playlist reload frequency on live HLS stream excessive

[gmarzot]

I see the release note about aiming to comply with RFC guidance (half target duration i presume). however I am still seeing the playlist loaded many times a second where the target duration is several seconds.

3.0 version of plugin 5.2.1 jmeter java 11 LTS

Hello, thank you to put in contact. I am sorry to hear you are experiencing unexpected behavior.

Can you provide the URL of the master playlist to verify? If the URL is private in some sense, then can you provide the contents of the m3u8 of the master and media playlist files? It would be helpful to get the debug logs of jmeter as well if you can provide them.

If you have any doubts, questions or comments, let us know.

Regards

We identified the root cause of the bug: it is related to interrupting a test and then starting a new one in the same JMeter instance. Can you verify that starting a fresh jmeter instance and not interrupting a plan the playlist reload times are properly working?

We are already working on fixing the above issue. If that is the issue you are experiencing then following release of the plugin should contain the fix. In the meantime, if you interrupt a test, you will need to restart jmeter for playlist reload times to work properly.

Sorry for the inconveniences, and thank you for reporting this bug.

yes - that is in keeping with what i was observing. I discovered that starting the jmeter session over for each run and the issue did not appear. I am seeing a playlist load at a proportional frequency to segment load - more or less 1-to-1. this is fine.
