Unable to start WebGUI

[agrosjea]

Hi !

Linux version : Mint 17.3 Cinnamon 64-bits
Kernel : 3.19.0-32-generic

I wanted to test liveMediaStreamer and its WebGUI and after clicking the start button, I get the following error :

Error: "Error processing internal event. Invalid action..."

Here is the rackup console output :

Hi arnaud,

I am sorry the documentation might be a bit confusing some times. Anyhow, the first thing to do, which is not documented and it doesn't happen by default, is to use the master branch of the livemediastreamer and master branch of the livemediastreamerwebgui. If both are not in the master branch it will not work. I think this is your problem.

Livemediastreamer master branch is outdated a bit, we have not merged it to master because we have not updated and maintained the webgui repository.

Please don't hesitate to contact us for any further doubt.

Hello David !

I tried again with master branches and got the following message after clicking start :
