The problem is that as soon as the EXR is read, the data is discarded in 
favor of a uint32_t.
Modifying that requires modifying all the read routine and making the 
video filter take a float, which seems like it is not easily done.
The patch is a hack but a useful one which makes EXR and ffmpeg really 
productive with each other.
