Use the self-service troubleshooting tool to quickly diagnose live streaming issues - ApsaraVideo Live

Usage notes

Stream ingest and streaming quality checks support ingest URLs that use the RTMP and ARTC protocols, and streaming URLs that use the RTMP, FLV, HLS, and ARTC protocols. Streaming URLs that use the SRT protocol are not supported.
Stream stuttering and interruption checks support streaming URLs that use the RTMP, FLV, and HLS protocols.
The troubleshooting tool is in private preview. The diagnosis results are for reference only.

Prerequisites

You have generated an ingest URL or a streaming URL. For more information, see Generate ingest and streaming URLs.

Stream ingest/streaming quality checks

Log on to the ApsaraVideo Live console.
In the navigation pane on the left, choose Toolbox > Troubleshooting.
On the Stream Ingest/Streaming Quality Check page, enter the streaming URL that you want to check and click Check.

After the check is complete, resolve any detected exceptions by following the provided suggestions. The following table describes the check items.

Item	Detection Parameters	Description
Domain name check	Domain Name Status	Checks the configuration status of the domain name.

	Stream Ingest Status	Checks whether an active stream is available.
	HTTPS Certificate Note This parameter appears only if the streaming URL uses the ARTC or HTTPS protocol.	Checks the configuration status of the HTTPS certificate for the ingest domain.
	Ultra-Low Latency Stream Ingest Toggle Note This parameter appears only if the streaming URL uses the ARTC protocol.	Checks whether RTS-based stream ingest is enabled or disabled for the ingest domain.
	Quota	Checks the number of used source streams and transcoded streams, and the upper limits for each.
Playback check Note This check item appears only if the domain name is a streaming domain.	Associated Ingest Domain	Checks whether the streaming domain is associated with an ingest domain.
	Stream Ingest Status	Checks whether an active stream is available.
	HTTPS Certificate Note This parameter appears only if the streaming URL uses the ARTC or HTTPS protocol.	Checks the configuration status of the HTTPS certificate for the streaming domain.
	Ultra-Low Latency Live Streaming toggle Note This parameter appears only if the streaming URL uses the ARTC protocol.	Checks whether RTS is enabled or disabled for the streaming domain.
	Auto Transcoding for HTML5 Playback Note This parameter appears only if the streaming URL uses the ARTC protocol.	Checks whether auto transcoding for HTML5 playback is enabled or disabled.

Stream stuttering/interruption checks

Log on to the ApsaraVideo Live console.
In the navigation pane on the left, choose Toolbox.
On the Stream Stuttering and Interruption Check page, enter the streaming URL that you want to check and click Check.
After the check is complete, resolve any detected exceptions by following the provided suggestions. The following table describes the check items.

Item	Detection Parameter	Description
Domain name check	Domain Name Status	Checks the configuration status of the domain name.
	Domain Name Type	Checks whether the domain name is an ingest domain or a streaming domain.
	CNAME Status	Checks whether a CNAME record is configured for the domain name.
Interruption check	Stream Interruption	Checks the number of stream interruptions that occurred in the specified time period and the cause of each interruption.
Stuttering check	Stream Stuttering	Checks the number of stuttering events in the specified time period and the cause of each event.

Streaming fails in a specific region

Issue symptoms

Streaming fails on a large scale in a specific region, such as Yunfu, while it works normally in other regions.

Troubleshooting methods

Check the stream ingest end for errors and verify that it sends data continuously. In particular, confirm whether periodic interruptions occur.
Open the Alibaba Cloud RTS demo page, enter the streaming URL, and test playback.
Click Troubleshoot to obtain the TraceID for end-to-end tracing analysis.

Results differ between cloud providers

Issue symptoms

In the same environment, streaming works normally with another cloud provider but is interrupted on Alibaba Cloud.

Possible cause and troubleshooting recommendations

If the stream ingest end sends no data for more than 10 seconds, the stream may be interrupted. The quality of public network links can also be unpredictable. Before you reproduce the issue, capture packets and retain the complete capture data for in-depth analysis.

An RTMP stream ingest session is interrupted after running for a long time

Issue symptoms

An RTMP stream ingest session runs for more than 10 hours and is then interrupted. The stream does not recover after you restart the camera.

Possible cause and troubleshooting recommendations

The interruption may be caused by a network carrier issue. Contact the carrier to check network connectivity. In addition, capture and analyze packets in the client environment to further identify the cause.
