Being able to encode specially contrived data in a particular manner can 
be very useful for writing a decoder.

The punchline is that an encoder, a very basic and inefficient one, can 
be trivial compared to a full-featured decoder. Monitor the specs I am 
writing:

   http://wiki.multimedia.cx/index.php?title=Understanding_VC-1
   http://wiki.multimedia.cx/index.php?title=Understanding_AAC

and look for ways to encode very basic bitstreams. Then, test them 
against the official decoder.

When I first wrote an SVQ1 encoder, I simply interated over 16x16 blocks 
and encoded the average for each. Apple's QuickTime Player actually 
played the encoded video, which was very blocky. But the syntax was correct.
