Well, each combination is a new format. Right? That you have multi media
frameworks that can make combinations easily is great, but for me each
combination is still a separate format.
Now if I'd have a GStreamer (or whatever media framework) library call
gboolean g_streamer_do_you_support (const gchar *that_string)
Then that would be great.
Regretfully right now it's basically a: try, if not, we didn't support
it, sorry. That's of course more expensive than above query.
What I'm most concerned about is knowing what I can give it, and what I
can't give it. In a fast way, preferably. And an equally fast way to,
given a GFile (or a URI), know that string that I can use to query.
Over HTTP, SMTP and IMAP I guess only Content-Type is standardized for
this. Which is why I naturally think about that string for making it
useful for this purpose.
