Codecs: Frequently Asked Questions

gomplayerrl8.gifGOM Player | Screenshot |

GOM Player supports most popular codecs (AVI, DAT, MPEG, DivX plus many more) with its own embedded codec system that you won't have to look for appropriate codecs everytime you can't play a certain video format.

You can watch VideoCD, SVCD, DVD, 3ivx, DivX 3/4/5 and even can watch video files while you are downloading them!

What's good: rulesPlayer is a hidden gem among multimedia applications. rulesPlayer cover all existing video files (Real Media, Quicktime, DivX etc..) without any codec pack. Also rulesPlayer offers a basic menu and hotkeys, giving you quick access to the playback functions.

What's bad: I don't know if is really a bad thing: to install rulesPlayer a good internet connection is required not because of his size (1.1mb) but because it automatically download all the necessary codecs.

2011 Notes: RulesPlayer development is pretty dead, though is still a good multimedia player for Windows XP. Doesn't support AERO glass on Windows 7.

RsNKQ.pngSPlayer | Screenshot |

SPlayer is a simple and open-source media player , which supports all the popular media formats, including DVDRip, HDTV, RMVB, QuickTime, MPEG-2, MPEG-4, AC3/DTS, VP3/6/7, Indeo, XVD, OGG / OGM, APE, FLAC, TTA, AAC, MPC, 3GP/AMR, and subtitles. Play Incomplete / Broken files. Support GPU acceleration. Optimization for multi-core SSE2 SSE3 MMX GPU etc.

What's good: SPlayer plays major video and audio formats, as well as Blu-Ray and DVDs. Portable version available. Clean & Simple interface.

What's bad: Small parts of the actual user interface in Chinese.

2011 Notes: SPlayer development is very active nowadays. Lot of features has been added and the portable version is a must have on my USB applications suite.

kmplayerfe1.pngKMPlayer | Screenshot |

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.

What's good: Pleasant & elegant interface; support many, many media file types. Lot of settings, tweaks and options.

What's bad: Nothing. Maybe the installer that contains a ''Pandora Toolbar'' but is optional.

2011 Notes: The KMPlayer developer left the team to build another great media player : PotPlayer (see details below).

V8ZzP.pngVideoLan | Screenshot |

VideoLAN is an excellent multimedia player with it's own plugins for playing different formats, so it doesn't need any codecs to be installed. It works great for previewing partially downloaded files too as well as DVDs, VCDs, and various streaming protocols. It can also be used as a server to stream in unicast or multicast in IPv4 or IPv6 on a high-bandwidth network.

What's good: VLC will play 90% of your media files shoutcast streams included.

What's bad: VLC doesn't support Real Media & Quicktime; some problems with subtitles.

2011 Notes: VideoLan is one of my favorite software this year. Is still under heavy development but since last year so VLC grown up a lot. It has more settings than ever, the installer is clean (without any toolbar) , more file types has been added.

smplayericonyz6.pngSMPlayer | Screenshot |

SMPlayer intends to be a complete front-end for MPlayer, from basic features like playing videos, DVDs, and VCDs to more advanced features like support for MPlayer filters and more.

What's good: Yet another Windows Media Player replacement. Support for hundreds of different media files. Someone doesn't like VideoLan also; you should try SMPlayer, it's what VideoLan should be and more.

What's bad: Nothing.

2011 Notes: None.

282lvyo.pngRadLight | Screenshot |

RadLight is a media player that allows a user to experience a large variety of multimedia, including content such as DivX, DVD video (requires third-party plugin) or AAC/MP4 audio.

What's good: I like this one! The clean and old skool GUI it reminds me of Media Player Classic. The free version used in conjunction with FFDSHOW, it works luvly.

What's bad: Don't download the ''PRO'' version for free because is not really free but is ad supported by AdVantage.

2011 Notes: Outdated but still great. Don't get fooled by classic, OLD STYLE interface. RadLight still has more to offer and works perfectly under Windows 7 even the last version has been created few years ago.

c91Gm.pngBS.Player Free | Screenshot |

BS.Player is a great media player that features anything you need to watch movies or any other kind of video on your PC. BS.Player supports all popular video formats (and audio as well, in case you were wondering) and though its basic interface is not really the nicest one I've seen, you can easily customize it with skins.

What's good: A powerful media player. Lot of options and settings. One of the oldest multimedia software available on the web maybe older than Windows itself (sarcasm).

What's bad: Take care installing the ''FREE'' version. It tries to install a toolbar, change your home page etc.. Ugly interface but BS.Player supports skins. Like other multimedia software a ''PRO'' paid version is available, that is pretty useless. Those guys must understand that we hate toolbars and change their business model.

2011 Notes: None.

fLN2w.pngALLPlayer | Screenshot |

ALLPlayer claims to be the most popular program for watching movies with subtitles. It plays all known media formats, and futhermore has an implemented LiveUpdate function to update the latest codecs if there is a problem with opening a movie file. The program also searches for matching subtitles in all languages automatically. Unlike most players, ALLPlayer is not merely an overlay for MediaPlayer, and it uses DirectX, which makes it possible to play any movie. The program is also integrated with a speech synthesizer application, allowing you to watch movies with subtitles with a reader (dubbing).

What's good: Pleasant interface; support many, many media file types; Lot of settings and options to play with.

What's bad: The ''LiveUpdate function to update the latest codecs'' is available only in the ''Premium'' paid version of ALLPlayer so I don't understand why ALLPlayer is the ''most popular program for watching movies with subtitles''.

