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
