i did several tests over long time with different pc‘s either on internal network or over the internet.
i was never able to have a stable system, as it would be needed for a broadcast situation.
since the testresults where much worse with vmix, i did the tests with ndi monitor.
i did the tests with all ndi versions, up to 5.5xx
also changed the vmix ndi dll to the actual bridge version.
Paperspace cloud with nvidia gpu, acting as bridge,
all clients where out of sync (audio-video) in short time, <30min
client x299, 10900, rtx4000
tested with all options, h264, h265: low and medium bw.
internal network, gbit
bridge on the x299
client1 on hp g3 laptop, quadro m3000
client2 dell precision,i7?, quadro p2200
both clients stopped several times unexpected, audio out of sync.
i changed test2 to another bridge with a xeon?? and a rtx5000
i changed test 2 to another network
running several times, over 24 hours, both clients where always down, next day
xeon as bridge
client hp g3 laptop over 5G mobile gsm router (250mbits up and down)
in short time, signal was interrupted and or out of synch.
i did tests with all the same hardware, with SRT miniserver, acting as relais, all testcases where running rocksteady stable over a few days.
disadvantage of the SRT solution, costs and latency.
i still hope, that someone else can show me a working ndi bridge system, in my environment🙂
