Jetson Linux Api Reference 12 Camera V4l2 Cuda Camera Capture Cuda Processing Nvidia Docs From this talk, you will learn how to move video data from a video for linux (v4l2) camera into the gpu on an nvidia jetson system on chip. you will see how to process that data on the. As shown in the following diagrams, the buffer flow differs depending on v4l2 capturing modes and cuda memory management. v4l2 memory mapped buffers (v4l2 memory mmap) are allocated in kernel space. the application maps them in user space and copies them to the cuda device allocated memory for cuda processing.
Jetson Multimedia Api Samples 12 Camera V4l2 Cuda Camera V4l2 Cuda Cpp At Master Ald2004 Hi, please upgrade to jetpack 5.1.1 and make sure you can successfully run 12 camera v4l2 cuda sample first. Contribute to ald2004 jetson multimedia api development by creating an account on github. Jetpack includes jetson linux with bootloader, linux kernel, ubuntu desktop environment, and a complete set of libraries for acceleration of gpu computing, multimedia, graphics, and computer vision. The video cuda encoder sample demonstrates how to capture use libv4l2 api to encode h.264 h.265 video streams. before beginning encoding, it uses the nvidia ® cuda ® api to render a black rectangle on the input yuv image data; the same buffer is used and shared by the decode component.

Doing some video processing, the frame rate is too low for what i am doing. so, i would like to know if it is possible to add the gpu to the v4l2 to speed up the processes. Python v4l2capture is a slim and easy to use python extension for capturing video with video4linux2. it supports libv4l to convert any image format to rgb or yuv420. This sample demonstrates how to capture images from a v4l2 yuv type of camera and share the image stream with nvidia ® cuda ® engines to draw a black box on the upper left corner.
