An AAC internet radio URL gives you audio, not a complete YouTube Live broadcast. To send it to YouTube, an encoder must receive that audio, pair it with a video source such as a station image, and transmit the combined signal to the ingest destination for your channel.
You can assemble that path in OBS Studio or with FFmpeg. The right choice depends on whether you want to operate a graphical desktop setup or automate a simpler relay; either way, confirm the source works, keep the stream key private, and test the output before treating it as ready for a long run.
Check that your channel can go live
Before configuring an encoder, open YouTube Studio and confirm that live streaming is available for the channel you plan to use. YouTube’s current eligibility and activation requirements can change, so check the official live streaming help page rather than relying on an old checklist or another channel’s experience. If Studio says that live streaming is not available yet, resolve that there first; the encoder cannot activate the feature for you.
Once the channel is eligible, decide whether you will create the broadcast in Live Control Room or use an existing scheduled broadcast. A broadcast is the viewer-facing destination: it has its own title, visibility, description and start details. The incoming feed is separate. In YouTube’s API vocabulary, a liveBroadcast represents the broadcast and a liveStream represents the signal sent to YouTube. You do not need to use the API to set up a normal stream, but the distinction helps explain why an audio URL alone cannot create a live page or send a signal.
Set the title, description, audience and visibility deliberately. A private or unlisted test can help you check the picture and sound before a public launch, subject to the controls available for your channel. If you are preparing a devotional station, for example, confirm the broadcast is associated with the intended channel and that its description reflects what the feed actually contains. Do not treat a successful encoder connection as confirmation that every broadcast detail is correct.
There is also a content-rights decision to make before you relay a station. Permission to listen to a radio stream does not automatically establish permission to retransmit it on YouTube. Confirm that you have the rights or authorisation needed for the audio and any visual material, and consult current YouTube guidance for policy questions. No encoder setting resolves rights or guarantees approval.
Prepare the AAC radio URL
Find the exact stream URL from the radio station or provider. It may be an address that ends in a particular extension, but the appearance of a URL does not prove that it is a directly playable AAC feed. Providers can use different delivery methods, redirects, access controls or request requirements. The source in this workflow is whatever the encoder can actually open and decode, not merely a web page where a listener can press Play.
Test the URL from the same machine or environment where the encoder will run. Check that playback starts, continues beyond the first few seconds, and produces the expected programme. If it requires a username, password, token or special headers, obtain the correct access details from the provider and configure them only in a place that will not expose them publicly. Avoid pasting a credential-bearing URL into a public chat, screenshot or stream description.
An encoder’s support for a particular input depends on its build and the stream’s actual transport and container. If OBS or FFmpeg cannot open the address, first ask the station provider for the direct stream URL and any access requirements. Then confirm the encoder can handle that stream type. Do not assume that every AAC feed can be opened in the same way, and do not describe an untested station address as verified.
Keep the incoming source and outgoing YouTube settings distinct. The feed may already be encoded as AAC, but the encoder still has to send an audio stream in a format YouTube accepts for the selected protocol. Its outgoing audio bitrate is not automatically set by the source feed’s bitrate. For RTMP or RTMPS, YouTube’s encoder settings guidance lists AAC or MP3 audio and recommends 44.1 kHz and 128 kbps for stereo as a baseline. Treat that as an outgoing encode target to check against your actual channel and encoder configuration, not as a claim about the provider’s source.
If you are also planning a music station rather than just relaying an existing radio service, the guide to creating a 24/7 Hindi music radio stream covers a broader channel workflow. Here the narrower task is getting one audio source into a properly formed audiovisual live feed.
Add a visual to the audio source
YouTube Live expects an encoder feed with video as well as audio. A radio stream supplies the latter, so add a visual source: for example, a station logo and programme information on a still image, a looped video for which you have permission, or a restrained visualiser. The picture can be simple, but it must be a real video signal from the encoder rather than an assumption that YouTube will turn audio into a broadcast image.
For a still image, prepare a clean graphic at a sensible landscape aspect ratio, with text that remains readable on a phone. Include only information that is useful while listening, such as the station name or current programme, and avoid small scrolling details that are hard to read. A looped visual can add movement, but check that it does not distract from the listening experience or imply that the picture is live when it is not.
Use artwork, footage and other elements you are entitled to use. That includes logos and background clips, not only the radio audio. A static station graphic may be easier to maintain than a video loop, but it still needs to be configured as an active video source in the encoder. For a deeper look at scene contents and on-screen presentation, the guide to 24/7 stream thumbnails discusses the visual expectations around always-live content; a thumbnail is distinct from the live video signal itself.
