* Increase number of runs to ensure good results

* Add ffprobe endpoint

* Get ffprobe for multiple inputs

* Copy ffprobe in output

* Add fps to camera metrics

* Fix lint errors

* Update stats config

* Add ffmpeg pid

* Use grid display so more cameras can take less vertical space

* Fix hanging characters

* Only show the current detector

* Fix bad if statement

* Return full output of ffprobe process
