just so we are clear on terms;
 - m-p-i = media-player-info
 - ID_MEDIA_PLAYER be the device id added by udev (via m-p-i).
 - m-p-i store files in /usr/share/media-player-info/ID_MEDIA_PLAYER

I don't necessarily think there needs to be a mapping. The developer could
parse the media-player-info file for the device, it will contain a section like

[Encoding]
GstEncodingProfile=foo;bar;baz

The developer can the go an look at the profile file in
/usr/share/gstreamer-encoding-profiles/{foo,bar,baz)

Of course this requires that those m-p-i files that want to encode all be
modified. Another alternative might be putting some default files for common
devices in /usr/share/gstreamer-encoding/profiles/$ID_MEDIA_PLAYER but I don't
think that is any cleaner, since at least in the case of ipod, the single m-p-i
file (hence single ID_MEDIA_PLAYER key) describes multiple devices that also
support many encoding
