First, get the j2k standard (or draft) if you havnt already.
Second get http://www.crc.ricoh.com/~gormish/jpeg2000conformance/j2kp4files_v1_5.zip
The decoder should decode all the simple files from this (it currently decodes only
2 files)
see http://lists.mplayerhq.hu/pipermail/ffmpeg-soc/2007-August/001511.html

I would suggest that you only work on the decoder for now and leave the
encoder for someone else or later.

Also get jasper so you know how the images should look when decoded correctly

After you got all simple files decoding properly you should submitt a patch to
ffmpeg-dev which will then likely need a few review + patch resend iterations.

Also if you want, you can have write access to the soc svn in which the
current j2k code is. (send diego a username for that)
