* Transcoding from MPEG-2, VC-1 and H.264/AVC elementary streams.
* Baseline, Main and High (with restrictions) Profile support
* I, P and B frames support
* CABAC/CAVLC entropy
* Deblocking filter
* Sub-pel motion estimation
* Intra-blocks in P-frames
* ABR rate control (Average bitrate, HRD is not maintained yet)
* Possible input video formats: YV12, YUV2 MPEG-2, H.264/AVC, VC-1 (H.264/AVC and VC-1 are supported for video cards with 1.1 architecture only – please see hardware requirements below)
* Up to 50% better performance
* 4x4 intra partitioning
* Additional color converter input formats have been added
for OpenCL:
* Baseline profile
* I, P and B frames support
* CABAC/CAVLC entropy
* Deblocking filter
* Intra-blocks in P-frames
* ABR rate control (Average bitrate, HRD is not maintained)
* 4x4 intra partitioning
* Performance is ~30fps for 1080p video on a top ATI hardware
