v4l-test For Linux

v4l-test is a test environment of Video for Linux API based Linux kernel drivers. This test environment is running in userspace and tries what normal video application would do. It also tries some things which are supposed to test the error handling mechanisms of a V4L2 driver. These are the "invalid test cases".

To build the test environment you will need a C compiler, "make" and the CUnit development files installed. Just type "make" and the test environment is ready.

You need to have a video device (i.e. webcam, tuner card, etc.) connected to your system and available under /dev/video0. If you don't have any hardware device available, you can still test the "Virtual Video Driver". To compile this you need to compile your kernel with CONFIG_VIDEO_VIVI=m under:

-> Device Drivers     -> Multimedia devices       -> Video For Linux         -> Video capture adapters          -> Virtual Video Driver

At this point you can execute v4l-test.
