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. 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. 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 ** Trinity APUs (Ax-5xxx, e.g. A10-5800K) ** Richland APUs (Ax-6xxx, e.g. A10-6800K) * GPUs of the Southern Islands generation (GCN1: CAYMAN, ARUBA (Trinity/Richland), CAPE VERDE, PITCAIRN, TAHITI). These are ** Radeon HD 7700 series (except HD 7790 with VCE 2.0) ** Radeon HD 7800 series ** Radeon HD 7900 series ** Radeon HD 8570 to 8990 (except HD 8770 with VCE 2.0) ** Radeon R7 250E, 250X, 265 / R9 270, 270X, 280, 280X ** Radeon R7 360, 370, 455 / R9 370, 370X ** Mobile Radeon HD 77x0M to HD 7970M ** Mobile Radeon HD 8000-Series ** Mobile Radeon Rx M2xx Series (except R9 M280X with VCE 2.0 and R9 M295X with VCE 3.0) ** Mobile Radeon R5 M330 to R9 M390 ** FirePro cards with 1st Generation GCN (GCN1) (Except W2100, which is Oland XT)

VCE 2.0

Compared to the first version, VCE 2.0 adds H.264 YUV444 (I-Frames), B-frames for H.264 YUV420, and improvements to the DEM (Display Encode Mode), which results in a better encoding quality. It can be found on: * Steamroller-based ** Kaveri APUs (Ax-7xxx, e.g. A10-7850K) ** Godavari APUs (Ax-7xxx, e.g. A10-7890K) *
