Hi,
I'm having trouble getting ffserver & ffmpeg working with drawtext. I
receive the error "av_interleaved_write_frame(): Broken pipe" and then
ffmpeg stops.
ffserver configuration:

ffmpeg command:
ffmpeg -v debug -f alsa -ac 2 -i hw:1 -f video4linux2 -i /dev/video0 -r 30
-s 320x240 -filter_complex
"drawtext=fontfile=/usr/share/fonts/truetype/freefont/FreeSerif.ttf:
