Hello

I try to use v4l2rtspserver on a LTE Router with OpenWRT and an USB Webcam. If I try to start, I have an 'Segmentation fault' at the end and all stops.

Log Output:

Any ideas how I can find out more about this issue or is it not really possible to stream an UVC USB Webcam?

Hi,

Did you try with latest release ? Using a debugger or strace may help ?
