Update License tracking

UbikLoadPack license format has changed, if you have an old license format (before April 1st, 2024), it is important to upgrade to this version and request a new license file from our support.

Actual live offset is now in Milliseconds

This metric which was previously a number of chunks, has been changed to be a number of milliseconds.

If you manually configure properties, you’ll need to update the following ones :

jmeter.reportgenerator.graph.custom_ulp_actual_live_offset.classname=com.ubikingenierie.jmeter.plugin.videostreaming.graphing.ULPCustomGraphConsumer
jmeter.reportgenerator.graph.custom_ulp_actual_live_offset.title=Actual Live Offset (Distance from Live)
jmeter.reportgenerator.graph.custom_ulp_actual_live_offset.property.set_Y_Axis=Duration in ms
jmeter.reportgenerator.graph.custom_ulp_actual_live_offset.property.set_X_Axis=Elapsed Time (granularity\: ${ULP.overall_granularity_sec}s)
jmeter.reportgenerator.graph.custom_ulp_actual_live_offset.property.set_granularity=${jmeter.reportgenerator.overall_granularity}
jmeter.reportgenerator.graph.custom_ulp_actual_live_offset.property.setSampleVariableName=ulp_actual_live_offset

Bug fixes

  • Dash : URI formation for time sync using the UTCTimingElement is incorrect if no BaseURL is present

  • VOD : Keep Init segment if offset is used

Java version

Note that this version now requires Java >=11 and supports LTS versions :

  • Java 11
  • Java 17
