Yes, one OBS PC can send two concurrent outputs to separate YouTube live events. For continuous playback, start with OBS’s built-in media sources and playlists; add a multi-output plugin only if you need OBS to send the same or different scene output to multiple destinations.
Treat this as three separate jobs: playing your media, controlling OBS, and creating the YouTube live events. A plugin may help with output destinations, but it does not create or configure every event setting, and it is not required for playlist playback.
Map the jobs before choosing tools
First decide what each stream is meant to show. Perhaps one channel carries a devotional video loop and the other a study ambience feed. They might use separate files and scenes, or the same programme sent to two YouTube channels. Those are different workflows, even though both involve two live outputs.
There are three jobs to plan:
| Job | What it covers | Usually handled by |
|---|---|---|
| Media playback | Playing one video or moving through a playlist | OBS media sources and scenes |
| OBS control | Starting, stopping, switching scenes or restarting playback | OBS controls, scripts or an add-on where needed |
| YouTube event setup | Title, visibility, audience settings, schedule, destination and stream key | YouTube Studio Live Control Room |
Keep these responsibilities distinct. A playlist source can play media without an add-on that controls OBS. A multi-output add-on can send OBS output to more than one RTMP destination, but you still create the events in YouTube Studio and supply each event’s connection details to the encoder.
YouTube’s guidance on streaming across platforms says local hardware or software encoders can support multiple simultaneous streams, while also noting that a limit applies. The page does not give a numeric cap. Check the current guidance and your channel’s access rather than assuming a particular maximum.
Before building anything, write down for each stream: its channel, intended audience, media source, title and visibility, and whether it needs to run on a different schedule. This small inventory will show whether you need two independent OBS compositions or one composition sent to two destinations.
Start with OBS media playback
OBS already has media sources for files and playlists, so a plugin is not a prerequisite for continuous video playback. A single media source can play a file and can be configured to loop. A playlist source can move through multiple files, with playback options that determine what happens at the end of an item or the list. The precise controls can vary with your OBS version, so check the current interface and test the actual files you plan to use.
For one repeating video, create a scene, add a media source, select the file and set the loop behaviour you intend. Confirm that the source is visible in the scene and that the audio meters respond as expected. If you need a slate or a second layout, make those as separate scenes rather than trying to make one media source do several jobs.
For a playlist, add the files in the order you want and test transitions between them. Do not assume that a playlist will continue exactly as you intend after a restart: test what happens if OBS closes during a file, if a file is missing, or if the list ends. Make sure filenames and locations are stable; moving a file after configuring a source can leave OBS unable to find it.
The important distinction is between playback and publishing. OBS can play a playlist locally, but it does not create YouTube events on your behalf. Likewise, YouTube Studio’s scheduling tools do not build the playlist in OBS. If your main problem is rotating material rather than multiple output destinations, a workflow such as rotating playlists on a 24/7 channel is a more relevant planning reference than installing a multi-output tool.
Build a one-video or playlist workflow
For a single file, decide whether both streams should show the same scene or different scenes. If they are the same programme, keep the composition simple: one scene with the media source, graphics and audio you want, then send that OBS output to both destinations. If each stream has different content, create and label separate scenes so you can recognise them during setup and testing.
A practical naming scheme reduces mistakes. Use names such as “Devotional – main” and “Study – main” for scenes, and “Channel A event” and “Channel B event” in your own notes. Names do not change how OBS or YouTube works, but they help you match the correct scene and stream key when several windows are open.
For a playlist, decide whether both channels should play the same sequence. If yes, one scene and one playlist may be sufficient when both destinations receive the same OBS output. If they need different sequences, build and test each sequence separately. Do not assume that two outputs from a multi-output plugin automatically create independent playlists or scenes; the playback choices remain part of your OBS design.
Test the edge of the content, not just the opening seconds. Play through an item change, check the first and last frames, listen for silence or an abrupt cut, and confirm that any on-screen text is legible in the final composition. A devotional loop may need a quiet transition between tracks; a news loop may need its ticker and time-sensitive material reviewed before leaving it running.
If you are still deciding between OBS and a different playback workflow, this guide to streaming a vMix playlist to YouTube Live can help you compare the role of a dedicated playlist setup. It is not a requirement to switch tools; keep the workflow you can test and operate reliably.
Control OBS start and stop
Media playback and output control are separate. You can set a source to loop, but you still need a deliberate way to start the OBS output, stop it, and recover if the PC or network interrupts the session. The right approach depends on whether you are at the computer, managing a scheduled programme, or trying to leave a local PC unattended.
For a supervised test, use OBS’s ordinary controls and check both outputs after starting. Confirm that the correct scene is live, the audio is present and the destinations receive video. When stopping, end each output cleanly and verify the corresponding YouTube event is no longer live. Stopping playback inside a scene is not the same as ending a YouTube broadcast.
If you need automated OBS control beyond ordinary operation, identify the exact action first. Is it starting an output at a set time, switching scenes, or recovering after a disconnect? Consider an add-on or external control only after you know what is missing. A control tool may address an OBS action, but it does not necessarily schedule YouTube events or change their event metadata.
For a local 24/7 run, account for the PC itself: power settings, operating system updates, storage space, OBS alerts and the reliability of the internet connection. Avoid assuming that a machine which works for an evening is ready for a continuous unattended broadcast. If the cost and upkeep of keeping a computer running are the central concern, compare that local approach with the considerations in running a 24/7 YouTube stream on a DigitalOcean Droplet with OBS. That is a separate operating model, not a plugin fix.
Create and schedule each YouTube event
Create an event for each intended live stream in YouTube Studio’s Live Control Room. Check its title, description, visibility, audience and schedule independently. If the streams belong to separate channels, make sure you are working in the right channel before creating each event. The event details and stream key are channel-specific; mixing them up can send a perfectly valid OBS output to the wrong event.
