I think the question is out of topic for this patch proposal, as this 
question is global for all flavors of DPX (also the ones already 
supported by FFmpeg, i.e. FFmpeg already supports RGBA 12-bit filled 
with Method A, here I just add the support for packed content, without 
adding anything else about alpha support in FFmpeg, this patch changes 
nothing about alpha support in FFmpeg and/or DPX) and the need for 
validating such patch is about sample files for RGBA 12-bit packed (RGBA 
12-bit filled with method A being already available) and not for the 
content itself.

If it is blocking for the patch inclusion, I could remove the line 
permitting RGBA Packed decoding.
