For that case it definitely DV file with proper file extension... May be 
it has sense to increase ratio value according to minimal DIF sequence 
marks/headers found at least in one frame of stream?

I always thought that format detection for ffmpeg is prioritized in way:
1. "-f <format>" input format redefinition
2. input file extension
3. stream probe
Why does it perform stream probe if input file extension is defined?
