Installation

Follow these steps:

  1. Uninstall any previous version of these filters. (This is important!) Go to add remove programs, remove oggcodecs.
  2. Make sure media player or any directshow applications are closed.
  3. Run the installer.

Then Windows Media Player or any other directshow application (eg. BSPlayer) will be able to play Ogg Vorbis, Ogg Speex, Ogg Theora, Ogg FLAC and native FLAC.

Starting with version 0.72.1838, development will now be split into a stable and unstable branch. That way, those who just want to play their files can get the stable version, and those who want to live dangerously can get the latest new features without having to wait for me to do proper testing. You can find the unstable builds on the download page.

Most users should download the stable version below.

Current Stable Version (0.71.0946) - 24/02/2006

More bugfixes, particularly to theora. See 0.70 release for more details about recent changes. Docs and source package will be updated on the weekend, there's no major changes there from 0.70. This version is fairly stable now it seems.

Changes this version

  • Fixed bug where player would crash if you dragged it from one monitor to another while playing
  • Fixed COM reference double-release bug
  • Fixed race condition which could crash or hang sometimes after a seek.

Known issues

  • Can't play file with names that use extended character sets (ie Japanese) under certain locales of windows (Thanks Liisachan)
  • AVI Video files encoded with non-integral framerates (ie 29.97) may lose sync, due to rounding bug (Thanks RadicalEd)
  • 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.
