The camera back-end for the `freemocap` project - or - An easy and efficient way to connect to one or more cameras and record synchronized videos💀📸
Poked around with the timestamps - run fast_camera_capture/example/framerate_diagnostics.py to see
In general things work smoothly, but the it looks like the cameras are dropping every other (or every third?) frame.
This is what it looks like with 3 cameras:
The behavior looks roughly the same with 7 cameras
When only using a single camera, connecting the dots in the 'frame duration' plot shows that (roughly) every other frame is double duration (i.e. 66ms instead of 33ms)
This suggests that every other frame is being dropped?
