Hi Michael,

I tested the decoder with few jp2 files. i decoded the jp2 files to yuv
format. Apparently, it seems working. Could you please little bit specific
about the errors when you tested? Also, i want to know with which reference
codec will i compare? If you would give more information about the process
bug finding, that would be great help for me.
