You mean it does not work for 8bit yuv?
In this case, you have to fix this first.

Please look at this commit:
and test if Motion JPEG and DPX work like this.
If yes, instead of adding new options "bm_jpeg" 
and "bm_dpx", please add a new input_format 
option similar to the v4l2 option and deprecate 
bm_v210 (or make it an empty option).
