Google Cloud Live Stream API accepts SRT as an input protocol. YouTube’s documented third-party ingest protocols do not include SRT, so the practical route is to send an SRT contribution feed to Google Cloud and then distribute the output to YouTube over a protocol YouTube supports, such as RTMP or RTMPS.
That distinction is about where each protocol is used. SRT gets your source feed to the cloud service; a separate downstream connection gets the resulting stream to YouTube. Check compatibility at both ends before building around a particular encoder, endpoint or stream key.
What SRT input means in a cloud workflow
SRT, or Secure Reliable Transport, is a protocol for moving a live contribution feed from an encoder or production system to a receiving service. In this workflow, “SRT input” means the cloud service receives the feed over SRT. It does not mean that every destination the service can reach also accepts SRT.
Think of the workflow as two connections. First, an SRT-capable source sends video and audio to Google Cloud Live Stream API. The cloud service processes the incoming feed and can make output available in formats including HLS and DASH, or distribute it to a remote endpoint using supported options such as RTMP. Second, that downstream endpoint connects to YouTube using an ingest protocol available for the chosen YouTube stream.
The source encoder must support SRT and be configured for the cloud input endpoint. If the source only offers RTMP, it cannot originate an SRT contribution feed without a suitable protocol-capable encoder or intermediary. Google Cloud’s Live Stream API overview describes its supported inputs and outputs; its best-practices documentation recommends SRT over RTMP for its input endpoint when possible.
This architecture is relevant when your production system can send SRT and you need a cloud service to receive or process that feed before it reaches YouTube. It is not automatically simpler than sending a supported protocol directly to YouTube. Each additional hop brings configuration, monitoring and latency considerations.
Does YouTube accept SRT ingest?
YouTube’s documented third-party ingestion protocols are RTMP, RTMPS, HLS and DASH. SRT is not on that list, so do not treat an SRT-capable source as evidence that YouTube will accept a direct SRT connection. Google’s protocol comparison for YouTube Live sets out the documented options.
A source-to-cloud connection and a cloud-to-YouTube connection are different protocol boundaries. You can send SRT into a service that accepts it, but the service must then deliver to YouTube using a protocol supported at YouTube’s receiving endpoint. The word “SRT” on a service’s input feature list says nothing by itself about its output options.
For a typical low-latency YouTube live stream, YouTube recommends RTMPS. HLS can be appropriate for cases such as HDR or codecs that RTMP does not support, but it sends video in segments and therefore tends to have higher latency. DASH is also a documented third-party option; confirm that the specific service and stream configuration support the route you need rather than assuming all protocols are interchangeable.
The key answer to “Can I stream SRT to YouTube?” is therefore: not directly using YouTube’s documented ingest protocols. “Can I send SRT to YouTube through Google Cloud?” is a different question: Google Cloud accepts SRT input and documents remote distribution, including RTMP, which can form the second hop to YouTube. Verify the current endpoint and stream-key choices during setup.
Google Cloud Live Stream API: input and output are separate
Google Cloud Live Stream API accepts SRT and RTMP input. Its overview describes transcoding to HLS or DASH output, with output streams saved to Cloud Storage. Separately, the service documents remote distribution to endpoints using SRT or RTMP. These are related capabilities, but not a single end-to-end promise that any input protocol can be passed unchanged to any destination.
For the YouTube route, the useful documented intersection is an SRT input and RTMP remote distribution. Google’s remote distribution guide specifies MPEG-TS for SRT distribution and FLV for RTMP distribution. YouTube’s accepted ingest list includes RTMP and RTMPS. That makes RTMP a documented protocol match for the second hop, subject to configuring the remote destination and YouTube stream correctly.
Do not confuse an HLS or DASH output created for playback or storage with the remote distribution configuration. A manifest or stored output is not itself proof that the service is pushing a compatible live ingest to your YouTube event. Decide whether you need transcoding, file or manifest outputs, or a remote push, and check the relevant feature documentation for that exact path.
There is also a trade-off in using the cloud as a relay. It can let an SRT-capable production source reach a service that handles the downstream distribution. In return, you must configure and observe two links instead of one, and end-to-end delay may be greater than a direct route. If your encoder already sends RTMPS reliably to YouTube and you do not need cloud-side processing or distribution, the extra SRT hop may not solve a problem you have.
Send the contribution feed to Google Cloud over SRT
Start with the source, not with the destination. Confirm that the encoder or contribution system can send SRT, and check what connection details the selected Google Cloud input endpoint requires. Google Cloud’s guidance discusses SRT input and recommends it over RTMP for that endpoint when possible, citing recovery from packet drops, forward error correction, multiple audio elementary streams and higher bandwidth. Those advantages matter at the contribution hop; they do not change YouTube’s ingest protocol list.
The encoder must support the selected SRT mode and be able to produce a compatible stream. Confirm video and audio settings, the endpoint’s connection requirements and whether your source can maintain the feed. A protocol label alone does not establish codec compatibility or prove that a particular profile will work across the whole chain. Test the actual programme feed, including sound, before relying on it for a long broadcast.
