As low network buffer sizes can cause frame loss, it is advisable to increase them to double of frame size. That is 8MB for HD and 32MB for 4k. To do this:

  • Add the following lines to file /etc/sysctl.conf

`#Extended network buffers for UltraGrid

net.core.wmem_max=8388608

net.core.wmem_default=8388608

net.core.rmem_max=8388608

net.core.rmem_default=8388608

  • Run sysctl -p to apply the changes
