== Potential Projects  ==

*Performance improvements&nbsp;(asm optimization, etc), particularly wanted: NEON stuff. 
*Algorithmic improvements.&nbsp;Examples of past projects: viterbi, b-adapt, macroblock-tree, ratecontrol, psy-rd 
*support for new features in the [http://www.itu.int/rec/dologin_pub.asp?lang=e&id=T-REC-H.264-200305-S!!PDF-E&type=items 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&nbsp;(x264 features), such as audio support, new output muxers, new input modules, filters, etc
