Pipewire Audio Video latency: huge latency on video
I am using OBS studio to perform some recording of audio + video from a webcam and recording of the desktop. The audio source comes from a USB audio source and needs to be low latency. I have set up pipewire for low latency (preempt=full as a boot option). I set the buffer size like this:
pw-metadata -n settings 0 clock.force-quantum 256
But after the recording, there is a big latency in the webcam video recorded. Like 0.5 second. Is there any setting I can tune to reduce the video latency on pipewire ?
