OGM Portable Player

The flash-based Cowon O2, with its gorgeous touch screen and crystal-clear sound, is sure to please customers looking for a fairly inexpensive PVP.

Video playback on the O2's 4.3-inch screen is smooth and sharp, with the right amount of brightness and color balance. The 480-by-272-pixel screen isn't as impressive as the A3's 800-by-400-pixel display (or the gorgeous 800-by-600-pixel screen found on the Archos 5), but video on the O2 looks great anyway.

The O2's audio quality and support are as impressive as its video output. The unit's audio player supports AC3, Apple Lossless, FLAC, G.726, Monkey Audio, MPEG-1 Layer 1/2/3, MusePack, Ogg FLAC, Ogg Vorbis, PCM, True Audio, WavPack, and WMA. In our PC World Test Center's sound tests, the O2 had a signal-to-noise ratio average (the higher the number, the cleaner the sound) of 85 db--higher than some of the top-ranked players on our chart. The O2 has some great sound-enhancement features too, like a 10-band equalizer and settings for 3D sound quality. In my hands-on tests, audio sounded crisp, with no detectable static or distortion. The included earbuds don't do the sound justice, however, and they were a bit too large to fit comfortably my ears.

The O2 supports an astonishing number of video files and has no file size limits. As a result, if your media collection contains files that use various video formats, you won't be burdened with the task of converting them to a unitary format. The O2 natively supports ASF, AVI, DAT, DivX, h.264, M-JPEG, MKV, MP4, MPEG-1, MPEG-4, MTV, OGM, WMV, WMV 9/8/7, and XviD.

If you want to get video file from Cowon O2 to play online, OGM to FLV tool will do all you want with fast speed.

About OGM and OGG

Is it just the name difference?
I wish it were that simple. The biggest problem is that people are using OGM primarily to encode DVD's with DivX video and Vorbis audio. I fear that people might be using OGM, and convince themselves that they're using completely free software, when they're not. After all, 'Ogg' is from Xiph, and Xiph only produces free stuff. DivX and XviD are MPEG-4 variants, and subject to any holds that the MPEG patents have on those technologies.

Again, nothing wrong with DivX or XviD, they're just not completely open standards. Patents apply. It doesn't mean they're not useful, it just means that you might be getting more than you bargained for on the legal side of things.

More about technical differences between Ogg and OGM (Ogg vs OGM)

Ogg and Ogm file format are the same. The main difference is the first header in each stream. OGM uses several standardised header formats, audio, video and text, in order to make identifying unknown codecs easier in directshow (and subsequently other frameworks). That is with those three headers you can use any audio or video format you choose without have to write custom header parsing routines for each codec in the demuxer.

In other words ogmtools provides the standard du jeur for encapsulating various common-in-avi codecs in an Ogg bitstream, like 'divx', 'mp3' and so on.

There are quick tools to convert OGM to Flash. You may get the best video quality to share online with fast speed.

It's capabilities have now been expanded to include the conversion of .mkv and .ogm videos into .mp4 files with presets for iPod/iPhone. Presets for Apple TV, Playstation 3 and Xbox 360 are also included but due to my limited ability to test on these platforms, they should probably be considered beta.

How to play and convert OGM to Flash?

Do you have any chance to download a movie and got it with .ogm extension. Do not take it as virus even though your Windows system doesn't recognize the file.

The OGM extension is typically associated with video files. OGM is the Ogg Vorbis video container format, similar to AVI or MP4, which generally contains Ogg Vorbis audio and a video stream that is often DivX, XviD or Theora video format. To play an OGM file, you have one of two easy options.

The cross-platform solution for playing back OGM files on Windows, Mac OS X and Linux is VLC Media Player. VLC supports playback of OGM, MP4, MOV, most MPEG files and most other audio and video formats. The most glaring omission from the list of supported formats is RealMedia files. After installing VLC Player, the OGM video file should automatically playback using VLC.

If you prefer to playback OGM files using Windows Media Player, you need to download a codec pack to add support for OGM to Windows. The best codec pack for OGG and OGM support in Windows Media Player is the RadLight Ogg Media DirectShow Filters After installing the RadLight filters. You still need to associate the OGM file type with Windows Media Player. To make the proper association, open Windows Explorer and choose Tools > Folder Options from the menu. Click the File Types tab and locate OGM in the list (if it doesn't show up, click new and add it). Click the Change button and Select Program from a list to choose Windows Media Player. Select Windows Media Player from the list and click OK. Close the Folder Options and any OGM file on your system should now automatically open in Windows Media Player.

For the conversion from OGM to Flash on Windows, here is a quick solution. Just download and install Flash Video MX Pro, and it can convert OGM to Flash for video sharing on website. If you get error message about importing the OGM video, just try to play it on Windows Media Player and it shall work then.
