Due to the growing popularity of portable multimedia display devices and wide availability of high-definition video
content, the transcoding of high-resolution videos into lower resolution ones with different formats has become a crucial
challenge for PC platforms. This paper presents our study on the leveraging of the Unified Video Decoder (UVD)
provided by the graphics processor unit (GPU) for achieving high-speed video transcoding with low CPU usage. Our
experimental results show off-loading video decoding and video scaling to the GPU can double transcoding speed with
only half the CPU usage compared to in-box software decoders for transcoding 1080p (1920x1080) video content on an
AMD Vision processor with an integrated graphics unit.
