it seems libopenjpeg is not able to decode the files generated with
libopenjpeg.
That is with the libopenjpeg from ubuntu 12.04 (1.3+dfsg-4+squeeze2build0.12.04.1)
but ubuntu 14.04 ships a variant of 1.3 too

test done with:
./ffmpeg -threads 1 -i matrixbench_mpeg2.mpg -vframes 1 -vcodec libopenjpeg -format j2k test.j2k
./ffplay -vcodec libopenjpeg test.j2k
