If you want two YouTube radio streams from one OBS computer, first decide whether they need different content or are identical simulcasts. Different feeds usually need separate outputs and event settings; an identical feed may be easier to distribute through a relay, depending on what that service supports.
YouTube accepts concurrent live streams, but the channel-wide and per-key limits both apply. One computer can also become a bottleneck when it has to encode and upload two outputs, so test the complete setup rather than assuming it will hold through a long broadcast.
Decide whether the two feeds differ
Write down what a listener should hear and see on each channel. “The same bhajan programme in two languages”, “the same music with two different visuals”, and “two separate radio schedules” are different production requirements, even if all three are described as two streams.
If both feeds must have different audio, playlists, language, titles or schedules, treat them as two productions. You will need to keep their inputs and event details separate, then verify that the audio and visuals are routed to the intended output. A second event alone does not create a second programme.
If the broadcasts are truly identical, consider whether you need two YouTube watch pages or only a second destination. A relay can take one incoming programme and distribute it, which is conceptually different from producing two independent feeds. Check whether a relay supports the separate YouTube events and controls you need before relying on it. YouTube’s overview of streaming across platforms explains the broad distinction between local and cloud encoding, including that cloud encoding may reduce the work on your computer.
| Method | Often fits | Trade-off to check |
|---|---|---|
| Two OBS instances, each with its own output | Different audio, visuals or event settings | More encoding and upload work; isolate profiles and scenes |
| One OBS feed distributed by a relay | Identical programme sent to more than one destination | Confirm support for the required events, latency and destination controls |
| Multiple-output plugin | A production that needs additional output controls | Verify current compatibility and whether the required independent routing is supported |
There is no universally best option. If you have separate programmes, make that requirement explicit before choosing software. If the content is identical, avoid building two local encodes until you have checked whether distribution of one feed is sufficient. For a single looping programme, the practical choices in FFmpeg versus OBS for playlist streams may also help you think through how the source programme is assembled; it does not remove the need to configure each YouTube destination correctly.
Check channel eligibility and current stream limits
Before configuring OBS, confirm that live streaming is enabled for the channel and that it has no restriction preventing the planned broadcast. YouTube says first-time live activation can take up to 24 hours, so do not leave channel eligibility until the evening you expect to go live. Review YouTube’s current live-streaming eligibility and limits in Studio or Help before setup.
The current Help page states a limit of 10 active streams per channel and 3 active streams per stream key, with both limits applied at the same time. These are platform limits, not a recommended target or a promise that your channel can begin streaming immediately. They can change, so verify them on YouTube’s Help page before planning the broadcasts. Two planned feeds fit below the stated caps only if other active streams and key usage are also taken into account.
Keep the two limits distinct. The channel cap concerns all active streams on that channel. The key cap concerns active streams using a particular stream key. If you reuse a key, its concurrent use matters; if you configure distinct keys for the events, you still need to respect the channel-wide cap. Do not create extra streams as a workaround for an eligibility or restriction issue.
A live event is not the same thing as a stream key. The event is the scheduled or live destination in YouTube Studio; the key and server URL are credentials and connection details used by the encoder to send video to that event. YouTube describes stream keys as similar to a password and address. Treat each one as private, and never put it into a public screenshot, document or chat. The stream settings guide covers key management and related settings.
Create the YouTube broadcast events
Create or schedule two separate live events in YouTube Studio. Give each a recognisable title, description, visibility and schedule. For example, “Morning Bhajans — Hindi” and “Morning Bhajans — Instrumental” tell viewers and the person operating OBS which feed they are looking at. A clear naming scheme also reduces the chance of sending the right programme to the wrong watch page.
For each event, note the event name and the matching server URL and stream key in a private record. If you use separate keys, label them carefully and keep the mapping unambiguous. A useful private checklist has one row per feed, with the event name, key label, OBS profile, audio source and planned start time. Do not copy the secret key into a checklist that will be shared with volunteers or published on a public drive.
YouTube’s encoder setup instructions walk through creating the event, connecting an encoder and using Live Control Room. Follow the current Studio labels; its interface can change. Check visibility and scheduling deliberately. A private test is useful for your own checks, while an unlisted event can help you test the audience-facing watch page with a small group. In either case, confirm which setting you have chosen before the real broadcast.
If this is the channel’s first live session, account for activation time and any verification steps rather than treating them as OBS problems. If a scheduled event does not appear as expected, resolve the Studio or eligibility issue before changing encoder settings. A sound signal in OBS cannot make an unavailable or incorrectly configured YouTube event ready.
Configure a separate output for each feed
For different feeds from one computer, a straightforward local arrangement is to run two OBS instances, with each instance responsible for one YouTube event. OBS forum guidance describes using separate instances for distinct streams and recommends giving each its own profile and scene collection. This is community guidance rather than a guarantee for every operating system or OBS release, so back up your configuration and test the launch method with the version you have installed.
Keep the profile and scene collection for each instance distinct. A profile holds output-related settings, while a scene collection holds scenes and sources. If both instances open and edit the same configuration, changes can collide or leave you unsure which settings are active. Name each set plainly, such as “Hindi radio output” and “Instrumental radio output”, and avoid making simultaneous edits to shared files.
In each instance, set the stream destination using the server URL and key for its corresponding YouTube event. Then check the output mode, encoder and other settings against the requirements shown in YouTube Studio and the capability of your computer. Do not assume that duplicating an OBS window duplicates a correctly mapped stream. Recheck the destination after opening each instance, especially before starting an event.
