Implement loop for video (overlays)

[mifi]

like loopAudio. See #88 (comment)

Alternatively we can specify -ignore_loop 0 for gif inputs https://ffmpeg.org/ffmpeg-formats.html#toc-gif-1

Ok no problem, I took a look into the code and I succeed to made someting work.
There is just still problem because video stream is sudently closed when clip is over.
Could you take a look, maybe you know how to close it gently.
