See here for more details on the available compression options and raw bandwidth usage. Try to stay lossless with QOY, and if that doesn't work you can always pick JPEG, which is still mostly visually lossless. If you're on a standard 1G network you will likely need to use compression to keep bandwidth needs in check. It might also be feasible if you only transmit a feed with low resolution and/or low FPS or if you're on a 5G or 10G network.

It's also very hard to predict how any solution will perform for any given setup, so it's best to test it out and play with the settings.Ĭompression optionsYou want to pick raw transmission (simply don't select any compression) if you stay within the same computer (Named Pipe connection setting), because available bandwidth is not an issue in this case and you can save on CPU usage. What works best in a given scenario depends (among other things) on the specific use case and available resources.

Optionally a fixed delay between sender and receiver can be configured, which can be useful if outside audio or video sources need to be synced with the transmitted feed.īeam basically aims to offer more options, flexibility and stability, however, in the end no solution is better or worse in general, it's just different tradeoffs regarding CPU/GPU usage, bandwidth needs, quality, ease of use and compatibility.

Also only Beam offers a frame buffer on the receiver that is able to compensate for network jitter and packet loss, which can be a big advantage in some scenarios, especially when trying to use this on unstable networks like Wifi (note that using Wifi for this kind of transmission is still not recommended and should be avoided if possible). Using this makes it possible to achieve both lower bandwidth and CPU usage than NDI, but this may depend on the content and other factors.īeam also offers lossless compression options, including some that support alpha channels and HDR, which is not available in either NDI or Teleport. The JPEG compression that Teleport uses is also available in Beam, but with the additional option to only compress a certain percentage of frames, giving a fine grained control over the CPU usage vs.

The most common scenario would be transmitting audio and video feeds from OBS on a gaming PC to OBS on a streaming PC, another would be to run two OBS instances on the same PC, one for recording with a higher quality setting, and then transmit the video feed to a second OBS instance for streaming with lower quality, which adds some panels, alerts, animations and other effects only for the stream which shouldn't be visible in the recording (other solutions to achieve that currently don't seem to be really stable).ĬomparisonBoth NDI and Teleport can only transmit their video feeds using a lossy compression (albeit almost visually lossless to be fair). The video feed can be compressed lossy or lossless, or even transmitted raw with no added compression CPU usage at all but at the expense of extreme bandwidth needs. OverviewThis plugin transmits a video and audio feed from one OBS instance to another. binary build created on Ubuntu 20.04 WSL environment, therefore linked against glibc 2.31.
