What are you trying to do with those libraries?

I use the standard immage of raspberry PI and I am not shure what you mean with repostitories. I do not know how I can find out what the standard repostitories are

My goal is to add vision to my robot and I need I video stream and read it into python3. The plan is :

1-With a cheap web camera that connects to USB video streaming can be done in just a few easy steps, with a Raspberry PI . The simplicity of the solution comes from the streaming technology used effectively. Everything happens over HTTP , so you can watch the Webcam on any device that surfs the web see http://www.talktech.info/2013/01/21/pie ... ng-webcam/

2-Read the frames intp Python and analyse them

It is not new and I do not understand the problem I encounter now

Here is what works to get videodev.h into raspberry pi raspbian for webcam
Posted by Piotrus
http://stackoverflow.com/questions/1569 ... videodev-h



sudo apt-get install libv4l-dev

maybe you will need also:

cd /usr/include/linux
sudo ln -s ../libv4l1-videodev.h videodev.h

run as root without sudo in commands it loads a copy of videodev.h into /usr/include/linux
Whether that then runs ok I do not know yet.
