OBS can start streaming when it launches with the --startstreaming parameter, but that does not by itself restart a computer after an outage or restore every part of a broadcast. This guide uses Windows and YouTube as researched examples; check the current instructions for your own operating system and streaming platform before relying on the same steps.
For a children’s channel, test the whole recovery chain while someone can supervise it: power returns, the computer boots, the network is ready, OBS opens with the right profile, and YouTube accepts the encoder feed and starts the intended event. A running OBS window is not proof that the public stream is live.
Automatic resume is a chain, not a switch
A power outage can interrupt several different things. The computer may be off; its operating system may not be configured to start after power returns; the router may still be rebooting; OBS may not open; a camera or other source may not reconnect; and the platform may not yet be accepting or publishing the encoder feed. Each is a separate point to check.
OBS’s documented --startstreaming launch parameter addresses one part: when OBS is launched with the parameter, it starts streaming. OBS also has Automatic Reconnect settings for a connection that drops while OBS is already running. Neither mechanism makes a powerless computer boot, restores an internet connection, or proves that a platform event has gone live. The OBS Studio overview describes reconnect separately from launch behaviour.
The Windows and YouTube steps below are examples, not universal instructions. This article does not cover verified firmware settings for restoring power after an AC outage, and the exact Task Scheduler screens can vary by Windows setup. Likewise, YouTube’s scheduled-event controls do not necessarily match another service’s workflow. Confirm the relevant documentation for your own combination before applying automation unattended.
It helps to draw the sequence on paper. For example: power returns, the PC boots, Windows starts OBS, OBS loads the intended scene collection, the network becomes available, the encoder connects, and YouTube displays the preview or live event. If the chain stops at any point, the remedy is different; adding a launch flag cannot repair every failure in the sequence.
Check OBS, sources and stream prerequisites
Before automating anything, open OBS normally and verify the setup you expect it to use. Save the intended profile and scene collection, then confirm the selected scene, media files, audio devices and any cameras or network inputs. An automatic launch that loads an old profile can connect successfully while showing the wrong content or no useful picture.
OBS’s Quick Start Guide recommends testing settings before relying on a stream. Use that principle here: watch the preview, listen to the audio, and confirm that overlays and transitions appear as intended. If the stream is a loop, check that playback continues past the point where it would normally restart. Do not assume a source that worked before a power cut will return in the same state afterwards.
Check the connection separately. OBS needs a working route to the platform and enough upload capacity for the configured stream. A router that has not finished reconnecting can leave OBS unable to reach YouTube even though the application has launched. If you are uncertain about headroom, review the practical guidance on upload speed for YouTube livestreaming, then test on the actual connection and at the settings you plan to use.
If your content is a devotional or family-oriented loop, the material itself is another prerequisite. Confirm that you have the rights and permissions needed for the audio, video and images you intend to broadcast. Automation will repeat whatever you have configured; it does not resolve content or audience-policy questions. A guide to running a 24/7 Tamil Murugan devotional stream can help you think through the channel’s continuous-stream setup beyond the restart mechanism.
Finally, confirm the stream destination and credentials while OBS is open. For YouTube, you need the correct stream key and server destination for the intended channel or event. Avoid leaving credentials visible in screenshots or sharing them with people who do not need access. The walkthrough for creating a YouTube live stream key covers that separate setup step.
Add the Windows shortcut parameter
OBS documents launch parameters for automation. On Windows, its Launch Parameters guide says to add the parameter after the executable path in the shortcut’s Target field. The parameter relevant here is --startstreaming.
First locate the OBS shortcut you intend to use, or create one that points to the installed obs64.exe. Open the shortcut’s Properties and inspect the Target field. It should contain the executable path in quotation marks, followed by a space and the parameter. The general form is:
"C:\path\to\obs64.exe" --startstreaming
That is an example of the field’s structure, not a claim about where OBS is installed on your machine. Keep the executable path that belongs to your installation, preserve its quotation marks, and place the parameter outside those quotes. If the path contains spaces and is not quoted correctly, Windows may not interpret it as one executable path.