Check the visual at the intended output size. Look for cropped edges, a blank canvas, unreadable text, or an image that disappears when a media source ends. If the source is a loop, test that it repeats in the encoder rather than stopping after one pass. If it is a still image, verify it remains present continuously while the audio plays.
Combine audio and video in OBS or FFmpeg
OBS Studio is a practical starting point when you want a graphical interface, visible scenes and manual control. Create a scene, add the still image or loop as a video source, and add the radio feed as an audio input that OBS can open. Watch the audio meter while the programme is playing, then confirm the preview shows the intended visual. Source names and available input options can vary by operating system and OBS setup, so verify the exact AAC URL and stream type in your installation.
Before connecting to YouTube, listen to the encoder output locally if your workflow allows it. Confirm that the feed is not silent, that it is not clipping, and that the image is present. If the audio source ends or reconnects, observe what the scene does. A clean preview at the start does not establish that a long-running input will stay available.
FFmpeg can suit a simpler automated path where a stream input is combined with a still image or looped video and encoded as an audiovisual output. Its command-line options depend on the actual source transport, any required authentication, and the installed build. Use the FFmpeg documentation and test with the actual feed rather than copying a command that assumes a different stream format. A process supervisor can restart an exited process, but it cannot make an unavailable station URL, failed network or rejected key work again by itself.
Choose based on how you will operate the relay. OBS is often easier when an operator wants to see a scene and make changes; FFmpeg can be more suitable when the pipeline is simple and needs automation. For an unattended channel, a computer running OBS still has to remain on and connected. A PC-to-VPS migration guide may help you think through where a continuously operated encoder should run, but it does not remove the need to monitor the source and destination.
| Need | Sensible starting point | What to verify |
|---|---|---|
| A manually operated setup with a graphical interface | OBS Studio | The chosen input can open the exact feed, and the scene keeps its image visible. |
| A simple image-plus-audio pipeline | FFmpeg | The installed build can read the source and the output settings match YouTube’s current guidance. |
| Custom scenes, overlays or operator changes | OBS Studio | Every visual element remains visible and the audio source behaves as expected. |
| An unattended relay process | FFmpeg with process supervision, or a managed workflow | Restarts address process exits only; they do not repair a source, network or YouTube problem. |
Whichever route you choose, configure the outgoing video and audio intentionally. YouTube’s guidance includes H.264, H.265/HEVC or AV1 video, constant bitrate and a two-second keyframe interval, with no more than four seconds between keyframes. The recommended video bitrate varies by codec, resolution and frame rate; use its current table and your upload capacity instead of guessing. For a mostly static radio visual, a modest, stable video setting may be adequate, but it must still produce a supported, continuous video signal. The live-stream quality settings guide gives further context on testing and adjusting output quality.
Set up the YouTube Live destination
In YouTube Studio, create or select the broadcast you intend to use. Open its stream settings in Live Control Room and retrieve the ingest URL and stream key associated with that destination. The exact interface can change, so follow the current controls shown by YouTube. If you schedule a broadcast, check that the encoder is paired with that scheduled destination rather than an unrelated stream configuration.
The ingest URL tells the encoder where to send data; the stream key associates the incoming signal with the intended channel stream. Both are operationally important, and the key is a credential. Copy the exact values from the current destination rather than reusing a value from an old tutorial, another channel, or a command example. If you rotate or reset a key, update the encoder configuration that uses it.
The YouTube API documentation describes a liveStream as the feed sent to YouTube and a liveBroadcast as the event viewers watch. Its Live Streaming API resource guide also documents health status and configuration information for API workflows. Most readers can use Studio rather than the API, but this model is useful when diagnosing a case where the broadcast exists yet the encoder feed is missing or unhealthy.
Before going live publicly, review the destination title, visibility, audience selection and any scheduled start details. The channel’s destination and the encoder’s output are two parts of one setup: the broadcast page can be correct while the encoder is pointed at the wrong key, or the encoder can connect while the intended broadcast is not ready for viewers.
Protect the stream key and choose RTMPS
Treat the stream key as a secret. Do not include it in a tutorial screenshot, public issue, shared configuration file or message to someone who does not need it. Be careful when screen-sharing the encoder settings, and avoid leaving a credential in a command history or log that other users can read. If you believe it has been exposed, use YouTube Studio’s controls to replace or reset it, then update the encoder with the new value.
