You can take a look at the pixel format (pix_fmt) value of the video 
stream. To map the pixel format into bits-per-pixel use the table 
printed by "ffprobe -pix_fmts". Or for more information about the pixel 
formats including the bit-depth per components use "ffprobe 
-show_pixel_formats -print_format json".
