Now there are 2 solutions, please try both and tell me which one you think is the best!! The sources will be saved into a folder called "Trunk" in the path from where you run the previous command.

Sudo apt-get install subversionand now you can download the sources: Now you need to donwload the UVCVIDEO driver sources, but they are on a SVN repository, so you need to install the SVN client: Otherwise, your camera needs to use propertary driver, because it doesn't use standard protocol/command. If your webcam passes this test, you can go on reading. If you get something like the following, your webcam is UVC capable:
Sudo lsusb -d xxxx:yyyy -v | grep "14 Video" In order to know if your webcam is UVC capable you just need to open your shell and run:īus 001 Device 002: ID xxxx:yyyy "Your_Webcam_Model"īus 001 Device 001: ID 0000:0000Then type: This help is intended only for those who have a UVC capable webcam.īut it will be usefull only if your webcam supports YUV image format and the applications that use your webcam request YUV format to your webcam!!! I've tested it and it works with: It's a very quick how-to that will help you to solve the problem of those webcams who give back upside-down images/videos!!!
