The LEAD H264 Decoder is a DirectShow® decoder that can decompress video compressed by any H264 codec A COmpressor combined with a DECompressor, or encoder and a decoder, which allows you to both compress and decompress that same data. COmpressor Also known as an encoder, this is a module or algorithm to compress data.

Playing that data back requires a decompressor, or decoder. and a decoder Also known as a decompressor, this is a module or algorithm to decompress data. , which allows you to both compress and decompress that same data.. Note that there are two DirectShow® encoders and only one DirectShow® decoder because the DirectShow® decoder can decode data encoded by any codec. The DirectShow® decoder is preferred over the DirectX Media Object (DMO) decoder when playing H264 video from AVI, Ogg or any non-WMV format in both Media Player and other DirectShow-based players.

The DirectShow® decoder is capable of playing H264 video from WMV files in players built with LEADTOOLS or DirectShow®. Windows Media Player will NOT use a DirectShow® decoder to play WMV files. It will insist on using DMO or VFW decoders to play WMV files. Media Player will, however, use DirectShow® decoders to play AVI or Ogg files.
