I'm using the current code to create a video with some text of several lines. When executed I'm receiving a video with the text joined vertically because of lacking space. How do I do to add line-height space? 

ffmpeg -i videoInput.mp4 \
       -vf drawtext="./font/Roboto/Roboto-Bold.ttf: \
           text='testing text \ntesting text \ntesting text':\
           fontcolor=yellow:\
           fontsize=36:\
           box=1:\
           boxcolor=black@0.5: \
           boxborderw=160:\
           x=(w-text_w)/2:\
           y=(h-text_h)/2"\
    -codec:a copy \
    videoOutput.mp4

To increase the line-height add a line_spacing parameter to the command,(http://ffmpeg.org/ffmpeg-filters.html#drawtext-1) So it looks like:

ffmpeg -i videoInput.mp4 \
       -vf drawtext="./font/Roboto/Roboto-Bold.ttf: \
           text='testing text \ntesting text \ntesting text':\
         line_spacing=30:\
           fontcolor=yellow:\
           fontsize=36:\
           box=1:\
           boxcolor=black@0.5: \
           boxborderw=160:\
           x=(w-text_w)/2:\
           y=(h-text_h)/2"\
    -codec:a copy \
    videoOutput.mp4

Or

Some trick is to append a double breakline on the desired text. It would look like:

  text='testing text \n\ntesting text \n\ntesting text'

ffmpeg -i videoInput.mp4 \
       -vf drawtext="./font/Roboto/Roboto-Bold.ttf: \
           text='testing text \n\ntesting text \n\ntesting text':\
           fontcolor=yellow:\
           fontsize=36:\
           box=1:\
           boxcolor=black@0.5: \
           boxborderw=160:\
           x=(w-text_w)/2:\
           y=(h-text_h)/2"\
    -codec:a copy \
    videoOutput.mp4
