HEVC/H.265 - Hardware/Software/Boxes and Console Support

HEVC, or High Efficiency Video Codec, is also known as H.265, or MPEG-H Part 2, as a true successor to H.264.

H.265 - Why Better Than H.264

HEVC’s main advantage over H.264 is that it offers roughly double the compression ratio for the same quality. This means that a video file encoded with HEVC can occupy half the space of its H.264 equivalent with no noticeable change in quality, or the same amount of space with improved quality. Sounds pretty good, right?

HEVC is able to compress files to a greater extent than before by evolving upon the H.264 standard. In both of these standards, motion compensated prediction is used to find areas that are redundant within a single frame or in the frames that follow. When redundant blocks of pixels are identified, they are encoded by referencing another area in the same or following frames. In H.264, these blocks can be up to 16x16 pixels in size, but big gains in compression were made by increasing this to 64x64 in HEVC.

Other improvements also help HEVC achieve greater levels of compression, including better variable-block-size segmentation, improved deblocking and motion compensation filters, sample adaptive offset filtering, and better motion vector prediction and precision. This page here from the x265 group has a great explanation of these terms and how it can improve HEVC’s efficiency.

H.265 - Hardware Support


Here’s a quick rundown of well-known hardware that includes dedicated HEVC decoding blocks, which definitely support efficient HEVC playback:

 Intel 6th-generation ‘Skylake’ Core processors or newer

 AMD 6th-generation ‘Carizzo’ APUs or newer

 AMD ‘Fiji’ GPUs (Radeon R9 Fury/Fury X/Nano) or newer

 Nvidia GM206 GPUs (GeForce GTX 960/950) or newer

 Other Nvidia GeForce GTX 900 series GPUs have partial HEVC hardware decoding support

 Qualcomm Snapdragon 805/615/410/208 SoCs or newer. Support ranges from 720p decoding on low-end parts to 4K playback on high-end parts.

 Nvidia Tegra X1 SoCs or newer

 Samsung Exynos 5 Octa 5430 SoCs or newer

 Apple A8 SoCs or newer

 Some MediaTek SoCs from mid-2014 onwards

As you can see, most desktop hardware released in 2015, and most mobile hardware from late 2014 onwards, supports dedicated HEVC playback.

If you have a computer or device that support HEVC encoding, why not backup your Blu-ray and DVD collcetions into HEVC codec, please turn to: How to Encode Blu-ray and DVD to H.265 Videos with Handbrake, enable you manage your Blu-ray movies, DVD movies, videos easier.

In additional, you can also store your Blu-ray movies, DVD movies, videos to NAS or Cloud with H.265 codec for playing on network media players/Media Streamers, Smart TVs, network-enabled Blu-ray Disc players. Read More: NAS vs Cloud | Which one Better for Backuping Blu-ray / DVD / Videos.

H.265 - Software Support


As for software that can playback HEVC-encoded files, there are many options out there. On Windows 10, you can natively play HEVC videos in the default Films & TV app or through Windows Media Player. Alternatively, you can use VLC or MPC-HC for playback, which support older operating systems, or popular media center apps like Kodi (version 14 onwards) and Plex Media Player.

If you’re running macOS or iOS, VLC is your best bet. On Android devices, you’ll be able to play back HEVC files using MX Player through software decoding if your device is fast enough, or if it is, both MX Player and the Plex app supports native HEVC playback. 

H.265 - Streaming Boxes and Console Support


Here’s a quick rundown of popular media playing devices that don't support HEVC:

 Google’s Chromecast (first and second generations)

 Apple TV (although some reports suggest 1080p HEVC playback is possible by running VLC on a 4th-gen model)

 Roku (third-gen models and earlier)

 Amazon Fire TV (2014) and Fire TV Stick

 Any Western Digital WD TV products

 All PlayStation consoles (including PS4 Pro)

 Xbox 360

And here are the media players that do support HEVC:

 Roku 4

 Amazon Fire TV (2015) and 2nd-gen Fire TV Stick

 Xbox One

This isn’t an exhaustive list, but you can clearly see that there’s just a handful of very recent devices that support native HEVC playback. The Xbox One is the only console to support playback, although support for HEVC was added through a software update, presumably utilizing software decoding.

So while the benefits of HEVC encoding are clear, playback is essentially restricted to PCs, high-end smartphones and tablets, and a very small range of media players and consoles.
