 Summary of the bug:
 The test JPEG2000 is source from openjpeg conformance test set and can be
 decoded correctly by openjpeg commend line. it is a signed JPEG2000 code
 stream, i.e.,
 {{{
 ./j2k_dump -i ./p0_08.j2k

 [INFO] tile 1 of 1
 [INFO] - tiers-1 took 3.264204 s
 [INFO] - dwt took 0.268017 s
 [INFO] - tile decoded in 3.696231 s
 image {
   x0=0, y0=0, x1=513, y1=3072
   numcomps=3
   comp 0 {
     dx=1, dy=1
     prec=12
     sgnd=1
   }
   comp 1 {
     dx=1, dy=1
     prec=12
     sgnd=1
   }
   comp 2 {
     dx=1, dy=1
     prec=12
     sgnd=1
   }
 }
 }}}

 However, ffmpeg wirg -vcodec libopenjpeg produce wrong color output

 How to reproduce:
 {{{
