Module FPS decrease when restarting sources

[denisvmedyantsev]

I used 4 videos (30+30+25+25=110 FPS) and a dump module

FPS logs on start

video-source-camera-1-1  | Processed 1000 frames, 30.05 FPS. Source location: /data/cam1.mp4.
video-source-camera-2-1  | Processed 1000 frames, 29.89 FPS. Source location: /data/cam2.mp4.
