Video Coding Engine

Video Code Engine (VCE, was earlier referred to as Video Coding Engine,[1] Video Compression Engine[2] or Video Codec Engine[3] in official AMD documentation) is AMD's video encoding application-specific integrated circuit implementing the video codec H.264/MPEG-4 AVC. Since 2012 it was integrated into all of their GPUs and APUs except Oland.

VCE was introduced with the Radeon HD 7000 Series on 22 December 2011.[4][5][6] VCE occupies a considerable amount of the die surface at the time of its introduction[7] and is not to be confused with AMD's Unified Video Decoder (UVD).

As of AMD Raven Ridge (released January 2018), UVD and VCE were succeeded by Video Core Next (VCN).

Overview
In "full-fixed mode" the entire computation is done by the fixed-function VCE unit. Full-fixed mode can be accessed through the OpenMAX IL API.
The entropy encoding block of the VCE ASIC is also separately accessible, enabling "hybrid mode". In "hybrid mode" most of the computation is done by the 3D engine of the GPU. Using AMD's Accelerated Parallel Programming SDK and OpenCL developers can create hybrid encoders that pair custom motion estimation, inverse discrete cosine transform and motion compensation with the hardware entropy encoding to achieve faster than real-time encoding.

The handling of video data involves computation of data compression algorithms and possibly of video processing algorithms. As the template compression methods shows, lossy video compression algorithms involve the steps: motion estimation (ME), discrete cosine transform (DCT), and entropy encoding (EC).

AMD Video Code Engine (VCE) is a full hardware implementation of the video codec H.264/MPEG-4 AVC. It is capable of delivering 1080p at 60 frames/sec. Because its entropy encoding block is also a separately accessible Video Codec Engine, it can be operated in two modes: full-fixed mode and hybrid mode.[8][9]

By employing AMD APP SDK, available for Linux and Microsoft Windows, developers can create hybrid encoders that pair custom motion estimation, inverse discrete cosine transform and motion compensation with the hardware entropy encoding to achieve faster than real-time encoding. In hybrid mode, only the entropy encoding block of the VCE unit is used, while the remaining computation is offloaded to the 3D engine of the GPU, so the computing scales with the number of available compute units (CUs).

VCE 1.0

As of April 2014, there are two versions of VCE.[1] Version 1.0 supports H.264 YUV420 (I & P frames), H.264 SVC Temporal Encode VCE, and Display Encode Mode (DEM).

It can be found on:

  • Piledriver-based

  1. The Radeon 100 Series has programmable pixel shaders, but do not fully comply with DirectX 8 or Pixel Shader 1.0. See article on R100's pixel shaders.
  2. R300, R400 and R500 based cards do not fully comply with OpenGL 2+ as the hardware does not support all types of non-power of two (NPOT) textures.
  3. OpenGL 4+ compliance requires supporting FP64 shaders and these are emulated on some TeraScale chips using 32-bit hardware.
  4. The UVD and VCE were replaced by the Video Core Next (VCN) ASIC in the Raven Ridge APU implementation of Vega.
  5. Video processing for video frame rate interpolation technique. In Windows it works as a DirectShow filter in your player. In Linux, there is no support on the part of drivers and / or community.
  6. To play protected video content, it also requires card, operating system, driver, and application support. A compatible HDCP display is also needed for this. HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup.
  7. More displays may be supported with native DisplayPort connections, or splitting the maximum resolution between multiple monitors with active converters.
  8. DRM (Direct Rendering Manager) is a component of the Linux kernel. AMDgpu is the Linux kernel module. Support in this table refers to the most current version.

Operating system support

The VCE SIP core needs to be supported by the device driver. The device driver provides one or multiple interfaces, e. g. OpenMAX IL. One of these interfaces is then used by end-user software, like GStreamer or HandBrake (HandBrake rejected VCE support in December 2016,[43] but added it in December 2018[44]), to access the VCE hardware and make use of it.

AMD's proprietary device driver AMD Catalyst is available for multiple operating systems and support for VCE was added to it. Additionally, a free device driver is available. This driver also supports the VCE hardware.

Linux
Support for the VCE ASIC is contained in the Linux kernel device driver amdgpu.
Main articles: AMD Catalyst for Linux and Free Radeon driver

Windows

The software "MediaShow Espresso Video Transcoding" seems to utilize VCE and UVD to the fullest extent possible.[49]

XSplit Broadcaster supports VCE from version 1.3.[50]

Open Broadcaster Software (OBS Studio) supports VCE for recording and streaming. The original Open Broadcaster Software (OBS) requires a fork build in order to enable VCE.[51]

AMD Radeon Software supports VCE with built in game capture ("Radeon ReLive") and use AMD AMF/VCE on APU or Radeon Graphics card to reduce FPS drop when capturing game or video content.[52]

HandBrake added Video Coding Engine support in version 1.2.0 in December 2018.[44]

Successor
Main article: Video Core Next

The VCE was succeeded by AMD Video Core Next in the Raven Ridge series of APUs released in October 2017. The VCN combines both encode (VCE) and decode (UVD).[53]
