The KMPlayer is a versatile media player which can cover various types of container format such as VCD, DVD, AVI, MKV, Ogg Theora, OGM, 3GP, MPEG-1/2/4, WMV, RealMedia, and QuickTime among others. It handles a wide range of subtitles and allows you to capture audio, video, and screenshots in many ways. The player provides both internal and external filters with a fully controlled environment in terms of connections to other splitters, decoders, audio/video transform filters and renderers without grappling with the DirectShow merit system. Internal filters are not registered to user"s system to keep it from being messed up with system filters. The KMPlayer includes almost all the essential decoders required for media playback. Furthermore, to get beyond the limitation of internal decoders, the external ones such as commercial h.264 decoders or cyberlink/intervideo audio decoders can be specified, so that KMP works optimally by the users" own customization. Even though the KMP is based upon directshow structure, it supports Winamp, Realmedia and Quicktime by the internal logic. Thus, it is possible to specify where to try to connect firstly the media in preferences. In short, the player provides a strong hybrid structure efficient for interconnecting various directshow filters, Winamp input&dsp plugin, and internal filters. The most outstanding feature is that the player has the full control of filter connections to prevent a media playback from being messed. The player can setmultifarious audio and video effects, slow down or increase playbackspeed with regular tone, select parts of a video as favorites, do anexceptionally powerful A-B repeat, remap the keys of remote interfacefor HTPC including overlay screen controls, change a skin dynamicallydepending on a media type playing, and many more. It is completelycustomizable thanks to a wide selection of skins and color schemes, andthe configuration options are extremely extensive.
