KMPlayer 4.0 ships with minor improvements

Media players, there are so many out there for Windows that it is nearly impossible to compare them all to find out which is best. To name a few popular ones, there is VLC Media Player, SMPlayer, PotPlayer, KMPlayer, UMPlayer, Real Player, Windows Media Player, Media Player Classic Home Cinema and hundreds more.

KMPlayer is a long-standing media player for Windows that is usually listed as one of the top 100 downloads on download websites. According to the player's own website, it is used by more than 300 million users worldwide.

It is popular even though it has been criticized in the past for including adware in its installer and using components that leak information to a server operated by the program's parent company.

Most issues can be avoided by using the portable version of the player. Please note that KMPlayer 4.0 portable is not available at this point in time.

As far as changes go, there are not many which is quite disappointing for a major version bump. The developers have improved the loading speed of the player, updated the main splitter, and integrated Intel RealSense support.

The feature list of the player leaves little room for improvement. It plays nearly any video and audio file out of the box (it ships with binary codecs that it uses so that you don't have to install codecs on the system to add support for those), supports 3D and 4k playback, subtitles and all that good stuff that you would expect a media player to support these days.

In addition, it ships with a boatload of settings that let you tweak the player interface and functionality. For instance, you may select decoders for playback, change priorities, keyboard shortcuts or various video filters and playback controls.

KMPlayer supports local media files and broadcasts, can play optical discs (e.g. video DVDs), supports auto-resume of videos, bookmarking, video capturing and a lot more.

The player displays advertisement on start if you run it without loading a media file right away that advertise Pandora TV and KMPlayer products (Pandora TV is the parent company). These ads are not displayed if you load media files right away.

Playback works really well out of the box but shines when you take the time to configure it extensively to match your needs. There is little incentive on the other hand to switch to KMPlayer if you are making use of a media player such as VLC already as differences are marginal (not taking into account the ads situation at all).

Now You: Which media player are you using right now and why?

    Why not make use of the mplayer.conf?

    Huh, I have never even seen this “font cache” pane; videos play at once for me, using VLC & XP SP3.

      Mike, in theory this should have only been displayed once to you, at the very first video that you played with VLC. The time this window is displayed depends largely on the number of fonts in your font directory.

        huh, I lucked out for a change?? Amazing!!
        Apparently VLC keeps this info through version updates, but I didn’t see this message after a fresh OS install about 8 weeks ago, & a new VLC.

      Great tip, thanks a lot Kishore.

    @Kishore, I’ll try your tips, but does this mean it will no longer show subtitles either?
    I do use subtitles, but the fontcache dialog box pops up (almost) everytime I play a file.

    Could this be related to the fonts I have installed? Or if I add/remove fonts to my system?

    I’ll try to do a fresh install also, if your tips does no work. I’ll post back here later…

    Try running LC with administrator privileges. That seemed to fix it for me

    I am using SMplayer 0.8.6 (64-bit) (Portable Edition) on Windows 7 x64. Even with the -nofontconfig parameter in place SMplayer still scans the fonts. Also, I have enabled normal subtitles and it is still scanning fonts before playing a video. Also, it does this every time the player opens a video after a system restart (only the fist video played).

    Does that mean that only instrumental versions of songs will be available for non-paying users?
