For playback of various media formats, Windows 7 also introduces an H.264 decoder with Baseline, Main, and High-profile support, up to level 5.1, AAC-LC and HE-AAC v1 (SBR) multichannel, HE-AAC v2 (PS) stereo decoders, MPEG-4 Part 2 Simple Profile and Advanced Simple Profile decoders which includes decoding popular codec implementations such as DivX, Xvid and Nero Digital as well as MJPEG and DV MFT decoders for AVI. Windows Media Player 12 uses the built-in Media Foundation codecs to play these formats by default.
