Stuck on an issue?
Lightrun Answers was designed to reduce the constant googling that comes with debugging 3rd party libraries. It collects links to all the places you might be looking at while hunting down a tough bug.
And, if you’re still stuck at the end, we’re happy to hop on a call to see how we can help out.
Stuttery Clips and Recordings
See original GitHub issueDescribe the bug When reviewing the clips and recordings from cameras, the video is not ‘smooth’; there is some stuttering that can be seen where the video slows for a split second, then quickly speeds up to catch up to the current frame.
5 total high-resolution cameras are in my setup, each 30 FPS. The stuttering can be seen in both highres and lowres streams. I have RTMP re-streams from frigate set for the low-res camera inputs for each. The high-res streams are used for clips, snapshots, and detect (5 FPS as suggested). Nothing else runs on this VM besides rsync backups of clip files every so often. Frigate is connected to home assistant via customer component.
I give a LOT of resources to this VM… 12 CPU cores and 18GB of RAM. I also don’t notice any of this stuttering in the stream direct from the cameras.
Any help in troubleshooting this annoying issue would be extremely helpful. Thank you for this wonderful project it was so easy to get going!

Update: I was able to get smooth video clips after omitting all ffmpeg input args but “- -avoid_negative_ts make_zero”
Edit: forgot to mention that I tested the input parameters directly with ffmpeg copy to drive of the RTMP main stream. I’m pretty confident that this is a ffmpeg issue rather than issue in Frigate.
