VideoWriter::get() always returns 0.0 #C++

asked 2017-08-30 06:23:42 -0600

Hello,

I'm working with OpenCV and I wanted to work with "videowriter::get()" and "videowriter::set()", but I don't know if it's posible. For example, while getting with "videowriter::get()" any property, the output always is cero. Is there any solution? Any other advice if I want to change dinamically the framerate of a video I'm recording?

Thank you.

both get() and set return a [0,1] value, signifying, if that property is supported on your box / opencv libs, also see here for valid enum values

and no, you cannot change the framerate dynamically like this, it is fixed.
