I have begun developing a set of OctoWS2811 LED Panels that I would like to stream video to via a USB capture device using the v42l library on Ubuntu. I am using Paul S's project as a starting point:
http://www.dorkbotpdx.org/blog/paul/maker_faire_2013
First I would like to get the panel's working using the built in webcam on my laptop, then adapt the software to use the incoming video from the USB capture device instead of the webcam.
My Teensy3.0 is programmed correctly using the VideoDisplay program created by Paul S because I am able to correctly display video on the LED panel using the Processing 2 'movie2serial' Program also created by Paul S.
When I run the 'ledvideo' program on Ubuntu (source code provided by Paul S. at the link above) my webcam is detected, my Teensy3.0 is detected, and the query of the Teensy comes back with the correct data, but the LEDs are not lighting up. After the query response from the Teensy populates Terminal though, it gives me a "not recognized" response, then begins the "........." with the webcam still activated.
Any idea on where I should begin to troubleshoot this issue? I really would like to get this working as it will open up the use of WS2811 panels for me for quite a few projects.
Thank you all for your help!
