Hi,  
I have a webinar application that allows the sender to share screen and open camera at the same time. I created two producers, one for sharing screen and other for camera. I modified the initialAvailableOutgoingBitrate and maxIncomingBitrate but I noticed that these values are distributed over the both produces.  
Can I set these values for each produces or fix a bitrate for share screen and camera.  
Thanks,

In mediasoup-client you can set the `maxBitrate` of each Producer’s `encoding`, and also change it later via `producer.sender.setSettings()`, but that’s WebRTC 1.0 API since `producer.sender` returns the `RTCRtpSender`.

I’m using SVC. I tried it on chrome and watch webrtc internals I noticed that it has no effect. this is my code:  
screenStream = await getUserMedia(producerLocalTransport, ‘screen’);  
const track = screenStream.getVideoTracks()[0];  
const params = { track, appData : { mediaType : ‘screen’ }};

```
	      params.encodings = [
	        { maxBitrate: 100000 }
	      ];
	

	    screenProducer = await producerLocalTransport.produce(params);
```

Try calling producer.sender.setSettings() later as I said.

I used this and it worked setRtpEncodingParameters({ maxBitrate: 100000 })

I had an error with setRtpEncodingParameters on firefox. Where can I call producer.sender.setSettings() on client or server? I didn’t find’t this function.

Please read the official WebRTC 1.0 API and the methods of RTCRtpSender:
