Using Cherrypy with Odroid setup (Red Balloon Experiment)

Archive

I am trying to replicate the Red Balloon Experiment and I have installed and gotten connection with MAVlink successfully. However on boot-up of Odroid I now see the following:

[code]starting web server
CherryPy Checker:
The Application mounted at ‘’ has an empty config.

I’m not sure what those ‘Invalid argument’ errors are at all. The blue lights on my Logitech C920 webcam go on, but I am really stuck on how to check that the video feed is working. I have tried ‘screen -x’ but I only see the MAVlink dialog, no video feed.

I am new to Cherrypy and any help would be greatly appreciated!

I should add this (I cannot edit for some reason) that I am trying to access localhost:8080/ and it isn’t working. I have checked my used ports in cmd prompt and 8080 is not being used.

I have also enabled the logging script and it says the following on bootup:

[code]CherryPy Checker:
The Application mounted at ‘’ has an empty config.

[24/Aug/2015:05:11:11] ENGINE Bus STARTED

[/code]

The rest is the same as the above code I posted.

Ok I have solved the problem viewing the frame in the web-browser, I missed that my code said ‘8081’ not ‘8080’ and fixed this.

But the webcam itself is not working, hence the above errors ‘VIDIOC_QUERYMENU: Invalid argument’

The frame in the web-browser is black.

Well I resolved the issue so this can be closed. If anyone wants to know more please do ask I will be happy to provide info.
