increase the size of the real-time buffer.

Hi, I am streaming windows directshow desktop capture via udp and I am getting occasional "real-time buffer 155% full! frame dropped!" errors, which are causing audio ( and rarely video ) glitches. Is there a way to increase the size of the real-time buffer ? I am willing to get higher latency if it will solve the frame drops. This is my command: -f dshow -i video="screen-capture-recorder":audio="Stereo Mix (IDT High Definition" -vcodec libx264 -preset ultrafast -tune zerolatency -r 10 -async 1 -acodec libmp3lame -ab 24k -ar 22050 -bsf:v h264_mp4toannexb -maxrate 750k -bufsize 3000k -f mpegts udp://192.168.5.215:48550
