DirectShow FilterPack is a lite-weight package of DirectShow media filters which, together with FFDShow, will enable you to play many different kinds of encoded/encrypted audio and video with your favorite DirectShow media player.
By default Windows is capable of playing MP3 Audio (MP3-files) because of the "MPEG-1 Stream Splitter" and the "Fraunhofer MP3 Decoder" which are shipped with Windows. But unlike MP3, Windows doesn't know how to handle Vorbis Audio (OGG-files).
With the OGG Splitter (part of DSFP) and FFDShow being able to decode Vorbis Audio, Windows can now handle Vorbis Audio (OGG-files).
DirectShow FilterPack consists of 10 Source- and Splitter filters (stage 1 and 2). That's because another piece of software called FFDShow is already capable of decoding a lot of encoded/encrypted audio and video, but FFDShow can do much more than that.
DirectShow FilterPack greatly relies on FFDShow and FFDShow is almost completely useless without Splitter filters, but DirectShow FilterPack and FFDShow together can play/render almost anything! Many Splitter filters and a couple of Source filters are also embedded in Media Player Classic (a DirectShow media player). But Media Player Classic can't play/render lossless audio for instance, so in this case DirectShow FilterPack is still usefull.
* DirectShow based media player like;
* Zoom Player, RadLight, The Core Media Player, Windows Media Player, and Media Player Classic (MPC).
(Note: This doesnt include WinAMP or XMPlay, since those are plug-in based media players.)
(Note: Im not mentioning Media Player Classic (MPC), since MPC has most of these Splitter filters already integrated.)
* QuickTime Alternative (optional)
* QuickTime Alternative allows you to play QuickTime files (MOV,QT) without having to install QuickTime Player.
* Real Alternative (optional)
* Real Alternative allows you to play RealMedia files (RA,RM,RAM,RMVB) without having to install RealPlayer.
