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.
test 1
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.
test 2
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
same result,
i changed test 2 to another network
same result
running several times, over 24 hours, both clients where always down, next day
test 3
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🙂
