 For avidemux I currently have a big patch doing memory optimized index handling.
 It basically thins out the index to save memory. Right now it only keeps index
 entries marked with the avi keyframe flag.

 This way the different requirements of desktop and embedded platforms could be
 encapsulated in the indexer strategy.
 
+== ranking ==
+Autopluggers like playbin and decodebin use the element caps plus static ranks
+to create piplines.
+The rank of an elemnt right now refers to the quality/maturity of the element.
+Elements with higher rank should be functionaly more complete. If we have
+multiple elements that are feature complete there is a draw.
+
+There are more decission criteria thinkable:
+* ressource usage (CPU, memory)
+* license (proprietary, open source)
+* quality (in terms of the audio/image quality)
+
+One problem of taking criteria like quality and performance into account when
+autoplugging, is that elemnts might have options to control them.
