JPEG2000 encoder produce corrupted output

[inganault]

The JPEG2000 encoder produce output image with apparent artifact for some input files.

How to reproduce:

ffmpeg -i corrupt_j2k.y4m test.jp2 && ffmpeg -i test.jp2 test.jpg

The file corrupt_j2k.y4m (yuv420p) is attached.
Converting the corrupt_j2k.y4m to yuv422p and yuv444p also trigger the bug.

What I have tried:

Encoder	Commit	Status
libopenjpeg	b4eca5c (git-master)	not affected
avcodec jpeg2000	b4eca5c (git-master)	affected
avcodec jpeg2000	341064d (libavcodec/jpeg2000: fix tag tree reset)	affected
avcodec jpeg2000	f0e3311 (libavcodec/j2kenc: Support for multiple layers)	not affected

So what you are saying is 341064d68a134e2fb3dd35f8f5b50c6df8506c10 is the regression commit cause previous commit is not affected. Lets check openjpeg decoder with your output (it is bitperfect with mine, except for one byte in ffmpeg version).

ffmpeg.exe -c:v libopenjpeg -i defchwae.jp2 cxanvcadcv.png

Produces same corrupt output, in fact so does opj_decompress.exe -i corrupt_j2k.jp2 -o fasfafas2121.png

So the bug is in encoder.

Here [jpeg2000 @ 00000292f9557740] bpno became invalid is no longer present after the fix here (in encoder, so need to encode again files): #5360

but the bug is still there.

Also you can use ffmpeg.exe -i corrupt_j2k.y4m -pred 1 tes231231t.jp2
