Original commit message from CVS: Move a step closer to autoplugging. The element selection in the pipeline works. Slight modification to the typefind function handling. removed the stupid mime types in the mpeg decoders. Adjust videosink for the new caps handling. Modified the queue example to show an error in plan creation; Erik can you solve this? This is the type of pipelines autoplugging uses.
