This generic video API can be used to capture/output video frames. Once a video buffer is enqueued to a video device endpoint, device owns the buffer and can process to capture (camera), output (disk, display), convert (hw encoder)... User can then call dequeue to retrieve the processed buffer (video driver ensure cache coherency). Once dequeued, video buffer is owned by user (e.g. for frame processing, display buffer update, write to media, etc...). For each video-buffer, user needs allocate the associated frame buffer via video_buffer_alloc. Buffer format is defined by video device endpoint configuration. Video device can be controlled (e.g. contrast, brightness, flip...) via controls. Signed-off-by: Loic Poulain <loic.poulain@linaro.org>
