Description Shlomi Fish 2010-03-18 22:48:56 UTC
Version:           4.3.80 (using KDE 4.4.1)
OS:                Linux
Installed from:    Mandriva RPMs

The Phonon gstreamer backend does not list all available mime types because it only access the 0'th struct of the caps struct. As a result, many file types (including .it , .xm and .s3m files) cannot be dragged and dropped and played in Amarok. Here is a patch that corrects the problem (I will also attach it):

commit 97555adfca6830c23682f03eba72b8b44ec38f28

    gstreamer: Include all supported mime types.
    
    Shlomi Fish discovered that not all mime types supported by the gstreamer
    backend were parsed into Phonon. This change ensures that that all mime types are
    parsed correctly.
    
    Thanks to Shlomi for the patch.

reassigning to the new bugzilla product for better bug tracing of the various backends. Sorry for the noise.
