How to Optimize Video quality for bandwidth#

Often times, bandwidth is unpredictable. Bandwidth congestion can occur when user suddenly starts a streaming service or download a file from the internet. Sudden hike in the bandwidth usage may cause network congestion and results in poor meeting experience. Optimizing video quality for available bandwidth is very important for ensuring quality meetings.

HDmeet SDK provides 3 different quality levels (streams) for remote participants video quality

At any time, client can send below message to switch between video quality Sample message :

meetingsession.remoteParticipantVideoQuality([participant_id], bit_rate, quality)

Another use case can be client application can be of different UI. For eg, your application might have a speaker only view where you show only the person who speaks and other videos are hidden from the view. In another case you might wanted to show video of all participants. Pausing and resuming a video stream is a life saver here.

Hoolva SDK support pausing a video stream and resume the stream functionality. Client can use :

meetingsession.pauseSubscriberVideo([participantID_1,participantID_2],true) //for pause

meetingsession.pauseSubscriberVideo([participantID_1,participantID_2],false) //for unpause

Bandwidth optimization is current not supported in react-native sdk

How to start a screen share in the meeting#

Once the user is in the meeting he can initiate screen share with the below message

meetingsession.contentShareAction(audio, video, options)

To stop a screen share session, client should send audio:false and video:false

Audio only sharing is currently not supported in this version of the SDK which means, video:false and audio: true combination won’t work at this time.

For electron, we have to follow the below steps as well.

// In the main process.
const { desktopCapturer } = require('electron')
desktopCapturer.getSources({ types: ['window', 'screen'] }).then(async sources => {
  for (const source of sources) {
    if (source.name === 'Electron') {
      mainWindow.webContents.send('SET_SOURCE', source.id)
      return
    }
  }
})

Screen sharing is not supported in this version of react-native sdk
