Hi Amanda,

First, why do you write your emails twice? :-/

I want to add support for OMA DRM Content Format (DCF), an encrypted
file format. Here is my solution:

(1) I've registered *.dcf files in shared-mime-info, MIME type is

(2) We developed a DRM-aware GStreamer file source plug-in that can
decrypt the protected content. So GStreamer can play the content and
extract meta data from it. This means the GStreamer extractor can be
re-used to extract metadata.

Just wondering, why not just add "application/vnd.oma.drm.content" to
the list of mimetypes the gstreamer extractor can handle?

We don't usually do that for generic extractors because it depends on their extensions. GStreamer may or may not have the extension installed to deal with this format.

Plus we write our own extractors if generic ones aren't fast enough - so I don't think it is necessarily a bad thing having a specific extractor for this case.
