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.

Currently the file overwrite check does not work for paths that
contain a colon.
Use avio_find_protocol to always execute the existence check if
the file protocol is going to be used.
Fix remaining part of ticket #3249.
