A good audio/video decoding package

Xpcodec, which comes with the Media Player classic player, is an improved version of the old Windows Media Player. The interface is simple and easy to use. In addition to the common AVI and AC3 decoder, The RealPlayer format is also supported. You do not need to install a coorse RealONE to play rmvb. This is also my favorite place. However, I found it missing an Xvid, so I had to install it again. However, the video format is varied, and it is inevitable that this is missing. xpcodec is indeed a good all in one decoding package.
