Yes, one OBS setup can send the same relaxation programme to two YouTube live events using the Multiple RTMP Outputs plugin, if the plugin works with your current OBS version and your channel is within YouTube’s limits. That duplicates one broadcast; it does not establish that one OBS instance can reliably create two different programmes with separate pictures or sound.
The practical distinction is whether you want two destinations for one feed, or two independently composed streams. The first has a supported setup path, with compatibility, bandwidth and platform checks. The second needs separate verification before you plan a live broadcast around it.
What ‘two streams’ can mean
“Two streams” can describe two different arrangements. You might want the same loop of rain, music and a static title card to appear in two separate YouTube events, perhaps for separate channels or audiences. Or you might want one event to show a temple scene and another to show a study-room visual, each with different audio. Those are not the same technical job.
With a duplicated output, OBS produces one programme and sends it to more than one RTMP destination. Each YouTube event receives the same picture and sound. A scene change in OBS changes the programme being sent; you should not assume that each destination can choose its own scene or audio mix.
With independent outputs, each destination would need its own picture and sound composition. The sources reviewed for this setup do not establish that a single OBS instance reliably provides that isolation. A discussion or user report about a particular plugin version is not enough to confirm behaviour across current versions, operating systems and configurations.
There is also a third possibility: YouTube’s horizontal and vertical dual-stream feature. It offers two viewing formats for one stream, with a shared URL and live chat. That may suit viewers who prefer different screen formats, but it is not two separately programmed relaxation events. YouTube explains the feature in its dual-format live streaming guidance.
Before setting anything up, write down what must differ between the two destinations. If the answer is “nothing; the same loop should be available at two events”, a multi-destination output may fit. If the answer includes different visuals, audio, schedules or scene changes, treat it as an independent-production requirement and test it separately.
Send the same programme to two events
For two copies of the same programme, the basic workflow is straightforward, although each event still needs its own destination details. Create or schedule two live events in YouTube Studio. For each one, note the stream URL and stream key from its Live Control Room settings. YouTube’s encoder setup instructions describe using those details and checking the preview before going live.
A stream key is sensitive. YouTube describes keys as a stream’s “password and address” in its live stream settings guidance. Keep each key private, enter it only in the intended encoder destination, and reset it if you believe it has been exposed. Do not paste keys into screenshots or public support posts.
In OBS, the Multiple RTMP Outputs plugin is intended to send output to multiple RTMP ingest points. The setup is to add a destination for each event and enter that event’s server and key details. The plugin’s multi-destination capability is supported here by OBS community guidance, rather than by current official plugin documentation, so check the current release information and compatibility before treating it as production-ready. The OBS forum discussion of Multiple RTMP Outputs is useful context, not a guarantee for your setup.
Once configured, start the outputs and check the preview and stream health for each event in YouTube Studio. The encoder feed reaching YouTube is not necessarily the same as the event being publicly live: follow the Live Control Room workflow for each destination and confirm the intended event is live before sharing its link.
If you are operating a long-running relaxation channel, this matters beyond initial setup. A duplicated feed can save you maintaining two encoders or two copies of the same OBS scene, but a restart, network interruption or mistaken key can affect the destinations together. A practical stream-health checklist for playlist restarts is relevant even if your source is not an FFmpeg playlist: monitor what viewers actually receive, not only whether OBS appears to be running.
Check YouTube active-stream limits
YouTube’s current Help page sets limits of up to 10 active streams per channel and up to 3 active streams per stream key. Both limits apply at the same time. These are platform limits, not targets, and they do not mean a particular channel is otherwise configured to run that many destinations. Check YouTube’s current live-streaming help page before relying on the figures, because platform rules can change.
For example, if two events on the same channel are already active, count those against the channel’s active-stream limit. Also check how many active feeds use the same key. If either limit has been reached, adding another output will not make the event start. Do not try to work around a limit by assuming a different OBS configuration changes YouTube’s rules.
Keep the distinction between events, channels and keys clear in your notes. A destination entry in a plugin is not itself a YouTube event, and an event’s key is not interchangeable with another event’s key. Before a broadcast, match each OBS destination to the intended event and verify that you have not reused a key by accident.
A channel owner or manager can manage a stream key through YouTube Studio. If you have a small team, agree who is allowed to create events and reset keys. That reduces the chance of a late change leaving OBS pointed at an old destination. For ongoing operations, an alert plan for a 24/7 stream can help you notice when a feed or event stops behaving as expected, but alerts do not replace checking the Live Control Room.
Install and verify plugin compatibility
Do not start with installation; start by checking the versions involved. The OBS compatibility table lists Multiple RTMP Outputs for Windows, Intel macOS and Apple macOS for OBS Studio 28. That table was published on 31 August 2022, and it does not confirm compatibility with current OBS builds. The OBS Studio 28 plugin compatibility table is useful historical evidence, but it is not a current compatibility promise.
