ffmpeg - How to stream rawvideo x11grab desktop with zero latency -

i stream linux desktop ffmpeg rawvideo use command on server:

sudo ffmpeg -f x11grab -s 1280x720 -i :0.0 -vcodec rawvideo -pix_fmt bgr0 -threads 1 -f mpegts udp://localhost:1234

its take 900mb/s bandwidth on lan dont wanna use codecs cause create big latency playing games.

but cant use ffplay recognize stream

ffplay 'udp://localhost:1234?fifo_size=999000&overrun_nonfatal=1'

i got error: failed open file 'udp://localhost:1234?fifo_size=875000&overrun_nonfatal=1' or configure filtergraph
