We present an accelerated implementation of high-speed video stream encoder for the H.264 digital video codec standard. Based on the parallel processing techniques with GPU’s, we used an OpenCL-based GPU kernel programs. We achieved a high-level CPU-GPU interoperability, through making CPU perform all input/output operations and overall stream control, while GPU does the core encoding operations. Our final result shows remarkable speed-up in comparison with the previous implementations.