Check the plugin’s current release notes and support information for your operating system and OBS version. If the evidence is unclear, ask in the plugin’s support channel or test on a non-production configuration before changing the computer that runs your scheduled channel. Avoid updating OBS or a plugin immediately before an important broadcast without time to test the complete chain.
After installation, open OBS and confirm that the plugin interface appears and that it accepts the intended destination details. Add the two YouTube destinations separately, label them clearly, and check each server URL and key against its event in Studio. Never infer that a destination is correct simply because a plugin field is filled in.
Also check the upload connection and encoder settings. Each active output consumes capacity according to its bitrate and the way the plugin handles output; there is no universal upload-speed figure that can be safely prescribed for an unspecified connection and configuration. YouTube publishes recommended bitrate ranges by codec, resolution and frame rate in its encoder settings guidance. Choose settings that match your actual format and test them under the conditions in which you plan to broadcast.
If your existing one-output stream is already close to the practical limit of your connection or computer, a second destination may expose the weakness. Watch OBS’s indicators, both YouTube previews and the network behaviour during a sustained test. Do not treat a brief successful connection as proof that an overnight channel will remain stable.
Why independent programmes are different
A multi-output plugin sends the OBS output to multiple ingest destinations. That description supports duplication, not separate programme production. If you change from a candle visual to a forest visual in the OBS preview, the safe assumption is that the programme output itself has changed for all destinations receiving it.
A user report in an OBS forum described both destinations changing when the selected scene changed. That is a warning example, not a definitive description of every plugin build. It does, however, show why a settings screen with two destinations should not be mistaken for proof of independent scene control. The available research does not verify current per-output scene or audio isolation for your particular OBS version, plugin version and operating system.
If you need different audio, verify that the configuration can route separate mixes to separate outputs; if you need different visuals, verify independent scene selection. Then test both at once. Check the actual YouTube previews and playback, because a local preview only tells you what OBS is composing, not necessarily what each destination receives.
For a channel that needs genuinely separate programmes, consider whether separate OBS instances or separate encoding workflows better fit the requirement. Those approaches have their own operational costs: more configuration to maintain, more resource use or more dependence on separate machines or services. The right choice depends on the desired independence and the time you can spend testing and monitoring. The sources reviewed do not establish one universally reliable method for producing two distinct programmes from one OBS instance.
If the goal is simply a dark-screen ambience feed, rather than two independent channels, you may be able to simplify the programme itself. This guide to a 24/7 white-noise stream with a dark screen covers a single-programme use case and can help you decide whether you need a second output at all.
Test before relying on the setup
Test with the exact operating system, OBS build, plugin build, encoder settings and network connection you intend to use. Create private or unlisted events if that is appropriate for your workflow, and confirm what the current YouTube controls allow. The purpose is to find configuration mistakes without treating an untested public broadcast as a rehearsal.
First, verify each event independently: correct title and visibility, correct stream URL and key, and a preview appearing in the intended Live Control Room. Then run both outputs together. Watch both previews for picture and sound, check for a delay or dropped output, and confirm that changes to OBS scenes behave as expected at both destinations. If the programme should be identical, confirm that the same scene and audio reach both. If they should differ, do not proceed until the distinction has been demonstrated at the destinations themselves.
Test the settings for long enough to observe the sort of operation you expect, rather than stopping as soon as both previews appear. A relaxation stream may have quiet audio, a long static shot, or a slow visual change; check that those elements remain present and do not rely only on movement to spot a frozen feed. Note the time, settings and any warning messages so that you can reproduce a problem.
Finally, rehearse recovery. Stop and restart an output in a controlled test, confirm how the event behaves, and make sure you know which controls in OBS and YouTube Studio need attention. If the channel must continue while your home computer is off, that is a separate operating model from an OBS instance running on that computer. StreamNeo addresses that particular computer-running burden by taking an uploaded file and running it as a YouTube live stream, but it is YouTube-only and does not establish that you can create two independent programmes from one OBS setup.

FAQ
Can one OBS setup send the same relaxation video to two YouTube events?
Yes, the Multiple RTMP Outputs plugin can be used to send the same OBS programme to multiple RTMP destinations. Configure the URL and stream key for each event, verify compatibility with your current software, and check both events in YouTube Studio.
Can each event show different scenes or music?
Do not assume so. The sources reviewed support sending one programme to multiple destinations, but do not establish reliable independent scene or audio outputs from a single OBS instance. Test your exact versions and verify picture and sound at both destinations before planning a broadcast around it.
Does YouTube’s horizontal and vertical option create two separate relaxation streams?
No. It provides horizontal and vertical viewing formats for one stream, with a shared URL and chat. It is not evidence that you can programme separate audio, scenes or events for two audiences.
What should I check if a second output will not start?
Check that each destination has the correct event’s stream URL and key, that your plugin is compatible with your OBS version, and that you are within YouTube’s active-stream limits. Then check the OBS output status, YouTube Studio preview and available connection capacity; avoid changing multiple settings at once so you can identify the cause.