YouTube recommends RTMPS, an encrypted version of RTMP, for encoder connections. For a normal radio relay, use the exact RTMPS ingest URL supplied for the stream when YouTube offers it. The RTMPS ingestion guide describes the protocol requirements, including a valid endpoint and path, TLS on port 443, and correct host-name handling for TLS/SNI. Do not build an endpoint by guessing at a URL copied from an example; use the destination’s current value.
YouTube also documents RTMP, HLS and DASH as ingestion choices. RTMP is unencrypted, while RTMPS is encrypted; HLS and DASH can have different codec options and typically higher latency because they send segments. Those alternatives are not automatically better for a straightforward radio feed. Unless you have a specific delivery or codec reason to use another documented protocol, RTMPS is the uncomplicated default to test.
A connection error can result from an incorrect endpoint, a port or TLS mismatch, or a key that no longer matches the destination. If you see an SSL or timeout error, check the exact protocol and URL first, then confirm that your encoder handles the expected TLS connection. A stream key is not harmless simply because it is not visible to viewers: someone with access to it may be able to send a signal to that destination.
Test and monitor the relay
Run a preflight with representative audio and video before you announce the channel or leave it unattended. Confirm the encoder connects, the broadcast preview receives both picture and sound, and the audio is the intended radio programme rather than a local monitor or unrelated device. YouTube recommends testing with representative content and monitoring stream health; use the health messages in Live Control Room as well as what you can observe in the encoder.
Check the output from a viewer’s perspective too. Open the broadcast on a separate device or browser session, if your visibility settings permit it, and listen for silence, dropouts, distortion and unexpected source changes. Inspect the visual for blank frames or a stopped loop. A preview in the encoder proves only that its scene is composed; the YouTube preview confirms more of the route from encoder to destination.
When a warning appears, narrow the fault by signal path. If there is no video or signal, verify that the image or loop is active and that the encoder is actually sending video. If there is no audio, confirm the source URL is reachable from the encoder host, check any access details, and verify that the selected input can decode the actual feed. Where available, YouTube health reporting may show issues such as noAudioStream, an audio codec problem or a sample-rate warning; use those clues alongside the encoder’s own meters.
For an audio-format warning, check the outgoing encode rather than assuming the source feed’s AAC setting is the whole configuration. For RTMP/RTMPS stereo, YouTube’s guidance gives 44.1 kHz and 128 kbps as a recommended baseline, with AAC or MP3 accepted. If the connection is unstable, test upload capacity and lower the output resolution or bitrate to a setting the connection can sustain. A stable lower setting is more useful than a higher setting that repeatedly fails, but confirm the resulting picture and sound remain acceptable.
Long-running operation adds failure points that a short test does not expose. The station can change its URL, authentication can expire, the encoder host can lose connectivity, or YouTube can report an ingest problem. A restart policy can relaunch an exited FFmpeg process, but it does not guarantee an uninterrupted relay and should not be mistaken for monitoring. Decide who will receive alerts, how they will check the broadcast, and what they will do if the source or destination needs attention.
If the main burden is keeping a local computer powered, the repeated setup and recovery work can become the operational problem rather than the audio format itself. StreamNeo can remove that particular need to leave your own computer running by taking an uploaded video and running a YouTube broadcast from it; that is a different workflow from relaying a live AAC radio URL, so choose it only if an uploaded video fits the programme you intend to publish.

FAQ
Can I send an AAC radio URL directly to YouTube Live?
No. The URL is an audio source, not a complete live broadcast. An encoder must receive that feed, add a video source and send a supported audiovisual stream to YouTube’s destination.
Does the source AAC bitrate become the YouTube audio bitrate?
Not necessarily. The encoder’s outgoing audio settings are separate from the radio provider’s incoming feed, so check the output format and bitrate in your encoder. YouTube’s guidance lists AAC or MP3 for RTMP/RTMPS and recommends 44.1 kHz and 128 kbps for stereo.
Should I use OBS or FFmpeg for a radio relay?
Use OBS if a graphical scene and operator control suit your workflow; FFmpeg can suit a simpler automated image-and-audio pipeline. In either case, first verify that the exact radio URL and stream type are supported by your installation, then test the outgoing signal.
What should I do if the relay stops?
Check the source feed, encoder status, network connection, destination URL and current stream key in that order. A process restart can recover an exited encoder process, but it cannot fix a source outage, bad credentials or a YouTube ingest issue; use the available health indicators to identify what needs attention.
