Describe the issue

Hello.
I'm using your app as a video proxy. All paths are added via the API.

Describe how to replicate the issue

But additionally, I specified the following parameters in the configuration file

writeQueueSize: 524288
readBufferCount: 32768
udpMaxPayloadSize: 1472
protocols: [tcp]

and added in /etc/sysctl.conf

net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.ipv4.tcp_mem  = 8192 131072 16777216
net.ipv4.tcp_rmem = 8192 131072 16777216
net.ipv4.tcp_wmem = 8192 131072 16777216

Did you attach the server logs?

yes

But it still causes the loss of RTP packets and sometimes I see it in the logs

iptraf on an interface that deals only with video proxies

Did you attach a network dump?

yes

on proxy (iphost) with mediamtx 10502 to my vlc 60515
network card MTU 1500

sudo tcpdump -nn host iphost and not port 22

since the situation is hopeless, I decided to post rtsp links, maybe this will help

From the camer over Nat-router rtsp://94.31.247.14:5541/cam

From the mediamtx rtsp://593358:Zlbl9NMh96@87.249.58.76:10502/02c00081491be26a
