Functions

func AudioTrackScore added in v1.1.0 

func AudioTrackScore(params TrackScoreParams, normFactor float32) float32

func Score2Rating 

func Score2Rating(score float32) livekit.ConnectionQuality

func ScreenshareTrackScore added in v1.1.0 

func ScreenshareTrackScore(params TrackScoreParams) float32

rtcmos gives lower score when screen share content is static. That is due to use of bits / pixel / frame in the model. Even though the frame rate is low, the bit rate is also low and the resolution is high. Till rtcmos model can be adapted to that scenario, use loss based scoring.

func VideoTrackScore added in v1.1.0 

func VideoTrackScore(params TrackScoreParams, normFactor float32) float32
