  • BroadcastQuality represents the quality of the stream based on the bitrate minimum and maximum provided on session configuration. nearMinimum means the stream is near the lowest possible quality (the configured minimum bitrate), or streaming is not possible at all. nearMaximum means the bitrate is near the maximum allowed (the configured maximum bitrate).

    If the video configuration looks like: initial bitrate = 1000 kbps minimum bitrate = 300 kbps maximum bitrate = 5,000 kbps It will be expected that a nearMinimum quality is provided to this callback initially, since the initial bitrate is much closer to the minimum allowed bitrate than the maximum. If network conditions are good, the quality should improve over time towards nearMaximum.

    Swift

    @frozen enum BroadcastQuality : Int, @unchecked Sendable

  • NetworkHealth represents the current health of the network. bad means the network is struggling to keep up and the broadcast may be experiencing latency spikes. The SDK may also reduce the quality of the broadcast on low values in order to keep it stable, depending on the minimum allowed bitrate in the broadcast configuration. A value of excellent means the network is easily able to keep up with the current demand and the SDK will be trying to increase the broadcast quality over time, depending on the maximum allowed bitrate. Values like medium or low are not necessarily bad, it just means the network is being saturated, but it is still able to keep up. The broadcast is still likely stable.
