Yes.  N.x, N.y, and N.z are lowercase so you won't get a match.  You 
might get a match with "-layer P_world" as that, strangely, has the 
channels in uppercase.

You should go to ffmpeg-devel at ffmpeg.org where I posted a patch (look 
for the email "libavcodec/exr.c: Made channel names case insensitive").  
You then need to recompile ffmpeg with the patch applied.

The patch is waiting review for approval and if it is rejected you won't 
get it in any version of ffmpeg.  If it is approved, you may see it show 
up in a week or so from the time of approval on ffmpeg.zeranoe.com for
