How do I make a gif with text over frames

Question

I'm currently converting a video to a gif with the following command (taken from this example)

ffmpeg -y -ss 30 -t 3 -i input.flv \
-vf fps=10,scale=320:-1:flags=lanczos,palettegen palette.png

ffmpeg -ss 30 -t 3 -i input.flv -i palette.png -filter_complex \
"fps=10,scale=320:-1:flags=lanczos[x];[x][1:v]paletteuse" output.gif

What I'm trying to accomplish is have text show on the top of the gif while it plays but I'm slightly confused as to how I add in the command below tweaked from this example

drawtext="fontfile=/path/to/font.ttf: \
text='Stack Overflow': fontcolor=black: x=160: y=-1"

You would insert it after the scaling but before the palette filters.

ffmpeg -y -ss 30 -t 3 -i input.flv \
-vf fps=10,scale=320:-1:flags=lanczos,drawtext="fontfile=/path/to/font.ttf: \
 text='Stack Overflow': fontcolor=black: x=160: y=-1",palettegen palette.png

ffmpeg -ss 30 -t 3 -i input.flv -i palette.png -filter_complex \
"fps=10,scale=320:-1:flags=lanczos,drawtext="fontfile=/path/to/font.ttf: \
 text='Stack Overflow': fontcolor=black: x=160: y=-1"[x];[x][1:v]paletteuse" output.gif

Do I have to add it to both loops or just one? – nadermx Oct 27 '16 at 17:59
Strictly speaking, just the 2nd, but the quality will be worse, since the palette won't have accounted for the text. – Gyan Oct 27 '16 at 18:41
I'm having a issue when I run the second pass where it doesn't detect the font file, but the first pass does? – nadermx Jan 19 '17 at 21:26
added a edit to fix the command – nadermx Jan 19 '17 at 21:43

@nadermx The command as written works here on Win 7. I think the use of quotes is shell-specific. – Gyan Jan 20 '17 at 05:31
