Do you mean CinemaDNG? That's not the same as DNG. DNG is a file format 
for RAW still images, while CinemaDNG is for videos.
FFmpeg has an undocumented decoder for DNG images, but it's in an early 
experimental state and doesn't work with most images (in fact, I didn't 
find any DNG image that could be decoded correctly).
I don't know if FFmpeg has a decoder for CinemaDNG.
