DivX HEVC Hardware Acceleration: Test Results on Intel Skylake

Enabling DivX Accelerated Options

The DivX Accelerated program vigorously tests and validates that a particular chipset is optimized for decoding and/or encoding of DivX video formats in DivX Software. Until now, DivX Software has offered DivX Accelerated functionality for encoding and decoding of AVC video (H.264/MKV and MP4) and decoding of AVI video (DivX/MPEG-4 ASP).

As of the DivX 10.4 software release, Intel® Quick Sync Video has been enabled natively to the new DivX Player to enable hardware accelerated decoding of HEVC video on computers with supported Intel chipsets. You can enable the DivX Accelerated option in Player’s Preferences.

This is a significant milestone to improve the experience of playing HEVC video, especially at high resolutions like 4K. This experience is particularly improved on the newly released 6th Generation Intel Core processor family (“Skylake”), which uses the dedicated media processing capabilities of Intel Graphics Technology.

The 4th and 5th Generations Intel Core Processor families (“Haswell” and “Broadwell”) offer a form of improved HEVC video playback through partial hardware acceleration support. However, the 6th Generation Intel processors offers full fixed-function decode through Intel® Quick Sync Video that offers high performance decode while also enabling the processor to complete other tasks, improving overall PC performance and responsiveness.

Our preliminary tests below performed on an engineering-build Skylake 2-in-1 laptop confirm these findings. In our testing of 4K HEVC video for CPU Performance, Memory Usage and Frames per Second, all were significantly improved when DivX Accelerated was on compared to the same tests with DivX Accelerated turned off.

DivX HEVC Community Encoder

DivX HEVC Team is excited to announce an updated version of our command line encoder for HEVC!

Create Tools with DivX265

Our DivX HEVC encoder is a simple command-line encoder that is designed so that other tools can be built around it.

A recent example of what you can do with the DivX265 (DivX HEVC/H.265) encoder is a GUI posted by david55 on VideoHelp.com. After trying a GUI for x265 he decided to try it out with the DivX encoder for its balance between speed and quality. It’s a simple interface that takes the command-line out of our command-line encoder. Just choose your input and output, adjust your settings and select an encoding mode, all using DivX HEVC encoder.

DivX Live Debut

DivX Live is the newest addition to our end-to-end HEVC solution. An exciting new feature still in beta, DivX Web Player (released in DivX v10.2), will support DivX Live streaming of HEVC video over MPEG-DASH right in your browser on Windows or Mac computers. The sections below will explain the new DivX Live streaming feature in greater detail.

What is DivX Live?

It is DivX’s simultaneous adoption of DASH and HEVC. DivX Live is a new feature built upon the adaptive streaming technology initially launched with DivX Plus Streaming. In technical terms, DivX Live implements the Dynamic Adaptive Streaming over Http (DASH for short) protocol for Live streaming. The following profile specifications are currently supported by DivX Web Player.
