[FFmpeg-user] correctly escaping text in drawtext

Fri Mar 22 19:56:44 CET 2013

here's an example of 3+ levels deep of quoting/escaping for a draw text overlay…

ffmpeg -y -f mpegts -i  input.ts  -vf "scale=360:240,drawtext=fontcolor=red:box=1:boxcolor=0x00000000 at 0.7:fontsize=14:fontfile=/usr/share/fonts/truetype/freefont/FreeSans.ttf:expansion=normal:timecode=11\\\:30\\\:00.00:r=29.97:text=' | A Very Nice Show (PDT) '"  pro.mp4
