It is clearly apparent to me I don't understand something going on
here!
I clearly select an output framerate of 7fps.
My camera's set to limit each connection to 7fps (and I have verified
it is doing so).
The camera I am using is a high end AXIS quite capable of 60fps.
Resultant videos are the full 3600 seconds, but they play in 900
seconds!
Verified via time time stamp on the images and vlc's playtime.
Why is fps=2.0? Totally not what I selected, nor what is provided by
camera.
Why is drop=1320. The machine doing this is quite capable of the full
framerate.
What am I missing?
Thanks in advance
