x265 is a free software library and application for encoding video streams into the H.265/MPEG-H HEVC compression format, and is released under the terms of the GNU GPL. Provides next-generation compression and codec; fast and excellent quality; the APIs are similar to x264 APIs.
Encoder features
- Full prediction and transform quad-tree recursion supported
- Adaptive B-frame placement
- B-frames as references / arbitrary frame order
- CABAC entropy coding
- Intra: all block types (32×32, 16×16, 8×8, 4×4, and PCM with all predictions)
- Inter P: all partitions (from 64×64 down to 8×4)
- Inter B: partitions from 64×64 down to 8×4 (including all merge modes and biprediction)
- Weighted prediction for P slices
- Multiple reference frames
- Ratecontrol: constant quantizer, constant quality, single pass ABR, optional VBV
- Scenecut detection
- Parallel encoding on multiple CPUs, both frame-level and wavefront parallelism
