obs crashing #13

Open alejandro-anv opened 5 years ago

alejandro-anv commented 5 years ago

Just downloaded and compiled the github version. By only starting the v4l2sink, obs studio crashes with no error messages.

But if I runs something that uses the device like ffmpeg -f x11grab -r 15 -s 1920x1080 -i :0.0+0,0 -vcodec rawvideo -pix_fmt yuv420p -threads 0 -f v4l2 /dev/video10

and then start v4l2sink, it works ok.

I think v4l2sink may be skipping some configuration.

Kernel version 4.14.119 v4l2loopback from current git version.

Module loaded with this parameters: modprobe v4l2loopback devices=1 video_nr=10 exclusive_caps=1
