Hi,
I saw the list of unmentored projects for GSoC and enhancements to the
JPEG2000 decoder and encoder were there. I am finding it very
difficult to make a proposal as the specifications are not available
for free. However, I am willing to work on improving the JPEG2000
features even if it is not
. Would that be a good way to start?

Hello,
I had gone through ticket #7445 and it mentions about JPEG2000 parser.
What exactly does a parser do and how is it different from a decoder?
I am unable to understand the exact use case of a parser.

Hi,
I am trying to decode the p1_03.j2k reference file. However, while
trying to use libopenjpeg instead of the native decoder, I get the
following error,
[libopenjpeg @ 0x55f249d7e180] Unable to determine pixel format.
The exact command run was:
ffmpeg -vcodec libopenjpeg -i p1_03.j2k -f framec

Hi all,
I am working on the JPEG2000 decoder. However I am having trouble
understanding pixel formats correctly.
For example, from my understanding, the reference file p1_01.j2k pixel
format does not get recognized by the native decoder. When I force a
gray8 format on it, I am able to get output s

Hello,
JPEG2000 uses .pgx format for conformance testing. Is it a good idea
to allow the ffmpeg
native decoder to have an option to dump .pgx files? This would help
with testing additions
to the code.

Hello,
I wish to contribute to ffmpeg and though of submitting a small patch
to fix a bug listed on the bug tracker. However, my patch submission
does not reach the mailing list. I have checked all the instructions
and use git format-path with git send-email. What should I do?
