If an error occurs when you use ApsaraVideo Player to play videos, use the single-point tracing feature to locate the cause of the error. The feature allows you to query playback details at the session and user levels and improves the efficiency of playback management by tracing playback exceptions in all links.
Prerequisites
Before you use the single-point tracing feature, make sure that the following conditions are met:
ApsaraVideo Player SDK for Android or iOS V5.4.9.2 or later, or ApsaraVideo Player SDK for Web V2.16.0 or later is integrated. To download the latest version, see Download ApsaraVideo Player SDK.
A valid license is obtained if you use Player SDK for Android, iOS, or Web. For more information, see Obtain a license.
Log reporting is enabled. By default, the feature is enabled in ApsaraVideo Player SDK.
The traceId parameter is passed when you create the player. The traceId parameter is used for user identification. If you do not pass the traceId parameter, you cannot use the single-point tracing feature. For more information about the parameter pass-through method, see Basic features of ApsaraVideo Player SDK for Android, Basic features of ApsaraVideo Player SDK for iOS, and API operations.
The system player, third-party players, and ApsaraVideo Player that is not on an Android, iOS, or web client do not support the single-point tracing feature.
Limits
You can query only the most recent 10,000 sessions. Earlier sessions are not displayed.
You can query only the playback data generated in the last three days.
Procedure
Log on to the ApsaraVideo VOD console.
In the left-side navigation pane, choose Data Center > Single-point Tracing.
Query playback sessions.
In the Enter a traceId field, enter the traceId that you passed when you create the player. This way, you can query playback sessions of a specific user or device.
You can query playback sessions that were created within the last three days and specify conditions such as the time range, file type (on-demand audio and video files or live streams), and status (playback completed, playing, or playback failed) to filter playback sessions.
Click View Details to view the details of the playback session.
