You can stream a radio playlist to YouTube Live by using GStreamer to play each track, queue the next item before the current one ends, encode and mux the audio, then send it to YouTube over the ingest URL and stream key shown in Live Control Room. The maintainable approach is an application that manages the playlist and GStreamer pipeline; the exact elements and encoder settings depend on your installed GStreamer plugins and the formats you plan to play.
How the stream fits together
The basic path is: playlist entries go to a GStreamer player, decoded audio is converted and encoded, the encoded stream is placed in an FLV container, and an RTMP sink sends it to YouTube. The documented rtmp2sink accepts FLV input; the plugins and caps needed for playback and encoding depend on your local installation.

For a standard continuous live encoder workflow, use the current RTMP or RTMPS endpoint supplied by YouTube. RTMPS is RTMP transported over TLS/SSL, protecting the connection in transit. Do not copy an ingest URL from an old third-party guide: YouTube provides the current URL and key for your stream in Live Control Room.

Install the components your formats require
Install GStreamer core along with the playback, codec, conversion, muxing and RTMP plugins required for the files and output format you choose. Plugin availability varies by operating system, distribution and GStreamer release. The documented rtmp2sink is part of the Bad Plug-ins package, but that does not mean every installation has it enabled.

Inspect the local installation before building the pipeline:
gst-inspect-1.0 playbin
gst-inspect-1.0 rtmp2sink
gst-inspect-1.0 flvmuxAlso inspect the encoder and audio conversion elements you intend to use. If an inspection reports that an element is unavailable, install the relevant plugin package or choose an encoder present on your system. Confirm the output caps and codec requirements against YouTube’s current ingest guidance before broadcasting.
Use absolute URIs for playlist entries
playbin takes a URI, not a relative file path. For local files, provide an absolute file URI; for network-hosted items, use a valid network URI that the installed source plugins can open. The GStreamer documentation explains the playbin URI property and playback behavior at GStreamer playbin documentation.

Queue tracks to reduce gaps
Use about-to-finish to provide the next URI
In an application, connect to playbin‘s about-to-finish signal and set the next absolute URI before the current item ends. This is GStreamer’s intended queueing mechanism for gapless-style playback. The callback is emitted from a streaming thread, so keep its work small. If the playlist is dynamic, protect access to the queue and hand off more complex playlist operations safely rather than doing lengthy work inside the callback. See the playbin signal documentation and GStreamer’s gapless playback design.
Queueing the next URI early can reduce boundary interruptions, but it does not guarantee silence-free transitions for every format. Buffering time, compressed-format codec delay and frame boundaries can affect the result. Test transitions with the actual files you plan to use.
Understand the simpler end-of-stream approach
An application can wait for end-of-stream (EOS) and then start playbin again with the next item. This is simpler, but it can introduce a gap at each track boundary. If you use this method, keep the RTMP output in the required state across track changes; stopping and rebuilding the entire output may interrupt the broadcast.

- PLUG IN AND HEAR SOUND IN SECONDS - USB Type-A connector with a 3.5mm stereo headphone output and a separate 3.5mm mono microphone input. No drivers, no software, no external power - the adapter is USB bus-powered and is recognized as a standard USB audio device.
- WORKS ON WINDOWS, MAC AND LINUX - Driverless on Windows 98SE/ME/2000/XP/Server 2003/Vista/7/8, Linux and Mac OSX, and compliant with the USB Audio Device Class 1.0 specification, so any system that supports class-compliant USB audio will see it. Select it as the sound output and input device after plugging it in.

Build and start the output pipeline
Choose a compatible chain
Construct the graph for the media formats, encoder and caps available on your machine. A typical audio path is playback and decoding, audio conversion, encoding, FLV muxing, then rtmp2sink. GStreamer’s documented RTMP2 output example connects an FLV muxer to rtmp2sink; consult the rtmp2sink documentation for the element’s properties and example.
Recommended Free Tools
There is no single static gst-launch command established here as tested across installations. Element names, encoder availability, caps and URI handling vary. Build and validate the pipeline against your local plugin inspection results instead of assuming a command from another system will work unchanged.
Get the current YouTube ingest details
- Open YouTube Studio and go to Live Control Room. Create or select the scheduled or live stream you intend to use.
- Copy the ingest URL and stream key shown for that stream. YouTube’s live resource describes ingest type and primary and backup ingest URLs as delivery configuration; see the YouTube LiveStreams resource.
- Provide the URL and key to the GStreamer output at runtime using the sink configuration supported by your installed version. Do not publish a real key in code, logs, screenshots or examples. Treat it as a credential and restrict access to its configuration.
- Start the GStreamer application and check both its bus messages and YouTube’s stream health indicators before sharing the broadcast.
Use the secure RTMPS URL supplied by YouTube when available for your setup. Do not substitute an endpoint found in an old guide: the current Live Control Room details are authoritative for the selected stream.

Choose RTMP/RTMPS or HLS
| Ingest choice | When it fits | Practical considerations |
|---|---|---|
| RTMP/RTMPS | A standard continuous live encoder workflow. | Send a continuous stream using the current Live Control Room URL and key. RTMPS encrypts the connection in transit. See YouTube’s live encoder settings. |
| HLS | You specifically need YouTube’s HLS ingestion or a supported codec or feature that calls for it. | YouTube specifies TS segments 1–4 seconds long, a rolling playlist with no more than five outstanding segments, HTTPS POST/PUT and no byte ranges. HLS has higher latency than RTMP. The developer guide also defines M2TS and codec constraints. See YouTube HLS ingestion guidance and YouTube HLS ingestion developer guide. |
For the playlist workflow described here, RTMP/RTMPS is the straightforward route unless a specific HLS requirement changes the choice.

Check both GStreamer and YouTube
- GStreamer bus errors or state changes: handle bus messages in the application; these report playback and pipeline errors or transitions. A source error, missing plugin, caps negotiation problem or output connection failure can prevent a healthy stream.
- YouTube stream health: check Live Control Room after connecting. A running local pipeline does not by itself prove YouTube is receiving a valid stream.
- Viewer-side playback: check the published or preview playback path from a viewer perspective, including audio and track transitions.
- Track boundary silence: if a gap appears, confirm that the next URI is being set early in
about-to-finish, that the callback is not blocked, and that the formats transition acceptably. Try the actual files in sequence.
No end-to-end pipeline or broadcast test is established for these instructions. Validate your plugin set, encoder caps, ingest configuration and viewer playback on your own system with authorized material before relying on the stream.
Clear music rights before broadcasting
A technically successful pipeline does not establish permission to stream the music. YouTube scans live streams for third-party content, and a track described as “free” or purchased elsewhere is not automatically cleared for YouTube Live. Confirm that the license covers the actual live-stream use. YouTube explains that copyright-safe music must be public domain or used with permission, and advises creators to check the actual license in its copyright-safe music guidance.