Use the shortcut to test the launch. Close OBS first, then open it through the edited shortcut and confirm that it loads the expected profile and begins trying to stream. Check the OBS status and the platform’s receiving view, not just the application window. If you normally open OBS with a different shortcut, a startup entry or a scheduled task, that other route will not necessarily inherit the argument you added here.
Treat this as an application-start test, not an outage-recovery test. The shortcut can pass the parameter only when something launches it. It does not configure the computer to power on after electricity returns, wait for a router, or ensure that the stream destination is accepting a broadcast. Those steps need separate planning and verification.
Configure a scheduled launch with care
A scheduled task is one way to ask Windows to launch OBS at a chosen trigger, such as a user sign-in. The exact task options depend on the computer and the version and configuration of Windows, so use current Windows guidance for the interface rather than assuming a set of screens applies to every machine. The key OBS-specific detail is documented: for a scheduled task, OBS says to set “Start in” to the folder containing obs64.exe.
In the task’s action, use the path to the OBS executable as the program to start and add --startstreaming as the launch argument. Set the working directory to the directory where that executable is located, as OBS instructs. Check each field carefully: a correct argument paired with the wrong program path or working directory may fail to launch as expected.
Decide when the task should run and under which account, then test that exact trigger. A task that runs only after a particular user signs in is not the same as one that runs as soon as Windows boots. If the stream depends on a desktop session, audio device or other user-specific resource, changing the account or sign-in conditions can change the result. Do not select a more permissive or unattended option without understanding what it does on that PC.
Timing matters. If OBS launches before the modem or router has recovered, its first attempt to connect may fail. An OBS forum thread includes one Windows 11 user’s report of reconnect attempts happening before network equipment was ready; that is an individual report, not evidence that every setup behaves the same way. You can consider a delayed or network-aware launch, but the precise configuration was not verified for this guide. Test your own timing rather than relying on a delay value copied from someone else.
A task that launches OBS also does not necessarily detect that OBS has closed unexpectedly or that the broadcast has stopped. Decide who will check the channel and what they should do if the expected stream is absent. Avoid stacking several startup methods—such as a login shortcut and a scheduled task—until you know how they interact. Multiple launch routes can make diagnosis harder if more than one OBS process or window appears.
Set the YouTube destination and event behaviour
For YouTube, confirm that OBS is configured to send to the intended channel and stream key. YouTube’s encoder setup instructions describe connecting an encoder using the server URL and stream key. Recheck the destination after changing profiles or keys; an automated start is only useful if it sends the intended output to the intended account.
A scheduled YouTube event can involve a separate step from starting the encoder. YouTube’s instructions say to wait for the preview in Live Control Room and then select Go live for the scheduled-stream workflow. Its live stream settings documentation explains Auto-start and Auto-stop: when those settings are on, you can start or stop streaming from the encoder. The event’s settings therefore matter; a key and OBS’s launch parameter alone do not establish that every scheduled event will become public automatically.
Before relying on unattended recovery, check the actual event configuration and run a supervised test from the same kind of event you plan to use. Confirm whether Auto-start is enabled where appropriate, whether the event is scheduled or already live, and what YouTube shows when OBS connects. The distinction is useful: OBS may be sending video while the event still requires an action in Live Control Room, or the event may start from encoder output if its settings permit it.
Keep children’s-content rules separate from the restart configuration. Automation does not change whether a stream is set as made for kids or what features are available. YouTube notes that some features, including live chat, are disabled or restricted for streams set as made for kids. Its guidance on avoiding restrictions on live streaming also addresses streams featuring minors. Check the current official rules for your content and circumstances; do not treat a stream setting as a workaround.
Test a restart and power-loss scenario
Start with a controlled reboot test, with someone present. Save your OBS changes, close the application, and restart the PC using the method you expect to use in normal recovery. After Windows is ready, observe whether the intended shortcut or task launches OBS, whether the correct scene appears, and whether the sources return. Then check whether YouTube receives the encoder feed and whether the event is actually live.
