Amiga IFF ILBM image format support

muadib3D
Hi,

I was wondering if ffmpeg supports an option for Amiga IFF ILBM 24 image
loading/saving?
(Found some dated posts regarding this but ffmpeg does not understand the
extension of the format)

If not, how can I file a feature request for this?

Thanks in advance,

muadib3D

Reference: https://en.wikipedia.org/wiki/ILBM
a GIMP IFF-ILBM plugin: https://blitterstudio.com/gimp-iff-plugin/

FFmpeg does not believe in extensions / command line
and complete, uncut console output missing.

Hi Carl,

Here is a 24bit ILBM file:
medieval-castle-3d-model-max-fbx-ma-mb-tga.iff
<http://www.ffmpeg-archive.org/file/t379595/medieval-castle-3d-model-max-fbx-ma-mb-tga.iff>  

and the same image in TIFF format:
medieval-castle-3d-model-max-fbx-ma-mb-tga.tif
<http://www.ffmpeg-archive.org/file/t379595/medieval-castle-3d-model-max-fbx-ma-mb-tga.tif>  

Thank you!

What does not work with this file using FFmpeg /
command line and complete, uncut console output missing?

(This version is quite old, but that's not the point.)

ffmpeg indeed doesn't support muxing to the IFF format, nor encoding to
ILBM.

A feature request for this already exists, but noone seems to have
contributed code yet:
https://trac.ffmpeg.org/ticket/1048

Cheers,
Moritz

Yes, you are welcome to implement it.

Hi all,

The Amiga community would be immensely grateful for this!
Also, I would gladly mention the FFmpeg team and the programmers that would
be involved in this on the credits of my webcast on twitch.tv/muadib3d!


Thanks in advance,
