H.264 is a relatively new video encoding standard that aims to provide high quality video at low bitrates. It is also known as MPEG-4 Part 10 or Advanced Video Coding (AVC). It improves upon the MPEG-4 Part 2 Advanced Simple Profile (ASP) standard that is used by XviD and DivX. The standard includes four profiles listed from most basic to best: Baseline, Extended, Main, and High.

It was published as an official ISO standard in May 2005.

With a good encoder, such as Nero Digital or x264, the results using this codec at a given bitrate can be better than all other current video compression codecs. Unfortunately, decoding it can take a heavy toll on the CPU.

Both competing next-generation media formats have adopted H.264 High Profile as one of the three codecs to be used to encode the high-definition video that will be stored on their discs, one or both of which will replace DVDs. This is an example of the widespread acceptance of this new codec as a high quality and very efficient encoding standard.

Decoders

Nero Digital includes a DirectShow decoder for H.264, and so does ffdshow. Interestingly, with a sufficiently new driver, many cards in the 6xxx+ GeForce series are said to be able to accelerate H.264 decoding in hardware. In addition to the the Gowell HD2-G8xx series, there are plans of releasing more standalone DVD players that can play H.264. Currently, all standalones that play high-definition video from next-generation media support it since they need to decode at least H.264 High Profile, due to the reason stated above.
