I have OBS working with both a standard install through apt and as a snap.
OBS launches just fine and is able to connect to my NDI stream pulling both audio and video.
The problem is when I go to launch V4L Video Output it opens a title bar that is super wide and I get the error message:
OBS then crashes with a Segmentation fault (core dumped)
This happens on both the standard install and the snap install.
From what I have been reading, this might be caused by my monitor resolution. I haven't had the chance to disconnect all but one of my monitors to run a test yet. But I will attempt that in the next day or two.
Here is my log file from the OBS standard:
Is there a fix for this, or a way specify the window size for it to open to?
