#1949: Display frame number on each frame
--------------------------------+---------------------------------------
Reporter: igorg | Type: enhancement

--------------------------------+---------------------------------------
Summary of the bug: The drawtext filter understands the n variable in the
"y=h-(2*lh)-n", but if I want to display the frame number on each frame as
text, then it does not work. Putting n there displays the letter itself
and %n is the new line symbol.
How to reproduce:
{{{
% fmpeg -i in.mov -vf "drawtext=fontfile=/usr/share/fonts/ttf-bitstream-
vera/Vera.ttf: x=(w-tw)/2: y=h-(2*lh)-n: fontcolor=white: fontsize=40:
box=1: boxcolor=0x00000000 at 1: text=" -an -y out.mov
ffmpeg version 0.10.6
built on Nov 21 2012
}}}
