Installing this package you will be able to play Ogg Vorbis, Ogg Speex, Ogg Theora and Ogg FLAC with Media Player or any other DirectShow application like The Core Media Player, Foobar2000...

Known issues :

- If you want to install both 32bit and 64 bit installers on a x64 system you will need to change the path of the second run installer. For example if you run 32bit installer first, you need to change for the 64 bit installer the path from "C:\Program Files (x86)\Xiph.Org\Ogg Codecs\" "to C:\Program Files\Xiph.Org\Ogg Codecs\". This is due to a bug in the installer (Ticket #1474)
- Can't play file with names that use extended character sets (ie Japanese) under certain locales of windows (Thanks Liisachan)
- Make the installer properly detect if it's already installed. If you don't uninstall the old version you will get multiple identical file masks in WMP
- If you are getting codec problems, there appears to be a conflict with something in Media Player Classic... it tries to enforce the use of another ogg demultiplexer, either by design or accident.If you see in MPC it complaining about a media subtype with a GUID {CDDCA2D5-6D75-4F98-840E737BEDD5C63B}. This is the guid of the old tobias vorbis filter, and this one {8D2FD10B-5841-4a6b-8905-588FEC1ADED9} is CoreVorbis. This is most likely due to the fact that these filters don't clean up the registry when they uninstall. I am working on something to "clean up" all these remnants from the registry (don't expect it too soon though... it's not that high priority). You can also apparently an option to disable the inbuilt demuxer (Thanks Bond)
- Cannot handle any chained multiplexed files or streams.

This component is not enabled by default in the installer and it is only a technical preview - only basic playback (play/pause by left click button), no seeking, no controls and no HTML5 < video > interfaces support.
