A computer-based encoder cannot keep sending video to YouTube after the computer running it shuts down. To keep a broadcast going with that computer off, both the source and the encoder must continue on another powered device or service.
“Astra Streaming” can refer to different products. The Astra Streaming Studio listing describes streaming from an Android device and support for RTMP; it does not document taking over an existing computer feed. So the answer for a desktop encoder is no, and any alternative needs to be matched to what your video source actually is.
Short answer: shutdown stops a computer-hosted encoder
An encoder turns a video source into a stream YouTube can receive. If your encoder is an application running on your computer, that application depends on the computer being powered and operating. When the computer shuts down, it stops sending its feed. YouTube cannot continue receiving new video from an encoder that is no longer transmitting.
That does not necessarily mean every part of a YouTube broadcast behaves identically at the instant your computer goes off. The relevant point is simpler: no new content can arrive from the stopped encoder. YouTube’s own encoder guidance says to end a stream by stopping the content sent from the encoder. The broadcast’s state and what viewers see can depend on the stream setup, so check YouTube’s current guidance and test your own channel rather than assuming the image will freeze, end, or recover in a particular way.
If you mean “Can I turn off my computer and keep YouTube Live running?”, the practical answer depends on whether your video source and encoder can operate independently of that computer. A phone streaming its own camera, a hardware encoder connected to an independent camera, and a hosted service playing a prerecorded file are different arrangements. None should be treated as a handoff from a desktop encoder unless the product documentation explicitly says that is supported.
How YouTube receives an encoder feed
YouTube Live receives video and audio sent by an encoder. YouTube’s setup flow asks you to configure an encoder with the server URL and stream key for your broadcast. The encoder may be software on a computer or a separate hardware device. In either case, it must have a source to encode, power, and a network path to send the feed.
A stream key identifies the broadcast destination for an encoder; it does not create or preserve video by itself. Copying the key to a second device does not automatically make that device reproduce the computer’s screen, game, camera, or playlist. The second device needs its own source and a compatible encoder configuration. Keep the key private, particularly if more than one person has access to your channel. For account access problems, see this guide to YouTube Live streaming access for a channel managed by another account.
YouTube’s official Create a YouTube live stream with an encoder guide explains encoder setup and includes software and hardware examples. Use the current version of that page for account requirements and configuration steps; settings and interface labels can change. The basic mechanics remain useful: YouTube receives what the configured encoder sends, not a copy of a computer that has been switched off.
What Astra Streaming Studio documents
The name “Astra Streaming” is not enough to identify a single product or capability. The Google Play listing for Astra Streaming Studio describes an Android application for mobile streaming and mentions RTMP support. That is evidence of a mobile-streaming app, not evidence that it can keep a desktop encoder operating after shutdown or take over its existing feed.
The distinction matters because RTMP is a way to send a stream to a compatible destination; its presence in an app listing does not establish every part of a YouTube setup. The listing does not, by itself, confirm a particular YouTube configuration, continuous prerecorded playback, or a transition from a desktop feed to a phone. Check the app’s current instructions and test the intended configuration before planning a broadcast around it.
There is also a separate product name, DataStax Astra Streaming, which refers to a data and event-streaming service rather than a YouTube video encoder. The DataStax Astra Streaming FAQ helps distinguish that use of the name. If someone has recommended “Astra” to you, confirm the exact product, platform, source type, and documented workflow before treating it as a solution to a computer shutdown.
The available documentation reviewed here does not establish that Astra Streaming Studio can accept a computer’s current YouTube feed and continue it after that computer turns off. It also does not establish an automatic handoff between a desktop encoder and the app. Do not plan continuity around either assumption. A product may have features beyond a short store listing, but those need to be confirmed in its own current documentation and tested with your channel.
Separate the video source from the encoder
A common source of confusion is treating the video and the encoder as one thing. The source is what you want viewers to see: a desktop capture, a webcam, a camera, a collection of recorded bhajans, or an ambient loop. The encoder captures or reads that source, prepares the video and audio, and sends the resulting feed to YouTube.
For a computer screen capture, both parts may be on the same machine. Your computer generates the screen image and runs the encoder. Switch it off and the computer-generated source disappears along with the encoder. Moving only the encoder to a hardware device or hosted service cannot restore a game, browser window, or desktop capture that no longer exists.
A camera connected to an independent hardware encoder is different. If the camera, encoder, network, and power remain available, the computer can be off while that separate arrangement sends video. That is not the computer feed continuing; it is a different source and encoder doing the work. You need to configure the destination and verify the source before relying on it.
Prerecorded content has another path. A service or device that can read a file and send it continuously may work without your computer, provided the file is available to it and the product supports the format, schedule, and controls you need. A playlist of recorded devotional music, for example, is not the same technical problem as transmitting a live desktop. For planning a recorded programme, this guide to a nonstop YouTube stream of recorded gospel choir performances may help you think through the source side.
