Playback Stutter #16

Open BlackFishMaker opened 2 years ago

BlackFishMaker commented 2 years ago

Whenever i try to play back a NDI stream on my Dicaffeine machine it always stutters no matter the resolution or framerate unless the incomming stream is a NDI HX stream. Weirdly enough if i use the Dicaffeine machine to screenshare a video to another device it runs lag free. The machine i use has a Intel Celeron N4000 with 8Gb of ram and runs on a fresh install of Xubuntu 20.04.01 LTS. Any idea what the issue could be?

Hi, N4000 should be fine for 1080p. Is the machine connected via cable or WiFi? Full NDI can use up to 100Mbps bandwidth.

Ive tryed both wifi and cable and neither worked but ive made another interesting discovery. I belive it has something to do with Unicast and Multicast NDI. Because if i send a NDI signal directly from vMix to Dicaffeine it stutters but if i transcode that same signal once with NDI Bridge as full bandwidth NDI it doesnt stutter with Dicaffeine. vMix does also send full bandwith NDI but i belive its Multicast while the NDI Bridge does Unicast.
