Hi All
I have ffmpeg running in one instance streaming to udp on the local host
Ffmpeg is running in another instance, also on local host, and reads the
stream from udp
Why does it take 5 - 10 sec for the second instance to pick up the udp
stream ?
I seem to be getting a lot of "Current profile doesn't provide more RBSP
data in PPS, skipping"
First instance - streaming to udp:
ffmpeg -loop 1 -re -i overlays/test.png -c libx264 -preset ultrafast -r 24
- pix_fmt yuv420p -g 1 -f mpegts udp://t420.netmaster.dk:8001
