> 
> OpenVINO APIs require specify input size to run the model, while some
> OpenVINO model does accept different input size. To enable this feature
> adding input_resizable option here for easier use.
> Setting bool variable input_resizable to specify if the input can be resizable or
> not.
> input_resizable = 1 means support input resize, aka accept different input size.
> input_resizable = 0 (default) means do not support input resize.
> Please make sure the inference model does accept different input size before
> use this option, otherwise the inference engine may report error(s).

>       model=model_name.xml:input=input_name:output=output_name:\
>       options=device=CPU\&input_resizable=1 -y output_video_name.mp4
