ive just tested your jpeg2k codec:
ffmpeg -i tests/data/a-ljpeg.avi -vcodec j2k -f image2 -qscale 10 -pix_fmt rgb24 tes10t%d.j2k

(tests/data/a-ljpeg.avi as available after make test)

and
for i in `seq 1 50` ; do jasper --input tes10t$i.j2k --output tes10t$i.pnm ; done

jasper only decodes some of the files, this should be fixed

also from the 23 reference codestreams it decodes only 2
(i got the codestreams from:
http://www.crc.ricoh.com/~gormish/jpeg2000conformance/j2kp4files_v1_5.zip)
