Comment:

 I tested current FFmpeg git head - e36916a - the version that introduced
 the regression - 3cfd4df - and the the version before 3cfd4df - e494f44 -
 with the following command line:
 {{{
 $ ffmpeg -f lavfi -i testsrc -threads 1 -vcodec libopenjpeg -t 3
 -compression_level 30 out.mov
 }}}
 The first and second output file look broken on playback, the oldest
 version (before the regression was introduced) produce an output file that
 plays fine. This is also reproducible with the native j2k decoder.

 I tested with openjpeg-1.5.0, since 1.5.1 is known to be buggy, I suggest
 not to use it for regression tests.
