for a FFMPEG INPUT PARAM it's irrelevant what the driver supports - it 
don't tell the source driver anything but tells ffmpeg to ignore it's 
auto-detection

it's the same with "-f" as input param when the source has some weird 
wrong header

it *really* would be helpful when you post uncutted command line and the 
whole output instead all of this guessing back and forth
