I want to make a UVC camera with changable frame rate via USB Control. However, AN75779 How to Implement an Image Sensor Interface Using EZ-USB® FX3™ in a USB Video Class (UVC) Framework example, frame rate is defined and constant for camera.
I have a external microcontroller to control frame rate. Can I control the frame rate not by uvc but only fval signal of sensor?
(For example sensor starts fval in every 20-30 ms which means that 33-50 fps but defined uvc frame rate is 60 fps can I get 33-50 fps for system or not?)