If you are planning a continuous channel, also consider what happens when the source encoder, network connection or cloud input is interrupted. A protocol can help with packet loss, but it does not remove the need to monitor the programme and recover from failures. Readers comparing local and remote approaches may find it useful to review how to run a 24/7 YouTube stream without using your own internet, particularly when the home connection is not intended to carry the broadcast all day.
Keep the boundary visible in your operating notes: source encoder to Google Cloud is SRT; Google Cloud to YouTube is a separate configured output. That simple distinction helps when diagnosing a black screen, missing audio or a disconnected event. If the first hop is healthy but YouTube shows no incoming signal, inspect the remote distribution settings and the destination ingest details rather than changing the SRT source blindly.
Distribute the output to YouTube using a supported endpoint
For the second hop, configure remote distribution from Google Cloud to the YouTube ingest endpoint using a protocol YouTube documents. RTMP is the clearest overlap in the documented workflow: Google Cloud supports RTMP remote distribution, and YouTube lists RTMP and RTMPS among its third-party protocols. Use the actual endpoint and stream key presented by YouTube for the event, and follow the current instructions for that event’s ingest option.
YouTube recommends RTMPS for ordinary low-latency streams. Check whether the remote distribution setup can use the specific secure option and connection details required by the YouTube endpoint you select. Do not assume that a service’s generic RTMP support means it accepts every variant or security configuration without further setup. The selected output format must match both the remote-distribution feature and YouTube’s endpoint.
HLS may be worth evaluating when your delivery has an HDR or codec requirement that RTMP cannot meet, but YouTube notes that segmented delivery tends to add latency. It is not a universal upgrade, and the cloud service must support the required output and destination path. If prompt interaction matters—for example, a live presenter responding to messages—measure the delay in a test rather than choosing by protocol name alone.
For a 24/7 channel, test the entire chain over a representative period before replacing a working setup. Check that the picture and audio are present at YouTube, that the expected event is receiving the feed and that recovery behaviour is understood if either hop fails. A backup YouTube ingest server plan can help you think through destination-side resilience, but it is a separate concern from accepting SRT at the contribution input.
If your actual need is simply to loop an existing video file without keeping a computer on, a live SRT contribution chain may be unnecessary. StreamNeo is designed to take an uploaded video and keep its YouTube broadcast running without leaving your own computer switched on, which addresses the specific burden of maintaining a local playback machine rather than the problem of receiving an external SRT production feed.
Check protocol support before choosing a service
Compare the workflow by hop, not by a single headline feature. Ask what the source can send, what the cloud service accepts, how it processes or transcodes the feed, and what it can push to the destination. Then consider latency, codecs, audio layout, monitoring and failure recovery. The table summarises the questions to verify; it does not imply that every configuration is available for every account or event.
| Part of the workflow | Protocol question | What to verify |
|---|---|---|
| Contribution source to cloud | Can the encoder send SRT? | Confirm the encoder supports the selected SRT connection and the cloud input endpoint’s current requirements. |
| Cloud input | Does the service accept SRT? | Google Cloud Live Stream API documents SRT input; check current endpoint configuration. |
| Cloud processing | Is transcoding or another output needed? | Confirm the desired output format and whether processing changes codecs, audio or latency. |
| Cloud to YouTube | Can the service distribute by a YouTube-supported protocol? | Google Cloud documents RTMP remote distribution; YouTube lists RTMP and RTMPS among its options. |
| YouTube event | Does the chosen endpoint match the output? | Use the ingest option and stream key available for the specific event, and consult current official guidance. |
A direct YouTube workflow can be simpler if your encoder already supports a YouTube ingest option and there is no need for the cloud contribution stage. The cloud relay route can fit a production where SRT is the available contribution protocol or where a cloud processing and distribution step is required. Neither is universally better; the right choice depends on the source equipment, the destination requirements and how much extra operational complexity you can support.
For a small channel run from a home computer, also distinguish protocol compatibility from playback strategy. An encoder-based workflow may be appropriate for a live camera or a remotely produced show, while a pre-recorded loop may be easier to manage another way. The guide to software for looping prerecorded videos on YouTube Live covers that different use case. If you are already using OBS, review how to prevent OBS from stopping a 24/7 sleep-sounds stream after an update for the local-computer reliability side of the decision.

FAQ
Which cloud YouTube streaming service supports SRT input?
Google Cloud Live Stream API documents SRT input. For a YouTube destination, configure a separate output hop using a protocol supported by YouTube, such as RTMP, and confirm the current settings for both services.
Can I send an SRT feed directly to YouTube?
YouTube’s documented third-party ingest protocols are RTMP, RTMPS, HLS and DASH; SRT is not listed. An SRT feed therefore needs a receiving service or workflow that can deliver onward using a supported YouTube protocol.
Can Google Cloud receive SRT and send the stream to YouTube?
Google Cloud documents SRT input and RTMP remote distribution, while YouTube lists RTMP-family ingest options. This supports a two-hop design, but you must configure and test the actual endpoint, output and stream event rather than assume the connection is automatic.
Should I use RTMPS, HLS or DASH for the YouTube output?
YouTube recommends RTMPS for typical low-latency live streaming. HLS can suit certain HDR or codec needs but tends to add delay because delivery is segmented; check YouTube’s current documentation and the cloud service’s supported output path before choosing.
