EXR files have, like tiffs, multiple channels and layers. I have a
patch for exr.c that allows you to select the layer you want to process
thru a -layer flag. It is not bulletproof but works for all layers that
have 3 channels in them (normals, motion vectors, etc).
The calling convention for ffmpeg is:
ffmpeg -layer Diffuse -i myexr.%d.exr test.mov
Here's an exr image with multiple layers:

The advantage of this is that the is32x32 division branch in
decode_coeffs_b is removed from the inner loop to outside the block
coef decoding loop in decode_coeffs. Also, it allows us to merge the
txsz branches from the block coef decoding loop, the context merge
and the context split.

I found the optimisation of 2 samples per iteration obscured the
underlying algorithm. I had to write it out on paper and translate into
a mathematical sum to see that the two samples are unconnected. I hope
that if anyone else is struggling to understand the code that this will
be useful.
