How to run vila_live with IP camera?

[Shehjad-Ishan]

Currently, I am using ffmpeg to stream the camera as v4l2 loopback device.

ffmpeg -rtsp_transport tcp -i 'rtsp://admin:jbl12345@192.168.0.149:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif' -fflags +genpts -fps_mode passthrough -pix_fmt yuv420p -r 25 -f v4l2 -s 1280x720 /dev/video3

But getting this error when running vila_live. pixel_format= "YU12".

Caught signal 11 (Segmentation fault: invalid permissions for mapped object at address 0x7f143b205040)
