Systems and methods are provided for efficient screen capture and video recording on mobile and other devices. The video is recorded using a graphics rendering pipeline that includes a primary frame buffer, a secondary frame buffer, and a video writer module that encodes and writes data to a video file. The frame buffers include multiple textures to which graphics data can be rendered or copied, with at least the secondary frame buffer textures backed with memory that is quickly accessible by a central processing unit. In operation, a frame is rendered into a texture in the primary frame buffer, and the contents of the rendered frame are copied to a texture of the secondary frame buffer as well as to a default graphics rendering pipeline for output to a display. The contents of the rendered frame are then provided from the secondary frame buffer to the video writer for output to a video file.
