Text overlay on ffmpeg stream, why not working?

Question

fmpeg

While doing

ffmpeg -f v4l2 -s 352x288 -i /dev/video0 -filter_complex "drawtext=fontfile=/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf: textfile=test.txt: y=25: x=25: fontcolor=red" -c:a copy http://localhost:8090/feed.ffm

Gives the following error:

Output #0, ffm, to ' localhost:8090/feed.ffm ':

What does this mean and how to overlay text on the stream.
