Abstract: A device for recording videos includes an image signal processor to process frames captured in response to a request for recording a video at a first frame rate, and a video encoder to encode captured frames. The device also includes processing circuitry operative to allocate image buffers from memory in response to the request, and execute a camera software to direct the image signal processor to fill each image buffer with a batch of the captured frames. For each filled image buffer, a reference of the image buffer is passed from the camera software to a video software at a second rate, which is a fraction of the first frame rate. The processing circuitry then executes the video software to provide one frame at a time to the video encoder for encoding at the first frame rate.
