Abstract
In this demonstration, we showcase a complete software encoding and decoding solution for the new High Efficiency Video Coding (HEVC) standard. The encoder is optimized for x86 processors using SSE instruction set extension and multi-thread technology, and achieves high efficiency at a significantly reduced computation load. We have integrated the encoder library into the widely-used media framework FFmpeg and developed transcoding and recording applications for HEVC. The decoder is highly optimized for both x86 and ARM architecture. With novel single-instruction-multiple-data (SIMD) algorithms and a frame-based parallel framework for multi-core CPUs, decoding speed of 46FPS for 1080p videos on ARM Cortex-A9 1.5GHz dual-core processor and 75FPS for 4K (3840x2160) videos on Intel i7-2600 3.4GHz quad-core processor can be achieved. We have also integrated the decoder library into FFmpeg and made an Android video player based on that. The software solution can well meet the demand of producing and watching HEVC videos on existing devices, showing promising future of HEVC applications.
