FFmpeg - One Source for multiple motion sensors

Hey there,

is it possible to have multiple FFmpeg Motion Binary Sensors with the same source/ input.
And if so, will the camera image be grabbed individually for each Motion Sensor or will the motion detection be performed on the same (cached) image?

The reason is I have an wide angle camera observing and want to track movement directions. Do put it simple I want to check if someone goes from left to right or from right to left.
And I prefer a solution which doesn’t put to much load on the camera or pi.

Thanks.
