Details

&keyframerate tells the remote publishers to send keyframes at a specified rate.

Could be useful if packet loss is causing a lot frame corruption.

If you make it less than 1000-ms, you will face a pretty steep drop in video quality.

It may not work at all if set too low; under 500-ms didn't work at all in my testing.

For short random packet loss, test &codec=vp8&vred separately from &keyframe. RED is a negotiation preference for repair payloads; &keyframe asks for new reference frames after damage. They solve different parts of packet-loss recovery, and frequent keyframes can add large bitrate bursts.
