I was going through the bug tracker for a list of bugs associated with
jpeg2000. Looking at issue 5012, is there a good utility for solving
this issue? To whomever it may concern, please do let me know your
opinion on this.

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.

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

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
