[FFmpeg-user] generate a poster image with ffmpeg

[chovy]

When I add the poster flags my output looks like this:


frame= 3 fps=0.0 q=-0.0 q=-1.0 size=N/A time=00:02:44.53 bitrate=N/A speed= 1

Without these flags it looks like this:

frame=24134 fps= 31 q=-1.0 size=N/A time=00:13:25.22 bitrate=N/A

http://www.catb.org/esr/faqs/smart-questions.html#beprecise helps a lot
because it saves answers "try this and that" when you already tried
"this and that"