A reboot is not the same as an outage. It tests the operating system and application startup path, but it may leave the router and other equipment powered continuously. To test a brief power interruption, do so only in a way that is safe for the equipment and appropriate for your setting, with an adult able to intervene. Do not deliberately interrupt power while a child is relying on the stream or while doing so could damage a computer, storage device or other equipment.
Record what happens at each stage rather than simply marking the test as passed or failed. Did Windows boot without an unexpected prompt? Did the task run under the expected account? Did OBS open the right profile? Did a camera return? Did the network reconnect before OBS attempted to stream? Did YouTube show a preview, and did the event become live? This sequence narrows the next troubleshooting step.
| Check | What a successful test should show | If it does not |
|---|---|---|
| Computer startup | Windows returns to a usable state after the test | Check the PC’s own power and boot configuration using current manufacturer or OS guidance |
| OBS launch | The intended shortcut or scheduled task opens the expected OBS setup | Review the executable, argument, task trigger and working directory |
| Sources | Picture and sound appear in the preview | Check each camera, file, audio device or network input independently |
| Connection | OBS connects after the network is available | Check the router, connection and encoder status; retest timing |
| YouTube event | Live Control Room shows the expected preview or live state | Review event type and Auto-start settings; follow YouTube’s current event instructions |
Do not use a single successful run to infer that every future outage will recover. The test establishes what happened under those conditions. A longer interruption, a delayed router, an update prompt or a changed key may produce a different result. Repeat the checks after material changes to Windows, OBS, the scene collection, the network or the YouTube event setup.
Monitor failures and plan manual recovery
Even a carefully tested launch path needs a person who can tell whether the stream is healthy. Decide how you will check it: for example, use YouTube Live Control Room to verify the event and stream health, and periodically inspect the channel from a separate device. For a children’s stream, make sure a responsible adult can intervene rather than assuming the computer will always recover without help.
If OBS is open but YouTube does not show the expected feed, first identify which link in the chain has failed. Check the OBS connection state, network availability, selected destination, stream key and event status. If the feed is present but the event is not public, follow the event’s controls in YouTube rather than repeatedly restarting OBS. Repeated restarts can obscure whether the original problem was the encoder connection or the event state.
If a camera or network source is missing, inspect that source separately. A broadcast may reconnect while a camera remains unavailable, or a media source may be paused at the wrong point. Have a safe fallback scene or a clear manual procedure if the missing source would make the stream unsuitable. Do not assume that restarting OBS will restore external devices, and do not leave an unintended picture or silence online while troubleshooting.
Keep a short recovery note beside the machine: how to check the preview, where the relevant event appears, who can access the channel, and how to stop the stream if needed. Store stream credentials securely rather than writing the key in an exposed note. If several people maintain the channel, agree who is responsible for checks after an outage and how they will hand over.
For an always-on devotional channel, the workflow may also depend on whether you are broadcasting a prerecorded loop or live sources. The article on looping video with OBS in India addresses a different part of that setup. Use it as a separate reference, not as evidence that a loop or a source will recover automatically after power loss.

FAQ
Does --startstreaming restart OBS after a power cut?
No. It tells OBS to start streaming when OBS is launched. Windows or another mechanism must first start the computer and launch OBS, and the network and destination must be ready as well.
Will OBS reconnect if the router is still restarting?
Not necessarily. OBS reconnect behaviour and network availability are separate, and a connection attempt can happen before the router is ready. Test the timing on your own setup and arrange a manual check if the stream does not return.
Does a connected OBS feed mean a scheduled YouTube event is live?
Not always. YouTube’s event type and Auto-start settings affect whether encoder output starts the event, and some scheduled workflows involve a Go live action after preview. Check the current event controls in Live Control Room and verify the public event during a supervised test.
Do these steps apply to macOS, Linux or other platforms?
The shortcut and scheduled-task instructions here are the documented Windows example, and the platform walkthrough uses YouTube. Check current OBS, operating-system and streaming-platform documentation for your own setup; do not assume the same fields or event behaviour apply unchanged.
