MediaStream

Constraints for the audio and video components are defined when accessing a MediaStream from the browser.

To define a stream with 1080p constraints for publishing, initialize the Publisher with a mediaConstraint with those video constraints:

const userMedia = {
  video: {
    width: {
      ideal: 1920,
    },
    height: {
      ideal: 1080,
    },
    frameRate: {
      ideal: 60,
    },
  },
}

const rtcConfig = {
  ...config,
  ...{
    mediaConstraints: userMedia,
    bandwidth: {
      video: 2500,
    },
  },
}

const publisher = new window.red5prosdk.RTCPublisher()
publisher
  .init(rtcConfig)
  .then(() => {
    return publisher.publish()
  })
  .catch((error) => {
    console.error(error)
  })
