(io) un-pause io/video/SFrameGrabber on successive startCamera calls
Description
- Currently calling the startCamera slot, when the camera is started and paused, does not un-pause it
- I propose to un-pause it in this specific case
Proposal
- Un-pause the camera if it is started, paused and startCamera is called
Functional specifications
- Allow camera start to un-pause it if it is already started
Technical specifications
- Un-pause the camera at the beginning of the startCamera function
Test plan
Make sure the startCamera restarts the camera when it is paused
