x264 Video Codec rev. 2453

Updated: 20 Jul 2014

x264 is a free library for encoding H.264/MPEG-4 AVC video streams.
Important Notes:

To decode, we suggest you to install a recent build of FFDShow, DivX H.264 Decoder or LAV Filters.

A media player that supports H.264 internally is also a good solution if you don't want to mess with codecs, filters, etc:
- MPlayer, there are few interesting frontends for Windows: MPlayer GUI, MPlayer Frontend
- or VLC Media Player, KMPlayer, etc.

VFW and installer were removed! So, you can try the x264Gui, x264 VfW, TX264, Leiming's x264 GUI or the famous MeGUI.

Main Features of x264 Video Codec:

- 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 forms the core of many web video services, such as Youtube, Facebook, Vimeo, and Hulu. It is widely used in television broadcast and by ISP.

Encoder features:

- 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
- Ratecontrol: constant quantizer, constant quality, single or multipass ABR, optional VBV
- Scenecut detection
- Spatial and temporal direct mode in B-frames, adaptive mode selection
- Parallel encoding on multiple CPUs
- Predictive lossless mode
- Psy optimizations for detail retention (adaptive quantization, psy-RD, psy-trellis)
- Zones for arbitrarily adjusting bitrate distribution

Haali Matroska Splitter: is a new DirectShow splitter, based on Haali's C library for .mkv (Matroska), .mp4, .ogg/.ogm and .avi handling.

x264 VfW: is a reworked x264 VfW which contains an integrated VfW decoder. Install it and you'll be able to play and edit all VfW AVC files with no extra software!

h264 fails for old hardware and low performance energy saving machines. Long Live XviD.

x264 is the new hotness of encoders. Compared to XviD and DivX, there really is no comparison.
