On September 26, 2017, Microsoft released Windows 10 Fall Creators Update (version 1709), which removed the out-of-the-box HEVC support, to Windows Insiders. When questioned about the removal, a Microsoft employee claimed that it happened because HEVC (and HEIC) files were only supported by Apple devices. [ 121 ]
The initial HEIF specification already defined the means of storing HEVC-encoded intra images (i-frames) and HEVC-encoded image sequences in which inter prediction is applied in a constrained manner. HEVC image players are required to support rectangular cropping and rotation by one, two, and three quarter-turns.
On June 5, 2017, Apple announced HEVC H.265 support in macOS High Sierra, iOS 11, tvOS, [105] HTTP Live Streaming [106] and Safari. [107] [108] On June 25, 2017, Microsoft released a free HEVC app extension for Windows 10, enabling some Windows 10 devices with HEVC decoding hardware to play video using the HEVC format inside any app. [109]

The HEVC standard defines thirteen levels. [1] [2] A level is a set of constraints for a bitstream.[1] [2] For levels below level 4 only the Main tier is allowed.[1] [2] A decoder that conforms to a given tier/level is required to be capable of decoding all bitstreams that are encoded for that tier/level and for all lower tiers/levels.
Turing – A High Efficiency Video Coding (HEVC/H.265) encoder implemented by BBC Research. libaom – Reference implementation for the royalty free AV1 video coding format by AOMedia, inheriting technologies from VP9, Daala and Thor. Kvazaar – An academic open-source encoder based on the High Efficiency Video Coding (HEVC/H.265) standard.
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
x265 is an encoder for creating digital video streams in the High Efficiency Video Coding (HEVC/H.265) video compression format developed by the Joint Collaborative Team on Video Coding (JCT-VC).
