I have a LED wall that utilizes three 1080p50 processors. On top of that I need a 1080p50 feed to run in sync with the LED wall. So I made a custom screen size that is 6144x1080 (two processor doesn’t use the full width)in size and using layer routing and fill to the send the picture to the other four outputs. The problem is that as soon as I make the second route the video starts to lag. I’ve tried both h264 and h265 encoding and h265 give a slightly lesser lag. The server runs latest beta.
Ubuntu 18.04.3 with kernel 5
GeForce GTX 1660
2x Deklink duo 2
I have a nvme drive in the server that I haven’t tested yet, but since it plays without issues on one channel I don’t think that is the issue. Looking at
top the processor isn’t working hard at all.
All outputs have 6 frames in buffer and I even tried to add the
BUFFER 5 to the route command without luck.
