Subject: Re: pkg/29653: another bug (with patch, this one)
Date: Fri, 11 Mar 2005 17:13:56 +0100

 Hi,
 
 There is a bug in gst-plugins-0.8.7 which prevents tunesbrowser to play
 aac files. Ths bug is fixed in gst-plugins-0.8.8, but since pkgsrc is
 frozen now, i've made a patch (extracted from gst-plugins cvs) for
 allowing reading qt files in a pipe.

 putting this as patch-ac, then make makepatchsum, and rebuild
 gst-plugins , and tunesbrowser is happy.
