(integer value)	bitrate in kbps

Details

&videobitrate sets the target video bitrate of a video feed in a solo link or the video feeds in a scene.

For rooms, use &totalroombitrate / &trb when you specifically want to control guest-to-guest room viewing quality. If &totalroombitrate is not set on a room link, &videobitrate can be used as that guest's initial total room bitrate target.

If the sender uses &outboundvideobitrate, that sets the default target bitrate on the push side. A viewer-set &videobitrate overrides that default. A sender-side &maxvideobitrate still caps the maximum bitrate, regardless of what the viewer requests.

In some cases, &videobitrate is enforced via SDP munging, so it can also act as a maximum cap depending on browser/negotiation.

Default value will target around 2500-kbps.

The maximum achievable bitrate is around 60,000-kbps (60-mbps).

Lowering the bitrate can sometimes reduce CPU load, bandwidth, and stuttering issues

Camera-video targets of 600-kbps or lower intentionally enable bitrate-based resolution scaling, reducing encoder work and CPU usage as well as bandwidth. For example, a 1280x720 source may be reduced to about 640x360 at 600-kbps; lower targets can scale it down further. At 601-kbps and above, this particular bitrate-based resolution reduction is removed, although other resolution and congestion limits can still apply.

You might want to increase the bitrate for game streams, to ensure smooth frame rates.
