[FFmpeg-user] how to set bitrate for h264 webCam when using ffmpeg

[Soho Soho123]

Hi all,

Is there any option for bitrate setting when using ffmpeg.
for example:
ffmpeg command line :
ffmpeg  -loglevel debug -f video4linux2 -r 10 -s 640x480 -input_format
h264 -i /dev/video1  -vcodec copy http://localhost:8090/feed1.ffm

I can set frame rate, input format, video size,
can I set bitrate ?

Does anyone have idea?
