Encoders

The following encoders are available for playback of a WebRTC-based stream.

Video Encoding Configuration

By not providing the videoEncoding attribute in the WebRTC Subscriber configuration, the server will choose the default encoder to use. If you do not wish for the server to default, you can provide the following values for the property:

• VP8
• H264
• NONE

Audio Encoding Configuration

By not providing the audioEncoding attribute in the WebRTC Subscriber configuration, the server will choose the default encoder to use. If you do not wish for the server to default, you can provide the following values for the property:

• Opus
• PCMU
• PCMA
• Speex
• NONE

VP8

To request VP8 video encoding for playback, provide the VP8 option from the SDK in the intialization configuration for a WebRTC-based subscriber:

var defaultConfiguration = (function (useVideo, useAudio) {
  var c = {
    protocol: getSocketLocationFromProtocol().protocol,
    videoEncoding: red5prosdk.PlaybackVideoEncoder.VP8,
    port: getSocketLocationFromProtocol().port,
  }
  if (!useAudio) {
    c.audioEncoding = red5prosdk.PlaybackAudioEncoder.NONE
  }
  return c
})(configuration.useVideo, configuration.useAudio)
