Some clarification first, by setting `-f flv`, you are generating a FLV
format output not a raw H.264 bitstream. And since you are copying the
video stream, bitrate, output rate, (video) encoding presets won't have an
effect.
You can try specifying two outputs:
ffmpeg -f v4l2 -input_format h264 -video_size 640x480 -framerate 30 -i
/dev/video0 -f flv -vcodec copy /home/pi/recordonly.flv -vcodec copy -f
flv rtmp://x.x.x.x:1935/my_url
