If OBS loses its connection briefly, its automatic reconnect setting may help it reconnect; if the OBS application exits, that setting does not relaunch it. To recover from an OBS restart, arrange for your computer or a process supervisor to open OBS again, and use OBS’s --startstreaming launch option if you want it to begin streaming on launch.
Those steps address the encoder, not the continuity of a particular YouTube broadcast. YouTube’s auto-start and auto-stop controls affect how encoder signals interact with a broadcast, but you should test whether your event, watch page and archive behave as you need after a full restart.
A connection drop is not an OBS restart
A brief network interruption leaves OBS running. The application may still have its scene, media source and stream settings loaded while its connection to YouTube is unavailable. OBS’s automatic reconnect is intended for this kind of interruption. It can make another connection attempt, subject to its retry settings and the cause of the failure, but it does not control whether OBS itself remains open.
An OBS restart is different: the process has closed, perhaps because of a crash, an operating-system restart, a manual exit or a power interruption. Once OBS has exited, an OBS setting cannot make that closed process reopen. Something outside the application must start it again, and you must separately decide whether the new OBS session should begin streaming automatically.
That distinction matters for a loop channel. A network blip may interrupt delivery for a short period while the media source continues to exist in the running application. After an application exit, the source has to be loaded again and playback has to be checked. Neither case establishes that YouTube will keep the same broadcast open or that viewers will see an uninterrupted programme.
For a radio-style stream, the content itself needs a separate check: picture without sound is still a failure, and sound that clips can make a recovered broadcast hard to listen to. The practical checks in our guide to preventing clipping on a 24/7 YouTube radio stream apply after recovery as well as during normal operation.
Use automatic reconnect for brief interruptions
In OBS, open Settings and look under Advanced for Automatically Reconnect. Check that it is enabled, then review the available retry settings in your installed version. OBS’s overview documentation describes automatic reconnect as a response to a lost connection; it is not a watchdog for an application that has closed. See the OBS Studio Overview Guide for the documented setting, and check the current interface if the labels differ in your version.
Reconnect can be useful when the computer stays on and OBS remains open but the route to YouTube briefly fails. It cannot fix a persistent network outage, make a dead computer run, or restart an OBS process that has crashed. If you are seeing dropped frames rather than OBS closing, first distinguish a weak or unstable connection from an application failure. OBS’s stream connection troubleshooting guide discusses connection-related causes and checks.
Do not treat the reconnect control as a promise that every interruption resolves cleanly. During a test, watch OBS’s status and YouTube’s preview, then check the actual viewer experience from another device. Note whether the feed returns, whether audio returns with it, and how long the interruption is visible. If the setting is not helping, investigate the connection and the encoder output before adding unrelated launch automation.
A loop that resumes at an unexpected point may still be functioning as a source while the stream has experienced a disruption. Decide whether that is acceptable for your channel. A devotional programme may be better served by a clean restart at the beginning of a track, while an ambience scene may be acceptable if it resumes mid-video. You need to test your own source and make that editorial choice; automatic reconnect does not determine it.
Start streaming when OBS launches
OBS documents a launch parameter called --startstreaming. It instructs OBS to start streaming as the application launches. You can use it in the shortcut or launch configuration that opens OBS, rather than relying on someone to press Start Streaming after each relaunch. The OBS Project Launch Parameters documentation describes the option and how launch parameters can be used.
Treat this as a start instruction, not as a recovery guarantee. The parameter does not reopen OBS after it exits, choose a different scene if the intended one is missing, or prove that YouTube will attach the new encoder session to the same broadcast. It also does not replace checking the stream destination, media source and event state. It answers a narrower question: when this OBS launch occurs, should OBS attempt to start streaming?
A Windows shortcut can be configured with a target that includes the OBS executable and the launch argument, following the syntax in OBS’s documentation. On another operating system, use the equivalent application launch mechanism available there. Before relying on it overnight, launch OBS with the configured method while you are present and verify that the expected profile and scene load and that streaming begins as intended. Avoid assuming that a shortcut, scheduled task or supervisor uses the same user account and OBS configuration as your normal desktop launch.
If you prefer a deliberate manual check before broadcasting, do not add --startstreaming simply because it exists. A person can inspect the source and event before starting. Automatic start reduces that manual step but can also start an unintended scene or feed if the launch opens the wrong configuration. Choose based on the cost of a missed restart versus the cost of transmitting the wrong content.
Set up and verify the loop source
OBS can use video as a source, but the fact that a source exists in a scene does not prove that it is ready to play correctly after a restart. Open the scene you intend to broadcast and inspect the media source: confirm the selected file is the intended version, the source is visible, and audio is routed where you expect. OBS’s Quick Start Guide introduces adding sources, including video sources.
Check the source’s playback options in your installed OBS version and decide how it should behave when the file ends. For a single-file loop, verify that looping is enabled if you expect playback to continue from the beginning. Do not infer from a successful first launch that the source will necessarily resume at the same position after OBS exits; a full process restart is a new session. Test the actual exit-and-relaunch sequence with the same file and scene you plan to use.
Keep the media file at a stable location that the account used to run OBS can access. If it is moved, renamed or stored on a drive that is not available at launch, OBS may open without the expected media. A missing-file warning can be easy to overlook if streaming starts automatically. Include the source’s availability in your relaunch check, especially after an operating-system update or a change to storage.
