[packagekit] GStreamer Structure

[Sebastian Heinlein]

Hello,

recently the provided Gstreamer plugins have been added to the package
meta data in Debian and therefor in Ubuntu too.

When making use of this in the APT backend, I was wondering about all
the structure rewriting which happens.

This is an example request of GStreamer which it gives to the installer
plugin (in this case requesting for a mp3 decoder):

gstreamer|0.10|totem|MPEG-1 Layer 3 (MP3) decoder|decoder-audio/mpeg,
mpegversion=(int)1, layer=(int)3 (MPEG Layer 3 (MP3) decoder

An here is what PackageKit gives to the backend:

gstreamer0.10(decoder-audio/mpeg)(mpgversion=1)(layer=3)

What I need is to get the Gst object type and the structure to convert
it into caps again:

Package.hasGstreamerPlugin("decoder", "audio/mpeg, version=1, layer=3")

How do you deal with this in yum internally?

Could we try to find a format which would avoid all this rewriting?

Cheers,

Sebastian
