I forked the code on github here : https://github.com/up4/FFmpeg
I renamed libavcodec/exr.c into libavcodec/exrdec.c.
I based the structure on the png codec.
I tried many modifications everywhere in the repository to get the configuration process to include "exr" in the list of enabled encoders, but I couldn't manage. Can someone tell me where I need to make modifications for the exr encoder to register. Also, if someone could have a look at what I did just to check if I'm on the right track.
For now, I will prototype all this using the official ILM OpenEXR library (after enquiring to their mailing list I found C exports there, actually). And then, when the mockup works, I will try to write standalone code within the FFMPEG code itself.
