High WebRTC Encoding Latency & Frame Drops on Radxa 4D (RK3576) with Twilio SDK

Hey everyone,

I’m having some trouble with video calling on my Radxa 4D and could use some help.

I’m using the Twilio video sdk and a patched version of chromium so that hardware acceleration is working. Even though it’s “working”, my encoding latency is really high anywhere from 18ms to 30ms per frame. I’m also seeing a lot of random frame drops.

For a chip like the RK3576, this feels a bit slow. Has anyone else used the Radxa 4D for webrtc ? I’m wondering if there are specific settings or flags I should be using in Chromium or Twilio to get that latency down and stop the frame drops.
