ApsaraVideo VOD:Playback Quality Monitoring (legacy)

Last Updated:Jun 10, 2026

Track video playback quality and viewer engagement through the ApsaraVideo Player SDK. Key metrics include playback failure rate, first frame time, and buffering rate.

Important

Deprecation notice: Alibaba Cloud has deprecated this feature. The upgraded Playback Quality Monitoring (New) supports multi-dimensional metrics (buffering rate, network latency, playback success rate) with improved data visualization.

Metrics

QoS metrics

Quality of Service (QoS) metrics measure the playback quality of your application.

Metric

Calculation

Description

video views

Total playback initiations through the ApsaraVideo Player SDK.

A view is counted when your application first calls theprepare method to start playback. Resuming via theplay method after a pause or looping does not count.

actual views

actual views = Total video views - Total playback failures - Total startup bounces

Startup bounces are typically negligible.

first frame time (ms)

Time from playback request to first frame render.

Not recorded if playback fails to start.

QoE metrics

Quality of Experience (QoE) metrics measure user viewing behavior in your application.

Metric

Calculation

Description

visitors

Active users of your application using the ApsaraVideo Player SDK. On mobile clients, users are identified by device ID.
