Hello there,

You do need to use the Wowza 4 version. Please contact support@wowza.com for the latest load test tool.

Kind regards,

Salvadore

thx, i’m using version 4 everywhere (client and server Wowza 4.1, loadtool 4.0.1)

Can you please verify that you have copied the contents of the bin, conf, and lib folders from the Load Test Tool download folder to the corresponding Wowza Streaming Engine installation folders.

And that you have run the examples installer in the [install-dir]/examples folder [install-dir]/examples/installall.bat

One other thing that you can try is in your run or debug configuration in eclipse, try adding the following to the VM Arguments on the Arguments tab.

-Dcom.wowza.wms.native.base="win"

If all this checks out and you still get this error, I would suggest you open a ticket with the support team. To do so please zip the following folders and send them to support@wowza.com. Include a link to this thread as a reference:

[install-dir]/conf

[install-dir]/logs

[install-dir]/transcoder

[install-dir]/manager/logs

Thank you.

Salvadore
