K-Multimedia Player (commonly known as The KMPlayer, KMPlayer or KMP[4][5]) is a media player software for Microsoft Windows which can play a large number of formats including VCD, DVD, AVI, MKV, Ogg, OGM, 3GP, MPEG-1/2/4, WMV, RealMedia, FLV and QuickTime. It has a significant user base and has received strong ratings and reviews on major independent download sites.[6][7][8]

Features

The player handles a wide range of audio, video and subtitles formats and allows one to capture audio, video, and screenshots. It 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 (a system of selecting and prioritizing codecs across the entire Windows operating system[9]). Internal filters are not registered into the system's registry to prevent the operating system from confusing system filters with K-Multimedia Player's filters

The player can set many audio and video effects, slow down or increase playback speed, select parts of a video as favorites, do various A-B repeats, remap the keys of remote interface for HTPC including overlay screen controls, and change a skin dynamically depending on a media type playing. KMP is completely customizable thanks to a wide selection of skins and color schemes, as well extensive the configuration options.[10]

History

K-Multimedia Player was originally developed by Kang Young-Huee and was first released on 1 October 2002.[1] On 5 March 2008, The KMPlayer's Forum announced that the KMPlayer had been acquired by Pandora TV (a Korean streaming video company) in August 2007.[11]

Naming

K-Multimedia Player is known under several names. In version 3.0.0.1438,[8] the player is labeled both KMPlayer and KMP on its main user interface. The About page refers to it as "The KMPlayer Professional Media Player" and "The KMPlayer". The version page refers to it as "KMPlayer". The license page says:

Introduction of KMP K-MultimediaPlayer (Hereinafter, referred to as KMP) : KMP is a freeware. Its full name is K-Multimedia Player. But, it is also called as KMP, KMPlayer, KMP Player or kmp player.

The player is distributed on international download sites under the names "The KMPlayer"[6] and "KMPlayer".[7][8] Its official forums refer to it as "The KMPlayer",[12] while its PandoraTV site calls it "KMPlayer".[13]

Alleged license violations

Gabest, original author of Media Player Classic claimed that KMP was violating the GNU General Public License (GPL) by using GPLed code written by both him and others in a closed-source program.[14] The development team has denied this allegation; they maintain that player did not actually include the mentioned GPL code in the executable, and thus was not breaking any GPL rules.[15] The player was bundled with a GPL component, although when the authors were notified they deleted the GPL breaching part bundled with the program.[16] FFmpeg developers claim that K-Multimedia Player is violating their (and MPlayer's) copyright by distributing binary code from the FFmpeg (and MPlayer) project without offering source code.[17][18] In the K-Multimedia Player forum, it was repeatedly stated that no source code has to be offered to comply with the GPL, therefore denying the allegations.[19] Regarding distribution of GPL binaries, the FSF states that "The general rule is, if you distribute binaries, you must distribute the complete corresponding source code too. The exception for the case where you received a written offer for source code is quite limited." [20]

Reception

KMPlayer has been listed as one of the five best multimedia players by Lifehacker.[21] KMPlayer 2.9 was reviewed by Softpedia editors and has received an overall score of 4 out of 5 earning a rating of "Very Good" and also receiving the Softpedia Pick award.[22] Seth Rosenblatt of CNET's Download.com also reviewed KMPlayer 3.0 and gave it a score of 5 out of 5 saying it "is one of the most powerful freeware video players we've seen" but mentioned a lack of online help or documentation as a shortcoming.[23] The Softonic review by James Thornton called it a “Excellent free multi-format media player”[24]
