There are a few "named" ranks - minimal, normal, maximum, and so on.
But rank is just a number, so you can have intermediate values too -
which this plugin has. That's actually fine.

This looks wrong in several ways:
 "video/x-mp4-sp" isn't, as far as I know, used anywhere in gstreamer.
Of course, you might be using a custom demuxer that produces it, but
you didn't mention anything like that.

So I assume your decoder isn't actually compatible with any types that
any demuxers might output.

Additionally, framerate in gstreamer is a fraction, you have it here
as an integer.

Make sure you fix up the other things mentioned by other people too.
