4 NDI Sources per PC and using different sync methods.What we tried so far (and resulted in audio being de-synced (after a while >1 hour and faster <1 hour): Some scenarios de-sync more and faster than others. In the below scenarios we tried all different sync methods, Internal, Network and Source Timing, which still results into the audio being de-synced. We connect to the server using remote desktop with hardware graphics adapter enabled for remote sessions (which should resolve other rendering issues), however connecting without Remote Desktop and using a monitor with mouse and keyboard does result in the same issues.

The server receives roughly 250/350mbits of data, uses 20%-ish CPU and 25/30%-ish GPU. Both source PCs are using 10%-ish CPU and 15/20% GPU and are sending roughly 120/160mbits of data. For some reason, this is not the case using our setup.Īll 3 PCs are rather beefy and (should) have no issues regarding CPU or GPU limitations and are connected with a proper router on a gigabit network. Splitting everything into different sources should have, as other topics described, resulted into everything being synced properly.

We get no (or almost no) rendering issues or other dropped frames using this setup. All sources are sent to the server which does the rest and combines additional shared scenes. I duo stream with my girlfriend on one channel and mainly use NDI to send both of our PCs sources to a network server which encodes and sends to Twitch.īoth PCs have 4 NDI sources: 2 Video (Main Display capture 1080p (rendered down from 1440p native), Webcam capture 720p) and 2 Audio (Desktop Audio and Microphone). We are currently facing a strange audio delay (or out of sync) issue that requires some help after trying out various scenarios.
