This is not my typical blog post, but if it helps achieve the goal, so be it.
Zen Kavanaugh, who used to develop the Ogg DirectShow filters is not able to continue maintaining these. Therefore, the DirectShow filters are now searching for a new maintainer.
If you develop in Windows and are able to compile, test and package the DirectShow filters that are available from http://www.illiminable.com/ogg/, please consider becoming the maintainer.
At this point in time, there is not much actual development required – just the occasional application of a patch, compilation, packaging and then publication.
This is really important, so if you can help you should really consider stepping forward.
