this seems breaking the decoder

./ffmpeg -i matrixbench_mpeg2.mpg  -vcodec libopenjpeg -vframes 1 test.j2k

./ffmpeg -strict -2 -vcodec libopenjpeg -i test.j2k -f null -

[libopenjpeg @ 0x28f3220] Error decoding codestream header.
[j2k_pipe @ 0x28d1bc0] decoding for stream 0 failed
[j2k_pipe @ 0x28d1bc0] Could not find codec parameters for stream 0 (Video: jpeg2000, none): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options
test.j2k: could not find codec parameters

!HAVE_OPENJPEG_2_1_OPENJPEG_H=yes

!HAVE_OPENJPEG_1_5_OPENJPEG_H=yes
