Hi all,
As with last year, Michael asked me to help coordinate the creation of
grant request to the STF:
https://trac.ffmpeg.org/wiki/SponsoringPrograms/STF/2025
The objective remains to unlock funds for individuals that are
interested in contributing to the FFMPEG codebase.

You will need to add "c1p1_04-0.j2c" [1] to

The following no longer return a UB warning after the patch:
./configure --extra-cflags='-fno-sanitize-recover=undefined'
--toolchain=gcc-usan

Hi all,
Osamu and I are looking at adding FATE tests that checks that the MSE
of a decode image compared to a reference image does not exceed a
conformance threshold (see [1]).
Is there a precedent for adding small shell scripts along the lines of
the following to FATE?
https://gist.github.com/p
an then apply the conformance requirements
specified in the standard?

The patch LTGM with the following nits:
- the commit message width
- an extra empty line in decode_refpass()
Both can be fixed at merge time.
A larger question, which is probably best left to later or never, is
whether we care that the compression ratio has been changed for a

Looks like a nice improvement. It looks like the size of the
codestreams obtained when running `-q: 20` are larger after the patch
-- maybe related to the change in the step size calculation, which is
now the same for both bitexact and non-bit-exact. Is that expected? I
realize `-q` is arbitrary bu

Hi Osamu,
Below are suggested improvements to error messages.
There are also a couple of errant trailing white spaces in jpeg2000htdec.c.

Would this patch be an opportunity to set `cpl->content_title_utf8` to
an empty string at fill_content_title() at libavformat/imf_cpl.c if
xmlNodeListGetString() returns NULL? It could be done as a separate
patch alternatively.

Couple of follow-up comments.
- "mxf_parse_jpeg2000_frame" could be moved to one of jpeg2000 source
files, to keep J2K parsing code together. Maybe there is a way to
