Bug#339598: wavpack support

[Sebastian Dröge]

Package: gst-plugins0.8
Version: 0.8.11-2
Severity: wishlist

Hi,
please consider adding wavpack support, now that wavpack is in Debian.
Currently the wavpack has a bug on powerpc for which I'll get a fix up
asap, maybe already this evening.

The wavpack plugin also needs one patch to fix
http://bugzilla.gnome.org/show_bug.cgi?id=317774

I've attached the patch, it's from gst cvs

Thanks and bye