YouTube’s encoder setup instructions explain that you enter the stream details in your encoder. Use the server URL and stream key shown for the relevant event. Keep keys private: anyone with a key may be able to send a signal to that destination. If a key is exposed, use the controls in Live Control Room to replace or reset it, then update the corresponding encoder destination.
If you have not enabled live streaming on a channel before, do this in advance. YouTube says first-time activation can take up to 24 hours. Do not leave activation until the evening you plan to launch. Check eligibility and current channel status on YouTube’s official pages because access can depend on channel circumstances.
Scheduling an event and starting OBS are not interchangeable actions. The scheduled event defines the YouTube destination and its public-facing information; OBS sends the live signal. For each event, note which OBS output will feed it, then check that the correct key is paired with the correct output. Use RTMPS when available: YouTube describes it as RTMP carried over TLS/SSL and recommends it in its streaming protocol guidance.
Add an add-on only for a specific gap
If your workflow needs OBS to send output to two YouTube events at once, a documented path is the Multiple RTMP Outputs plugin. The OBS Project Forums resource page describes concurrent RTMP destinations and offers a choice between sharing OBS’s main encoder and using standalone encoders. This addresses multiple output destinations; it does not replace YouTube Studio’s event setup or OBS’s media playback.
The plugin listing specifies 64-bit Windows and Linux support and an OBS Studio minimum version of 30.2.0. Its resource metadata also shows an old last-update date, so treat those details as a starting point rather than proof of compatibility with your current installation. Check the current plugin resource and release notes before installing, and test it with the exact OBS version and operating system you plan to leave running.
With shared encoding, the plugin can reuse OBS’s main output encoder, which can reduce the additional encoding work. Standalone encoders allow output-specific settings, but require more encoding capacity. There is no general benchmark that can tell you how a particular PC will perform. Test while both streams are active and watch CPU load, dropped frames and stream health rather than inferring capacity from a single-stream test.
For two separate YouTube events, configure each destination with that event’s own server URL and stream key. Check the labels carefully before starting. A plugin configuration does not automatically provide every YouTube event setting: title, privacy, audience and schedule still belong in Live Control Room. Nor does it make a playlist possible; OBS’s built-in playback is enough for that job.
If two local encodes put too much demand on the PC or connection, reconsider the workflow rather than adding more controls. YouTube describes local encoding as offering control and potentially high quality when the computer is capable, and cloud relay as a simpler, lighter-on-PC route, particularly as destination counts rise. Which suits you depends on the actual outputs, network and operating constraints, not a blanket rule.
Check bandwidth and encoding capacity
Two streams may mean two separate outgoing encoded feeds, so plan for the combined upload demand. YouTube’s bandwidth guidance says to allow upload headroom and gives the recommendation “primary + backup + 20%”. For two independent outputs, assess the total configured bitrate and leave room for ordinary network variation; do not treat a speed-test result as a stable guarantee of usable upload capacity.
The settings that matter are not only bitrate. Resolution, frame rate, encoder choice and whether outputs share encoding all affect the work involved. Start with settings that suit the content and the connection, then evaluate the actual stream health for both events. A static devotional image with gentle movement and a fast-changing local news loop may need different quality choices, but neither should be set beyond what the sustained connection can carry.
Check the encoder and network together. If dropped frames appear, distinguish rendering or encoding strain from network drops using OBS’s status indicators and YouTube’s stream health view. Reduce the load or bitrate and retest if necessary. A single good preview does not establish that both outputs will remain healthy under the full workload.
Test the complete workflow before leaving it
Run a full preflight with the intended scenes, media, encoders, keys, connection and both events. YouTube recommends testing with movement and audio, checking the Live Control Room preview and monitoring stream health. Open each event’s preview or watch page, verify its identity, and make sure the picture and sound are the ones you expect.
Use a checklist that follows the workflow rather than only the plugin settings:
- Confirm each event is on the intended channel and has the intended title, visibility and schedule.
- Match each OBS destination to the correct YouTube server URL and key.
- Start both outputs and confirm that both events receive a preview.
- Check audio, motion, scene layout, playlist transitions and stream health on each event.
- Stop and restart in a controlled test, then see whether your media and output behaviour is as expected.
- Record the steps and any recovery action so another person can operate the setup.
For a continuous channel, a short launch test is not evidence of long-run reliability. Leave the complete configuration running for a meaningful period before relying on it, with someone available to observe alerts and intervene. Sources do not establish a guaranteed duration or uptime for this particular setup, so judge it from your own preflight and the failure modes you observe.

FAQ
Can OBS stream to two YouTube channels at once?
Yes, OBS can be configured to send concurrent outputs using a multi-output route such as Multiple RTMP Outputs. Each destination needs the correct event details, and you should test both outputs together. YouTube’s current guidance refers to a limit but does not state its number, so verify current channel access rather than assuming a cap.
Do I need a plugin to play a playlist continuously?
No. OBS has built-in media playback and playlist options, so a plugin for multiple RTMP destinations is not required for playlist playback. Test the item transitions and restart behaviour with your actual files before leaving the stream unattended.
Does the multi-output plugin create my YouTube events?
No. Create and schedule each event in YouTube Studio, then use its destination details in the relevant OBS output. Event titles, visibility, audience settings and schedule are separate from the plugin’s job of sending an encoder output.
Should I use shared or standalone encoders?
Sharing OBS’s main encoder can reduce extra encoding work, while standalone encoders provide more independent output settings and need more capacity. The better choice depends on your PC and configured outputs. Test both destinations under the intended workload and use stream health and OBS status to guide the decision.
