Troubleshooting

Ant Media Server

I see High CPU Usage.

Please get Thread Dump by using the following REST methods: GET http://AMS_URL:5080/rest/threads-info GET http://AMS_URL:5080/rest/thread-dump-json GET http://AMS_URL:5080/rest/thread-dump-raw You can easily call these methods via the browser address bar since all of them are GET methods.

Check whether there exists a dead-locked-thread by the threads-info method.

Check blocked time of the threads got by thread-dump-json method.

For more details, analyze threads by loading the raw dump file by the VisualVM tool.

I see High Memory Usage.

Please get Memory Dump by using the following REST method: GET http://AMS_URL:5080/rest/heap-dump You can easily call this method via the browser address bar since all of it is a GET method.

Load the created heapdump.hprof file bt the VisualVM tool and make memory analyze.

Check for any leaks. You can also use Eclipse Memory Analyzer Tool tool to find leaks automatically.

I get notSetRemoteDescription error.

Your device may not have the necessary h264 codec. Check your device codec compatibility from: https://mozilla.github.io/webrtc-landing/pc_test_no_h264.html

I send a stream to the server with RTMP but I can't play the stream with WebRTC player?

This issue( "NoStreamExist") due to your sending stream resolution is not enough for the configured Adaptive Bitrate values.

In WebRTC side, you can check your camera resolution capacity in below links: https://webrtchacks.github.io/WebRTC-Camera-Resolution/ https://webrtc.github.io/samples/src/content/getusermedia/resolution/

In RTMP side, you need to check your Video Resolution(Output Resolution) setting values in OBS Video section as an image -> https://imgur.com/a/JlVv04h Your Output resolution size should be high than your Adaptive Streaming setting.

If you want to stream 720HD, you need to provide the requirements at least 720p.

Be sure about video resolution in your adaptive settings is equals and less than the stream you send.

I can't start autoplay in Google Chrome & Mozilla Firefox?
