This is actually how flash does things. Embedded video frames (inside a SWF) is
contained in a videoframe where the used codec is identified using a number
(see http://sswf.sourceforge.net/SWFalexref.html#tag_definevideostream), and it
is this number i'm talking about (Klaus too i guess) when talking about
codecIDs. FLV consists of frames using the same IDs (http://osflash.org/flv),
including audio where specific IDs also means specific codecs. This is why i
think we have to choose some IDs to match codecs. We could perhaps probe for
different video types using other methods...

Support for new codecs probably wont be (officially) supported in the upcoming
release.
