Editing FFmpeg (section)

=== Special purpose hardware ===
There are a variety of [[Application-specific integrated circuit|application-specific integrated circuits (ASICs)]] for audio/video compression and decompression. These ASICs can partially or completely offload the computation from the host CPU. Instead of a complete implementation of an algorithm, only the [[API]] is required to use such an ASIC.<ref>{{cite web |url=https://trac.ffmpeg.org/wiki/HWAccelIntro |title=FFmpeg Hardware Acceleration |publisher=ffmpeg.org Wiki |access-date=2016-11-12 |archive-date=2016-12-04 |archive-url=https://web.archive.org/web/20161204005157/http://trac.ffmpeg.org/wiki/HWAccelIntro |url-status=live }}</ref>

The following APIs are also supported: [[DirectX Video Acceleration]] (DXVA2, Windows), [[Direct3D 11]] (D3D11VA, Windows), [[Media Foundation]] (Windows), [[Vulkan]] (VKVA), VideoToolbox (iOS, iPadOS, macOS), RockChip MPP, [[OpenCL]], [[OpenMAX]], MMAL (Raspberry Pi), MediaCodec ([[Android (operating system)|Android OS]]), V4L2 (Linux). Depending on the environment, these APIs may lead to specific ASICs, to [[GPGPU]] routines, or to [[SIMD]] CPU code.<ref name="HWAccelIntro">{{cite web |title=HWAccelIntro – FFmpeg |url=https://trac.ffmpeg.org/wiki/HWAccelIntro |website=trac.ffmpeg.org |access-date=2016-11-12 |archive-date=2016-12-04 |archive-url=https://web.archive.org/web/20161204005157/http://trac.ffmpeg.org/wiki/HWAccelIntro |url-status=live }}</ref>
