[FFmpeg-devel] Jai Menon: How to use libopenjpeg wrapper for jpeg2k decoding?
Thu Jan 29 16:27:42 CET 2009
Your FFmpeg post about your FFmpeg patch for jpeg2k decoding was
forwarded to the OpenJPEG group. I am learning ffmpeg and VLC with the
goal of making a motion JPEG2000 video player. I hope you might share
your progress with using libopenjpeg in ffmpeg. I had some questions:
Can you give me an example on how and what it can be used for?
Will it work on motion video that is jpeg2k encoded or only stills?
How is a patch applied ( sorry I am working on Linux but I am new to
this OS )?
Is a patch a source code merge or a binary merge that you apply over the
current ffmpeg version source or binary?
Thanks in advance,

This has proved useful for debugging the soc code and hopefully for
other purposes as well.
The code itself is meant for review but the buildsystem part is mostly
rfc. I don't know if building ffmpeg/lavc with
openjpeg support makes it unredistributable.
Also, I have tested this only with jpeg2k conformance suite since my
last attempt to download a R3d file failed
miserably :-) It would be interesting to know if those work as well.
