error messages with straightforward setup

[vladpetric]

Hi,

I have a straightforward setup with a sender on an Rpi3 with Ubuntu 22.10, (built from source with speex disabled), running as follows:

~/bin/roc-send --input=alsa://hw:CARD=Receiver,DEV=0 --source=rtp+rs8m://192.168.1.231:10001 --repair=rs8m://192.168.1.231:10002 --control=rtcp://192.168.1.231:10003 -v --no-resampling --rate=44100 

And a receiver running on an x86_64 box (Ubuntu 22.04, also built from source, with speex disabled), as follows:

~/bin/roc-recv -s rtp+rs8m://0.0.0.0:10001 -r rs8m://0.0.0.0:10002 --control=rtcp://0.0.0.0:10003 --output=alsa://default -v --rate=44100  --no-resampling --sess-latency=120ms   -v

Nothing out of the ordinary (AFAICT) on the sender side, but on the receiver side I get a lot of:

Any thoughts?

I do get some late packages too, but that I feel is normal. The bad version happens irrespective of that:

Apologies, it seems that something else was firing packets on the same port(s). I changed the ports to something more random and the problem disappeared.

Thanks for sharing solution :)
