstreamer Server based on Usb External Cam and decode it with Video Capture ?

Thanks

Best Regards,

Fikrat Gasimov

After usb cam connected, there should be /dev/videoX, then you can create gstreamer with USB cam by

gst-launch-1.0 autovideosrc device=/dev/videoX ! autovideosink

 

Thanks,

Xiaofeng
