Hi, I currently try to stream my webcam to my browser and I want to display some text in the stream. It seems
ffserver does not handle -vf drawtext flags? I pass them to the ffmpeg command. If I use the ffmpeg command and use an output file instead of streaming to ffserver and I play this file I can see the text.

ffmpeg command:

ffmpeg -f v4l2 -input_format mjpeg -video_size 1920x1080 -i /dev/video0 -ss 00:00:05 -vf "drawtext=fontfile=/usr/share/fonts/freefont/FreeSerif.ttf:textfile=test.txt:fontsize=32 :fontcolor=white:x=(w-text_w)/2:y=(h-text_h)/2" http://localhost:8090/feed1.ffm
