Adding delay/buffer at client end, while receiving live stream.

[hemant vyas]

Hello All,

I have a live audio streaming application, I want to add some buffer at client end so that in case of network spikes the audio is smooth.

Till now i found that 'playoutDelayHint' this property can be used, Let me know if i am wrong.

I have tried to add below code but its not working.(Both the console.log are printing)

          this.webRtcPeer = new kurentoUtils.WebRtcPeer.WebRtcPeerRecvonly(options,

            error => {

              if (error) {

                return console.error(error);

              }

              this.webRtcPeer.generateOffer((a, b) => this.onOffer(a, b));

              console.log("################ Adding 10 sec delay");

              this.webRtcPeer.peerConnection.getReceivers().forEach(function (sender) {

                sender.playoutDelayHint = 10;

                console.log("################ ADDED 10 sec delay");

              }); 

            });

I also tried to do this with below code (Still no luck):

const [audioReceiver, videoReceiver] = this.webRtcPeer.peerConnection.getReceivers();

          // Add additional 500 milliseconds of buffering.

          setInterval(async () => {

            audioReceiver.playoutDelayHint = audioReceiver.jitterBufferDelayHint = 100;

          }, 1);

Please find a working example here if that may help: https://jsfiddle.net/75cnfojy/

I don't know about this property, but here I found some discussion about it:

https://groups.google.com/g/discuss-webrtc/c/wtuhQu6c1KY

it includes a small demo for audio:

All I can say is that it is working for me, check this demo:
https://murillo128.github.io/web-audio-rtc-test/ right channel is
delayed via web audio and left channel is delayed via playoutDelayHint

I tried the same, still no luck.

  public testDelay() {

    setInterval(async () => {

      this.webRtcPeer.peerConnection.getReceivers()[0].playoutDelayHint = 1000;

      // this.webRtcPeer.peerConnection.getReceivers()[0].minPlayoutDelay = 3;

      // this.webRtcPeer.peerConnection.getReceivers()[0].maxPlayoutDelay = 10;

      console.log("Setting delay...");

    }, 1);

  }