2011 Notes: None.

f2Jer.pngALPlayer | Screenshot |

AlPlayer (formerly ALShow) is a video player that includes the basic codecs to play most of the movies. For those rare kinds of codecs that are not popularly used, ALPlayer will download the codec from ALPlayer Codec Center then install it for you. With ALPlayer, you do not have to wander around the internet to find the proper codec for your video. ALPlayer will do everything for you.

What's good: A nice, tiny but in the same time powerful media player. In my tests played everything without any problems.

What's bad: Nothing bad here, if you need a little media player even for old systems like XP or Windows 2000 ALPlayer is a good choice. Not for the geeks that expect a lot of settings to mess up. Don't get confused with the name: ALPlayer is not the same with ALLPlayer.

2011 Notes: None.

S6gF0.pngMedia Player Classic - Home Cinema

Media Player Classic is an extremely light-weight media player for Windows. MPC has, for instance, a built in DVD player with real-time zoom, support for AVI subtitles, QuickTime and RealVideo support (requires QT and/or Real player), and lots more.

What's good: Media Player Classic it's a great Windows Media Player replacement. Support for hundreds of different media files.

What's bad: Emmm, hard to find something bad in MPC. Maybe some speed issues but this depends exclusively by your PC.

2011 Notes: None.

What's bad: Fails to play some Blu-ray discs but the price is right (Freeware).

2011 Notes: None.

Must have filters, codecs, addons:

Koepi's XviD Codec

The original XviD, nothing better has been inventend yet. To be used with Media Player Classic or Windows Media Player.

Jawor's Xvid Codec

Custom XviD builds by Jawor. Small installer size and more settings than the original XviD will make this one a better XviD.

DirectVobSub (Subtitle Display)

DirectVobSub is simply a DirectShow filter which can be used to display subtitle files created by VobSub during playback in Windows Media Player, Media Player Classic, Zoom Player and other players as well.

FFDShow Tryouts

FFDSHOW is a DirectShow decoding filter for decompressing DivX, XviD, WMV, MPEG-1 and MPEG-2 movies.

Local Subtitles for WMP

This is a background plug-in for Windows Media Player. Its sole purpose is enabling textual subtitles, that accompany media files in formats not supported directly by Microsoft.

ReClock DirectShow Filter

The purpose of ReClock is to definitely get rid of jerky playback of video material on a PC (AVI, MKV, DVD, Blu-ray, etc) or a HTPC driving a TV, a flat panel, or a video-projector.

CoreAVC H.264 Video Decoder

Codec Packs are evil, don't install them!! by Chris Lanier Interesting Read

Random Codec Packs Are Evil Topics

Already read the ZCP Guide and need even more help? Are you still undecided ? Here's my recipe:

- for Beginners - MPUI or VideoLan or rulesPlayer or a slim codec pack from above, nothing else.

- for Advanced Users - MPUI or VideoLan or FFDshow+Media Player Classic+DirectVobSub or FFDshow+Windows Media Player+DirectVobSub or a slim codec pack from above+Media Player Classic.

2011 Update:

This year seems to be very hard to find a winner since Windows 7 - infamous Windows Media Player 12 support almost every video format.

Geeks should have a look over KMPlayer, UMPlayer, VideoLan, MPC-HC and Light Alloy.

Pioneers can try PotPlayer, Kantaris Media Player, MPlayer WW, MPUI-HCB and DaPlayer.

Non technical people - Windows Media Player 12 on Windows 7 is enough to play almost everything. Anyway for exotic file formats, I recommend a combo with FFDshow or CCCP.

Still using Windows XP? Grab Light Alloy, MPC-HC, KMPlayer, VideoLan or UMPlayer.

Ok, but which one is the best? This year Light Alloy get my vote together with UMPlayer. Can't do better and I know but both are fine video players and both look and work just like a ''2011'' software should work.

NOTE: Has anyone monitored the installation of K - Lite Codec Pack to see what kind of hit it takes on the registry? I don't think, anyway here's an interesting result : Keys added 1330, Values added 805! That's a lot so think twice before you want to install a ''MEGA CODEC STUFF''. :x

I use CCCP

Added by Fred Derf:

I cannot find evidence of this being 100% legal/freeware or not so I'll leave it for now.

I personally use VLC and absolutely nothing else. But for my gf's laptop, I install the K-Lite Mega Codec pack, just for simplicity's sake. I uncheck absolutely everything she wouldn't need. It's sort of handy just to have everything in one spot. Plus, according to my (personal) benchmarks, I don't really see a difference before and after installing it (when I used to do so on my own PC). And I've NEVER had stability or messed up issues. I guess I just may be lucky.

Yep. I find it very useful aswell with everything one spot. Media Player Classic + Codecs = (Y)

codec "packs" are always a bad idea, its best to stay in control of which codecs you have installed, not just batch install a ton of them.

Interesting read and facts......I never thought about it and didn't pay any atention to it, but this opened my eyes....thanks....

Unfortunately as I read once I installed a codec pack it is almost impossible to redo the changes made to the registry....but next time i reinstall my system I'll follow these advices....

keep up posting things in this manner.... Thanks

Anyone tired of codecs and othe licencing nonsense VLC! -The king of all players

That's part of the reason why people don't like codec packs. :p

Ok, thats why I recomend VLC, but to get rid of them (if u cant see them on windows ad remove(with updates clicked)), get Ace Utilityes 30 day trial- the best utlity known to me for very many purposes. In it u'll find uninstall manager(the one that shows everything) and get it removed!

At the same time (once u got it instaled) run ace utility fully- that will be two rabits instead of one pig(or evil) :laugh:

Posts referring to obvious illegal content have been removed. Not every codec pack contains 100% freeware / open-source software.
