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.
Main 4:2:2 10 The Main 4:2:2 10 profile allows for a bit depth of 8 bits to 10 bits per sample with support for 4:0:0, 4:2:0, and 4:2:2 chroma sampling. HEVC decoders that conform to the Main 4:2:2 10 profile must be capable of decoding bitstreams made with the following profiles: Monochrome, Main, Main 10, and Main 4:2:2 10. [24] Main 4:2:2 12
On January 15, 2014, oViCs announced the ViC-1 HEVC decoder which supports the Main 10 profile at up to 4K at 120 fps. [90]On February 13, 2014, PathPartner Technology Pvt.Ltd announced HEVC Decoder on ARM Cortex-A Family Processors which takes advantage of the full capabilities of mobile SoCs built on latest ARM processors.
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.
Coding efficiency is the ability to encode video at the lowest possible bit rate while maintaining a certain level of video quality. [2] HEVC benefits from the use of larger CTB sizes. [2] This has been shown in peak signal-to-noise ratio (PSNR) tests with a HM-8.0 HEVC encoder where it was forced to use progressively smaller CTU sizes. [2]
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).

VDPAU was originally designed by Nvidia for their PureVideo SIP block present on their GeForce 8 series and later GPUs. [8]On March 9, 2015, Nvidia released VDPAU version 1.0 which supports High Efficiency Video Coding (HEVC) decoding for the Main, Main 4:4:4, Main Still Picture, Main 10, and Main 12 profiles.
