X264 Development Notes
Contents[hide] |
Getting Started
Books
- H.264 and Mpeg-4 Video Compression: Video Coding for Next Generation Multimedia, Iain E. G. Richardson
Advice
Suggestions
- Be willing to learn
- Experiment
- Ask Questions (irc.freenode.net/#x264dev)
- Sample clips: http://media.xiph.org/video/derf
- check out elecard streameye
Potential Projects
- Performance improvements (asm optimization, etc), particularly wanted: NEON stuff.
- Algorithmic improvements. Examples of past projects: viterbi, b-adapt, macroblock-tree, ratecontrol, psy-rd
- support for new features in the h.264 spec, such as: MBAFF, 4:2:2/4:4:4, weightp, 10-bit
- Support for new enconder features independent of the spec, such as: sliced threads, low-latency output, threadpools, etc
- new external-to-the-main-encoder features (x264 features), such as audio support, new output muxers, new input modules, filters, etc
