Expected Behavior
I expect to see non-intermittent video sequence
Current Behavior
By setting b-frames in the encoder settings, I get a video similar to the one in the link above.
Steps to Reproduce
- Select VAAPI H.264
- Set b-frames
- Start recording
Anything else we should know?
The flathub version does not have such problems. I also tried obs-studio-tytan652 30.2.3 the problem is present in it too.
