Are you sure that there is a file CapturedImage-000.raw ?
You forgot to specify the input pixel format.
Many parameters are missing for the raw output. But the error message is 
from the input.

Do you really want raw video? That's not the easiest format for a beginner.
Everything must be specified for the input (file format, pixel format, 
size, framerate, and whatever I may have forgotten...) and the same 
things must be specified for the output again.
