No response

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.

I believe I am experiencing this issue too along with another VAAPI issue that I'll open another issue for after this.
