H.264标准

Recommendation H.264: Advanced Video Coding is a document co-published by two international standards bodies, the ITU-T (International Telecommunication Union) and the ISO/IEC (International Organisation for Standardisation/International Electrotechnical Commission). It defines a format or syntax for compressed video and a method for decoding this syntax to produce a displayable video sequence. The standard document does not actually specify how to encode digital video – this is left to the manufacturer of a video encoder – but in practice the encoder is likely to mirror the steps of the decoding process.标准中之提供了decoding的过程,encoding需要厂商自己来实现.
