Comment (by jminor):

 Pixar is interested in this as well.

 Looking at the code in exr.c it appears that ffmpeg does not use
 libopenexr, but rather has a reimplementation of an EXR decoder. Is this
 negotiable, or is that by design?

 In either case, we would like to understand how much work it would be to
 add support for the dwaa compression scheme to ffmpeg's exr reader. Is
 this a simple change, or a substantial amount of work? We could possibly
 help out with this, although we don't have anyone familiar with the ffmpeg
 code base at the moment.