A multiple-output plugin is another possible route, but a plugin’s compatibility, maintenance and routing behaviour can vary by OBS version and platform. The available research does not verify a particular plugin as current or suitable for independent audio feeds. If you choose one, check its current project documentation and test its exact behaviour before making it part of an unattended broadcast. Two separate instances are easier to reason about when the feeds need distinct production settings, but they also mean more work for the computer.
One OBS output sent to a relay may be simpler for identical simulcasts. It is not a substitute for separate production if each station needs its own audio mix, visuals or schedule. Before using a relay, check whether it supports the specific YouTube destinations and controls you require, and account for its own costs and possible delay. Do not send a single feed through a relay and assume that separate event identities or mixes will appear automatically.
Route audio and visuals correctly
The most common mistake in a two-feed setup is not the key; it is assuming that each output contains the right source. Decide explicitly which audio device, media source, playlist or application belongs in each instance. If one feed is devotional music and the other is a local news loop, make sure a microphone or desktop-audio source intended for one does not leak into the other.
Check each scene collection independently. A still image, logo, text overlay or video loop should match the event title and the actual programme. If you use a browser source or a playlist, test what happens when it ends, reloads or changes track. Each OBS instance may need its own source path and playback behaviour. A familiar OBS scene does not prove that the second instance has loaded the same files correctly.
Listen to the output, not only to the computer’s speakers. Monitoring arrangements can differ from the stream output, and muted or misrouted sources may not be obvious from the preview image. In each instance, check meters while the intended programme is playing, then inspect the audio in YouTube’s preview. If one feed is silent, first check the source and routing in that instance rather than raising every output level.
For a playlist-based station, keep the source media and loop behaviour in view during testing. The OBS and VLC playlist walkthrough is relevant if that is how you build a continuous programme. If your problem is a black picture rather than an audio mix, the checks in this guide to a YouTube stream showing a black screen may help isolate a visual-source issue. Those articles address their respective production problems; you still need to confirm the correct feed in each separate event.
Test both streams and monitor the computer
Run a realistic test before announcing the streams. Start each OBS output and wait for the matching event’s preview in YouTube Live Control Room. Confirm the event title, video, audio and stream identity for both feeds. Open each audience-facing watch page as well, using the intended visibility, so you know what a listener would actually see.
Where practical, use a private or unlisted test event before the public schedule. Start one output, verify its mapping, then start the other and repeat the checks. This sequence helps identify a wrong key, wrong scene or missing audio source without having to diagnose two simultaneous problems. After confirming each one alone, test them together: the combined load is the condition you need to assess.
Two local outputs increase encoding work and upload demand. OBS must composite and encode the feeds, while the connection must upload both. How demanding that is depends on settings such as resolution, frame rate, bitrate and encoder choice, as well as what else the computer is doing. There is no universal CPU, GPU or upload-speed minimum for this exact arrangement. Avoid planning around a specification that has not been tested with your own content and connection.
During the combined test, watch for dropped frames, encoder overload, interrupted audio and a preview that falls behind or disappears. Check the computer’s resource use and leave room for ordinary variation: a browser, file scan or other process can compete for resources. YouTube’s guide to streaming across platforms stresses adequate upload capacity and distinguishes local encoding from cloud encoding. Use a stable connection and test at the settings you expect to keep, rather than using a low-load test configuration and changing it on launch day.
If the computer cannot sustain both feeds reliably, reduce the work in a controlled way and test again, or consider a cloud-based approach for distribution or encoding. That may reduce local computer load, but check that it supports the independent content and event behaviour you need. For a station where leaving the computer running is itself the fragile part of the plan, StreamNeo removes that specific burden by turning an uploaded file into a YouTube live stream that keeps running with your computer off; it is YouTube-only and does not replace the two-output OBS workflow when you need distinct feeds from that computer.
Finally, agree who is allowed to stop each event and how the operator will identify it. YouTube’s encoder guidance notes that streams shorter than 12 hours are automatically archived; check the current instructions for how your event behaves and end each broadcast deliberately when appropriate. Keep a private handover note with the event names and OBS instance labels, not the stream keys. A second person should be able to tell which output is live without guessing.

FAQ
Can one OBS instance send two different radio streams?
The standard OBS stream setup is centred on one output, so two independent feeds require additional configuration, such as separate OBS instances or a suitable multi-output tool. Verify that your chosen method supports separate audio and event destinations, then test it with your installed OBS version. Do not assume a second YouTube event creates a second OBS output.
Can both streams use the same YouTube stream key?
YouTube applies a concurrent-stream cap per key as well as a channel-wide cap. The current Help page lists 3 active streams per key and 10 per channel, but verify the limits before setup because they may change. Keep keys private and map each encoder output to the intended event.
Will one computer handle two 24/7 streams?
It depends on the encoders, settings, programme sources, computer and connection. Two feeds add encoding and upload work, and no universal specification guarantees that a particular computer will cope. Test both together for a meaningful period and monitor quality before relying on the setup overnight.
What if the two broadcasts are identical?
If the content, audio and visuals are identical, compare two local outputs with sending one feed through a relay. Confirm that the relay supports the separate YouTube destinations and watch pages you need. If the feeds are meant to differ, a single relayed feed does not provide independent production by itself.
