Hi, try to play around with kernel parameters and increase values for:
net.ipv4.udp_rmem_min net.ipv4.udp_mem net.core.rmem_default net.core.rmem_max net.core.netdev_max_backlog net.core.netdev_budget also check interface Ring parameters: ethtool -g [interface] and increase RX and TX to maximum: in my case: ethtool -G eth0 rx 4096 tx 4096 Check out this document: https://blog.packagecloud.io/eng/2016/06/22/monitoring-tuning-linux-networking-stack-receiving-data/ and enable RPS and RFS. This solved my problem with Circular buffer overrun when adding more instances. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
