Description

Describe the bug While playing videos, there's a general jerkiness every few seconds.

To Reproduce Steps to reproduce the behavior:

  1. Configure a CPU-optimized Digital Ocean droplet with 8Gb of RAM in your closests datacentre
  2. Install Neko as per instructions
  3. Log in, go to this trailer, play it, full screen it, full screen your browser.
  4. Note the jerking every few seconds, with jerking and tearing particularly noticeable in camera pans

Expected behavior Video playback as smooth as a baby's bum

Desktop (please complete the following information):

  • OS: MacOS
  • Browser: Chrome, Safari
  • Version FF 74.0, Chrome 80.0.3987.149

Additional context I'm not sure if this is a problem with X11, or X11VNC but I've tried on different systems with different browser combinations and it's consistent. Happy to look into it if someone can give me some pointers.

CPU load is fine, RAM is fine. There could be a sync and framerate issue or something can't keep up.

Contributor guide

Research direction
Inspect the RTC stream handling code for frame drops or synchronization issues. Trace the video pipeline from X11 capture to WebRTC encoding.
