The Video for Linux Test Environment is a software tool designed to test and verify the compatibility and functionality of devices with the Video for Linux driver framework. It supports various V4L2 devices and provides an environment for conducting automated and manual tests.
If you are looking for a test environment to evaluate Video for Linux API based Linux kernel drivers, v4l-test may be the solution you need. This software runs in userspace, imitating regular video applications, and performing tests on error handling mechanisms of a V4L2 driver. These evaluations come in the form of "invalid test cases".
Getting started with v4l-test is a straightforward process. You just have to make sure that you have a C compiler, the CUnit development files, and "make" installed on your system. Once you have these requirements, simply type "make" to build the test environment.
To run the software, you need to have a video device connected to your system and accessible under /dev/video0. This device can be a webcam or a tuner card, for instance. However, even if you don't have any hardware device available, you can still use the "Virtual Video Driver" to test v4l-test. To compile this driver, you first need to configure your kernel with CONFIG_VIDEO_VIVI=m, following this path:
Device Drivers
-> Multimedia devices
-> Video For Linux
-> Video capture adapters
-> Virtual Video Driver
Once you have compiled the Virtual Video Driver, you can execute v4l-test and start your evaluations.
