Use v4l2-ctl utility tool to capture from the camera. As a kernel driver, it should be faster than the user space driver.įinally, V4L2 was released under the name bcm2835-v4l2 which is included Raspberry Pi OS by default. Recognizing that a V4L driver is needed, the Raspberry Pi Foundation reported that they were working with Broadcom to develop an official kernel V4L driver. An independent developer has now written a user space V4L driver for the Raspberry Pi camera, but it is closed sourced, and can be a little slow because it runs as a user program rather than a kernel driver. Under Linux, the standard APIs for cameras (including webcams) is V4L (Video for Linux), and a number of applications have been written that support any camera with a V4L driver. Raspicam commands has a set of tools to work with the camera module: raspistill, raspivid, and raspiyuv.
