 Reported by Osamu Watanabe <owatanab at es.takushoku-u.ac.jp>

 Decoding p1_03.j2k (a test codestream defined in the ISO/IEC 15444-4)
 returns the following warning:

 {{{
 [jpeg2000 @ 0x12d7079a0] Mid mismatch 1 in pass 18 of 22
 }}}

 This message comes from the lines:

 https://github.com/ffmpeg/ffmpeg/blob/2eb9c35010fe2c65a6d0f9a420332bca369c5ead/libavcodec/jpeg2000dec.c#L2045-L2049

 The cause of the warning should be investigated to suppress the warning.
