Hi, I am trying to convert a sequence of exr image to mov but got an error. 
The image is generated from a vray render. I have read the documentation
and ffmpeg says it is able to decode EXR. 

Any help would be appreciated and if you need more information, 
please let me know. Thank you. 

Below is a test when I run on a single exr

>> ffmpeg -i hairyball.0101.exr out.mov

hairyball.0101.exr: Invalid data found when processing input

That is the error message I got

>>mediainfo hairyball.0101.exr
