Intel® Quick Sync Video technology on Iris® Pro graphics and Intel® HD Graphics provides transcode acceleration on Linux* systems in FFmpeg* 2.8 and later editions. This paper is a detailed step-by-step guide to enabling h264_qsv, mpeg2_qsv, and hevc_qsv hardware accelerated codecs in the FFmpeg framework.
Performance note: The *_qsv implementations are intended to provide ...easy access to Intel hardware capabilities for FFmpeg users, but are less efficient than custom applications optimized for Intel® Media Server Studio.
