How to play OGM files

An OGM file is anOGG media file. OGM is acontainer format that can store video streams, audio streams and subtitles. This article shows how to play OGM files and use some of its advantages over theAVI container. It details the easiest method as well as showing to get OGM files working on general players likeWindows Media Player.

What is OGM? What do I need to play it?

OGM is a container format that can store video, audio and subtitle streams, but also supports multiple subtitle tracks, multiple audio of differing formats, support for chapters andVorbis audio. To play these files you need three things;Haali Media Splitter (orOggDS or similar), decoders for the video and audio streams included and a software player. But before we get into installing all of that, I just want to mention theVLC player and how it can make this much easier.

The Easiest Method

Download and install theVLC player. The VLC package already includes software to play OGM files as well as the video and audio content (usually) and can use some of its extra features.

You can getVLC for Windows from this URL.

ClickFile and click theOpen File option.

Now, click theBrowse button next to the first white line at the top of the window with title "Open.." and navigate through your hard drive for the video you wish to watch and select it. After you have selected the video, clickOK and VLC will start playing the video you chose.

Using subtitles and multiple audio with VLC

When playing an OGM file in VLC, right click on the video and see if you can skip between chapters (next,previous etc). You will also see that you can easily change the subtitles while the file keeps playing, or the audio track or any number of things. VLC's support for OGM makes it possibly the best solution for a new user.

Recommended Solution

This is a bit more of a manual method but is beneficial to know about and will add support for OGM files to Windows Media Player and other software. Firstly, you need to install theHaali Media Splitter, this is additional software that will automatically run when Windows Media Player or likewise encounters an OGM file.

Install Haali Media Splitter

Step 1.Download Haali Media Splitter by clicking here.

Step 2. Run theHaali Media Splitter installer. The first thing you will need to do is accept the license agreement of the software. ClickI Agree, and you will be asked to select adestination folder. The default is fine so clickNext and you will be asked to specify aStart Menu folder, again, the default is fine so clickNext. Now you have come to theoptions (as the picture shows).

Make sure that theEnable OGG/OGM support option is selected and clickInstall. It should only take a few seconds before it is complete. Now, Windows Media Player has the ability to open OGM files, now we need to provide support for the video and audio information in the files to ensure playback.

Install and configure FFDShow

Step 1. The obvious and vital first step is todownload FFDShow by clicking here.

Step 2. Now you have to install FFDShow on your Windows operating system (the OS used in this example is XP Pro). Run the installer. Select yourlanguage and clickNext. Now you must accept thelicense agreement of FFDShow; select"I accept the agreement" and clickNext. Now you can choose aninstall directory (default is fine) and clickNext again. You are now on theSelect Components screen;"VfW Interface" should be selected by default, but if it is not, then please select it as shown.

ClickNext and select astart menu folder (default is perfectly fine again), Click Next again and now you reach the"Select Additional Tasks" screen.

It is important now that you ensure that under"Decode the following video formats with ffdshow",H.264 / AVC,DivX, andXviD options are selected. Scroll down further until you reach"Decode the following audio formats with ffdshow" and just ensure thatMP3,AC3 andVorbis are selected. When you clickNext, you will come to a"Management of compatibility issues" screen.

It is recommended to leave the option to use FFDShow for video only with the programs listed beneath to prevent any compatibility problems with other software.Media Player Classic andWindows Media Player will be in here. ClickNext and you will get the same screen again, this time for audio. ClickNext and select your speaker setup (if you only have 2 speakers, itsstereo). ClickNext again and then"Install".

When the installation is finished, your playback software will now be able to decode video and audio stored within OGM files. Try playing them now inWindows Media Player.To play withWindows Media Player, right click the OGM file and go to"Open With" and then the"Choose Program" option. From the list, select Windows Media Player.

If you get a message alerting you that the extension is not recognized by Windows Media Player, select"Don't ask me again" and click Yes.

Subtitles and multiple audio with Windows Media Player

Look at thesystray on your desktop (the area usually in the lower right hand corner that has the small icons) while the video is playing and looking for theHaali Media Splitter icon hover the mouse over each icon until you find it). Now, Simply right-clicking the icon will bring up a menu allowing you to change the Subtitles ("S") and audio ("A"). See the picture for an example.

If you want to associate OGM files withWindows Media Player (will automatically launch the player when you open the file), you can do so by going to yourControl Panel -->Folder Options. Click theFile Types tab and let the list load. Scroll down to OGM, select it and you will see you have the ability to change what program it is associated with. Change it to WMP or whatever you want and clickApply.

Another option

After you have installed theHaali Media Splitter you can hunt down individual decoders and install them if you want. Some users promote the use of codec packs. Codec packs are big collections of video codecs. At first sight they can appear very useful, as they will install enough codecs to decode just about any video files you can get online. However, they have also been known to cause problems with playback too.

Still though, if you prefer to install a codec pack instead of usingFFDShow, then here are some of your options.

K-Lite Codec Pack [full]
XP Codec Pack
Cole2k Media Codec Pack Advanced
X Codec Pack

Additionally, if you prefer to use a solution where you use a separate video player software and a separate set of codecs, you might want to try out different video players as well. We have agood selection of freeware players available on our site, but here are some of our favorite ones:

Media Player Classic
Zoom Player

It should be noted that sometimes, despite all the efforts, analysis and trial&error you've applied in order to get a video to play, it just wont. Quite often in those cases, even when none of the file analytics programs(such as AVIcodec or VideoInspector) seem to help, you can come to a conclusion that the file is corrupted. If that is the case, you're pretty much out of luck and might want to try to re-download the file in order to see whether the problem was with the download process itself.
