Hi,

Trying to use captions but the example provided doesn't work for me.

OS: Ubuntu 16.04.4 LTS
Node version : 8.10.0
ffmpeg installed

node examples/captions.js

ffmpeg process started: ffmpeg -i /tmp/videoshow-b125f69d-eee3-4f45-88a4-096e61661544 -i /tmp/videoshow-c85a6426-715e-4248-a07d-c3f7b1c41d6e -i /tmp/videoshow-1f9f34a7-5c64-4c54-8350-36ac46a608f9 -i /tmp/videoshow-e0202044-23ee-4efb-a9fb-55969a2f1312 -i /tmp/videoshow-7923838d-d2c9-40f2-ae36-d9891e6db7d7 -y -filter_complex concat=n=5:v=1:a=0 video.mp4
