 Looks there is some mistake in EXR format support in ffmpeg.
 I`m tried to convert simple exr image file to jpeg, but get funky-noissy
 image as result :
 [[Image(http://i112.photobucket.com/albums/n173/russiaman/tmp/test_exr_out.jpg)]]

 Exact the same noisy image is appear, when i`m try to view exr file via
 ffplay.

 there is a commandline i`ve used to convert:
 ''ffmpeg.exe -f image2 -i d:\tmp\test_exr.exr
 d:\tmp\sq2mv\test_exr_out.jpg''

 in console i get one message many times:
 ''[exr @ 0000000001e60940] Line offset for line 804 is out of reach
 setting it to black''
 there is a screenshoot:
 [[Image(http://i112.photobucket.com/albums/n173/russiaman/tmp/ffmpeg_exr_bug.jpg)]]

 In attachments i put my source exr file and output jpg generated by
 ffmpeg.
