V4l2 linux 11. Especially the fact that V4L2 drivers have to setup supporting ICs to do audio/video muxing/encoding/decoding makes it more complex than most May 21, 2020 ยท Linux Video4Linux2 API (v4l2) ¶ Video4Linux or V4L is a collection of device drivers and an API for supporting readltime video capture on Linux systems. It provides helper functions and a common application interface specified in this document. 7. When an application makes a driver call, control passes first to the videodev method, which translates the file and/or inode structure pointers into the corresponding V4L2 structure pointer, and calls the V4L2 Early drivers used ad-hoc interfaces. 18. Introduction ¶ The V4L2 drivers tend to be very complex due to the complexity of the hardware: most devices have multiple ICs, export multiple device nodes in /dev, and create also non-V4L2 devices such as DVB, ALSA, FB, I2C and input (IR) devices. The API was revised again in 2002 prior to its inclusion in Linux 2. The driver modules plug into the videodev kernel module.
