Recorded videos always judder

Describe the bug Frigate itself works great, but all of my recorded videos are juddery. No matter if I play them in the browser or directly the files with VLC or Quicktime. They always run smoothly for 1-2 seconds, then they stall again.

Do I still have an error somewhere in the configuration?

Version of frigate 0.9.0-7b063a1 (same issue with 0.8.4)

I see that those options don’t have the live_flv flag in there, did adding that make any difference for you.

Yes, less stutters. However, the new configuration seems to be even better.

Thank You! Now just need to figure out how to get this working in rpisurv as well!
