Overview
x264 Video Codec is a free software library and application for encoding video streams into the H.264/MPEG-4 AVC compression format and is released under the terms of the GNU GPL.
Provides best-in-class performance, compression, and features. Achieves dramatic performance, encoding 4 or more 1080p streams in realtime on a single consumer-level computer. Gives the best quality, having the most advanced psychovisual optimizations. Support features necessary for many different applications, such as television broadcast, Blu-ray low-latency video applications, and web video. x264 Video Codec forms the core of many web video services, such as Youtube, Facebook, Vimeo, and Hulu. It is widely used by television broadcasters and ISPs.

Features and Highlights
- 8x8 and 4x4 adaptive spatial transform
- Adaptive B-frame placement
- B-frames as references / arbitrary frame order
- CAVLC/CABAC entropy coding
- Custom quantization matrices
- Intra: all macroblock types (16x16, 8x8, 4x4, and PCM with all predictions)
- Inter P: all partitions (from 16x16 down to 4x4)
- Inter B: partitions from 16x16 down to 8x8 (including skip/direct)
- Interlacing (MBAFF)
- Multiple reference frames
- Rate control: constant quantizer, constant quality, single or multipass ABR, optional VBV
- Scene cut detection
- A spatial and temporal direct mode in B-frames, adaptive mode selection
