PreCallVideoQuality

Video measurements for one direction. The uplink fills bytesSent and qualityLimitationReason; the downlink fills bytesReceived and the frame-drop and freeze fields. Everything belonging to the other direction is null.

Properties

bitrate

val bitrate: Long?

Bits per second.

bytesReceived

val bytesReceived: Long?

Video bytes received over the whole sampling window; null on the uplink.

bytesSent

val bytesSent: Long?

Video bytes sent over the whole sampling window; null on the downlink.

fps

val fps: Long?

Frames per second actually sent or received, which may be below what was captured.

framesDropped

val framesDropped: Long?

Frames thrown away before display. Downlink only.

framesDroppedRatio

val framesDroppedRatio: Double?

framesDropped as a percentage of the frames received. Downlink only.

freezeCount

val freezeCount: Long?

How many times the picture froze. Downlink only.

jitter

val jitter: Long?

Arrival jitter, ms. Video starts to suffer from about 70 ms.

packetLoss

val packetLoss: Double?

Lost packets as a percentage. Video tolerates more than audio, up to about 4%.

quality

val quality: Int

Video on the 0-5 scale. 0 means not measured.

qualityLimitationReason

val qualityLimitationReason: String?

Why the encoder sent less than it captured — "bandwidth", "cpu", "none". Uplink only; the single best clue that this device, not the network, is the limit.

resolution

val resolution: String?

The resolution that was sent or received, e.g. "1280x720".

rtt

val rtt: Long?

Round-trip time, ms. Counted against the score above roughly 200 ms.

totalFreezesDuration

val totalFreezesDuration: Double?

Seconds the picture was frozen in total. Downlink only.