Before choosing equipment or a service, write down the source in one sentence: “the video is a camera in the prayer room”, “the video is my computer screen”, or “the video is a set of recorded talks”. Then identify what reads that source and sends it to YouTube. If both answers point to the computer you intend to turn off, the stream will lose its feed.
Options when the computer must be off
Your options depend on whether the programme is live or prerecorded and whether its source exists independently of the computer. The table is a starting point, not a guarantee that a specific setup works with your account or content.
| Source and requirement | Possible approach | What must remain available | Main limitation |
|---|---|---|---|
| Desktop capture or gameplay that exists only on the PC | Keep the PC and encoder running, or recreate the source elsewhere | The computer or a new independent source, encoder, network, and power | A separate encoder cannot capture a PC that is off |
| Live camera or other independent video input | A standalone hardware encoder connected to that source | Camera or input, encoder, network, and power | Requires a compatible source and a separate setup |
| Recorded files to play as a continuous programme | A supported hardware playback feature or hosted video service | The file, service or device, network, and power | Check file support, scheduling, account requirements, controls, and terms |
| A phone’s own live camera | A mobile streaming app configured for the intended destination | Phone, camera, power, network, and compatible app settings | This is a phone-originated stream, not a desktop-feed handoff |
If the source is live and only exists on your PC, the most direct choice is to leave that computer awake with its encoder running, or move the source capture to a device that can remain on independently. A Windows PC set up for playlist streaming, for instance, still needs to be running; this walk-through for running FFmpeg as a 24/7 YouTube playlist streamer on Windows can help you understand that computer-hosted arrangement. It does not make shutdown compatible with continued encoding.
For a live camera feed, YouTube lists standalone encoders, including the AJA HELO Plus. Its documentation also describes a PlayToStream feature for scheduling prerecorded media to YouTube Live without a computer. That is a hardware route to investigate for the appropriate source, not a promise that it can inherit a desktop feed. Review YouTube’s encoder guidance for the device’s documented role and verify current compatibility with the manufacturer before buying.
For recorded files, a hosted service may be more convenient if you do not want to maintain a computer. YouTube’s encoder guide points to cloud streaming products for continuous prerecorded streams. Check the provider’s own current documentation for supported file formats, channel setup, account requirements, runtime limits, stream controls, support arrangements, and terms. Do not infer that Astra offers this cloud-video function from the name or from the Android app listing.
A mobile app is relevant only when the phone itself can supply the intended video and maintain the stream. The Astra Streaming Studio listing mentions RTMP, but you should confirm its current configuration for YouTube and test the phone as the actual source. It does not answer whether an existing PC-originated feed transfers to the phone. If you need recorded material rather than a live phone camera, compare the workflow with this guide to looping Tamil gospel songs and sermons on YouTube Live with FFmpeg.
Check the stream before relying on continuity
Test the complete arrangement, not just the encoder’s settings screen. Configure the source and destination, begin a private or otherwise suitable test where available, and confirm that YouTube receives the expected video and audio. Watch from a second device or browser so you are checking the viewer-facing result rather than only the local preview.
For a planned computer shutdown, test the exact alternative that is supposed to take over, if there is one. Confirm that it has its own source, its own encoder configuration, the correct stream destination, power, and network. If there is no documented handoff, do not treat a test of one device as proof that another will take over. Record what happens when the computer is switched off and on, including whether the intended independent encoder continues sending content and what YouTube shows.
Check recovery as well as the initial start. A brief network interruption, power loss, app closure, or device restart can affect the source or encoder differently. Find out what needs a manual restart and who can do it if you are away. For an overnight devotional channel, a setup that requires you to unlock a phone or reconnect a camera at midnight may not meet the practical requirement, even if it works during a short daytime test.
If the actual problem is that your home computer must be off, but the source is a prerecorded file, a hosted option can remove the need to keep your own computer running; StreamNeo turns an uploaded video into a YouTube live stream that runs with your computer switched off, so it addresses the specific burden of leaving that machine on for prerecorded content. It does not supply a computer-only live source, and it is YouTube-only. Keep the source distinction clear when deciding whether that arrangement matches your channel.

FAQ
Can I turn off my computer and keep YouTube Live running?
Not if the computer is running the only encoder that sends the feed. The stream can continue receiving video only if an independent source and encoder are still operating and configured to send it.
Can Astra Streaming Studio take over my desktop encoder?
The available Astra Streaming Studio listing describes an Android mobile-streaming app with RTMP support, but does not document taking over a desktop feed. Confirm the exact product and its current instructions, then test the intended setup; do not assume a handoff.
Will a hardware encoder keep my PC screen on air?
Not if the screen capture exists only on the PC that is switched off. A hardware encoder may send a separate live input, such as a compatible camera, or support a documented prerecorded playback workflow, but it needs its own source and configuration.
What should I use for prerecorded video?
Consider a service or device explicitly designed to play and send prerecorded content continuously, and check its supported formats, controls, account requirements, and terms. Test the complete YouTube setup before depending on it for an overnight or 24/7 channel.
