Intel Quick Sync Video (QSV)¶
Definition¶
Quick Sync Video (QSV) is Intel's integrated hardware media engine present on most modern Intel client and server CPUs (inside the integrated GPU / iGPU portion of the die). Provides hardware-accelerated video encode/decode for codecs including H.264, HEVC, and AV1 (on newer generations).
Stub page — named in sources/2026-03-09-meta-ffmpeg-at-meta-media-processing-at-scale as one of the hardware-accelerator classes exposed through FFmpeg's standard hardware-accelerated video codec API, alongside NVIDIA NVDEC/NVENC, AMD UVD, and Meta's internal MSVP.
Role in FFmpeg¶
QSV is a software-host-adjacent accelerator: the iGPU sits on the same silicon as the CPU, so data paths between general-purpose code and the media engine are short and cheap. For fleet-class transcoding without discrete GPUs, QSV is the standard acceleration target.
