Description
There are codecs that are better than others, and some are plain unusable and irrelevant (such as Dirac, bug #T2979).
<thiblahute>
we should start by sorting the elements by rank in the UI!
<nekohayo>
what? we have such a thing as rank?
<thiblahute>
Yes we do, all the autoplugin system is based on that for selecting elements while building pipelines
<nekohayo>
all these years and nobody told me?!
<thiblahute>
Looks like it...
We should use that system to sort the codecs in order of quality, and perhaps exclude those that don't have a high-enough rank.
