I don't configure my system(s) daily to remember such things. ;) Quick Sync Video is exposed via MediaSDK (high-level) and libva (low-level). MediaSDK hasn't been ported yet but media-driver (its backend) has. FFmpeg and GStreamer support both MediaSDK and libva. > 1. DRM module loaded > 2.

Try both. ;) Some examples from https://trac.ffmpeg.org/wiki/Hardware/VAAPI don't work on iHD e.g., "Burn subtitles into the video while transcoding". i965 (libva-intel-driver) advantages: - VP8 encoding on Skylake - Partial VP8 encoding on Haswell/Broadwell - Partial VP9 decoding on Haswell/Broadwell/Skylake - H264 encoding profiles for Multiview and Stereo iHD (libva-intel-media-driver) advantages: - Decoding on console framebuffer (e.g, mpv --gpu-context=drm) - Better encoding performance (even without MediaSDK) - FEI (Flexible Encoding Infrastructure) for HEVC - JIT (Just-In-Time) compilation of media kernels (needs intel-graphics-compiler) - Icelake support (and maybe Xe in future) - Actively developed upstream
