Looks good, for the other two, I may need to check with a problematic
sample I had to see if it works
Kind regards,

if the problem you are trying to solve is upsampling, the agreed samples
are usually 422,444 and 420 (Y,Cb,Cr order) but there can be files with
sampling factors like 242, since the jfif spec isn't to restrictive on what
sampling factors are allowed,libjpeg(and it's cousin libjpeg-turbo) support

Sounds like a good idea,

Hi
For bit-reading,
1. The spec has some chunks read from back to front,I didn't see that
functionality present in get_bits.h(which I assumed contained the bit
reading API).
2. It doesn't handle unstuffing correctly.
3. Doesn't handle EOB correctly, the spec has some arrays when there are no
more

There is one with way better performance on its way, especially with images
with magnitude refinement passes.
here @https://github.com/etemesi254/FFmpeg/tree/my-profile
And the associated runtime profile from running
`perf record -g -F 999 ./ffmpeg_g -i ~/jpeg2000/meridian.ht.j2c -v 32

Not sure what µ_start here relates to, but this is the zero bit plane
information in *B.10.5*
of the jpeg2000 spec (ITU Rec. T.800 (06/2019))

For the circular reference, I forgot about inclusion guards, sorry about
that.

This patch adds support for detecting Part 15 codeblocks to JPEG2000 specified
in (Rec. ITU-T T.814 | ISO/IEC 15444-15).
The decoder on detecting Part 15 codeblocks now fails gracefully with a
