FFSoX Player is a Winamp plug-in based on the FFmpeg and SoX libraries. Using FFmpeg almost all multimedia files may be played, including H.264 and VP8.
excellent input plugin sothat we can use the open source ffmpeg librarys
Very good plugin, even if you can't hear the improvement due to various issue like not enough transparent gear this plugin allow you to play almost every format in existence once you add ffmpeg. Sadly version 2 gives me crackle and pop everywhere, so I'm still using v0.6.3, using it with xmplay :(