For a playlist rather than one file, test transitions and repeat behaviour separately. A playlist that advances correctly during ordinary playback may behave differently after the application has been closed. If you are troubleshooting repeated items in another production setup, our article on stopping vMix from repeating the same video in a YouTube playlist covers a distinct playlist problem; the relevant lesson here is to verify the actual sequence rather than assume the source has recovered as intended.
Arrange a relaunch after OBS exits
Because OBS does not relaunch itself through automatic reconnect, decide what will start the application after an exit. For a setup that is attended, that may simply be a person checking the computer and reopening OBS. For an unattended channel, use an operating-system launch mechanism or process supervisor that is configured to start OBS if it exits. OBS’s launch documentation supports launching OBS with parameters; it does not turn OBS into a process watchdog.
A relaunch mechanism needs careful boundaries. If OBS exits because the computer is shutting down, no application-level relaunch can help until the computer is available again. If OBS repeatedly crashes on the same source or scene, automatic relaunch can repeat the failure rather than fix it. Arrange to receive or notice failure signals where possible, and investigate a recurring exit instead of allowing a restart loop to run unseen.
The launch configuration should use the OBS installation and user environment that contain the intended settings. Verify the account, profile, scene collection, media paths and stream destination from a controlled launch. As a suggested recovery check, confirm both the streaming configuration and the scene setup are present; do not rely on a remembered desktop session as evidence that a scheduled or supervised launch will use the same state.
There is a trade-off between faster recovery and more oversight. Adding --startstreaming can remove the need for a person to press the start button after OBS opens, but it also reduces the pause in which someone might catch a missing file or wrong scene. If the stream is sensitive or the source changes often, manual review may be preferable. If the content and configuration are stable, automatic start may be worth testing.
If a computer has to run around the clock, include its power and restart behaviour in the plan. The question is not only whether OBS starts after an exit, but whether the machine itself returns to a usable logged-in state and the launch mechanism runs. This article does not prescribe a particular supervisor or operating-system configuration: use documentation for your OS and test it under the account and conditions that will actually operate the channel.
Check YouTube’s event state after recovery
In YouTube Studio’s Live Control Room, confirm that OBS is sending to the intended server URL and stream key. YouTube explains that the stream key identifies where the encoder sends its feed in Manage live stream settings. Treat the key as a credential: do not publish it or include it in a screenshot, and replace it in OBS if it has been exposed.
Review YouTube’s auto-start and auto-stop settings deliberately. YouTube says these settings let you start or stop streaming from the encoder when they are enabled. Auto-start may reduce the need to press Go Live when encoder content arrives; auto-stop may end a broadcast after encoder content stops. Those controls change how YouTube responds to encoder signals, not whether OBS is relaunched. The same YouTube settings guide explains the controls; test their effect with your own event rather than assuming they preserve a particular watch page.
| Approach | What it addresses | What to verify |
|---|---|---|
| OBS automatic reconnect | A connection interruption while OBS remains open | Whether OBS reconnects and the feed returns |
External relaunch plus --startstreaming |
OBS has exited and is opened again | Whether the intended scene loads and OBS starts sending |
| YouTube auto-start/auto-stop | YouTube’s response to encoder start and stop signals | Whether the broadcast and watch page behave as intended |
| Manual start in Studio | A person decides when the broadcast begins or ends | Whether someone can attend and check the event |
If the same broadcast or watch URL matters, make that a test criterion. Official settings documentation describes the controls and their relationship to encoder signals; it does not establish that a full OBS process restart preserves the same broadcast object, watch page, archive or viewer continuity. YouTube’s guide to creating a live stream with an encoder also describes the stream workflow. Check the event in Studio and open the public-facing or unlisted watch page from another device after recovery.
Do not rely on the archive as proof that a restart continued the same event. YouTube Help states that streams under 12 hours are automatically archived, but that policy does not establish archive behaviour for a particular interrupted or restarted event. If an archive is important, verify it in the test and consult the current YouTube guidance for your format.
Test the failure and recovery path
Use a private or unlisted test broadcast before depending on the setup for an unattended night. YouTube recommends testing live-stream workflows and checking the stream; its live streaming tips are a useful starting point. Keep a second device on the watch page so you can see what a viewer sees, rather than judging recovery only from OBS’s status indicator.
Test a brief network interruption while leaving OBS open. Confirm that automatic reconnect is enabled, observe whether the encoder returns, and listen for audio as well as checking the picture. Then test a separate scenario in which OBS is fully closed and reopened through the method you plan to use. If you use a supervisor, verify that it detects the exit and launches the intended OBS configuration; if you use --startstreaming, verify that OBS attempts to stream on that launch.
After each test, check the loop source, YouTube Studio and the watch page. Confirm that the correct video is visible, sound is audible, the source behaves as expected, and the event state is acceptable. Make a note of whether the watch URL remained usable and whether the broadcast ended or required an action in Studio. These observations are more useful than assuming the result based on a setting name.
Repeat the test after meaningful changes, such as changing the stream key, media path, scene or launch method. You do not need to test every night, but a configuration that has never survived a deliberate restart has not been verified for that failure. A short attended test can reveal a missing source or wrong account before it becomes an overnight problem.
For a 24/7 channel, also decide who notices a failure that relaunch cannot fix. Automatic actions can reduce the need for someone to press a button, but they do not tell you whether the returned stream has the right content or whether the public event is still available in the way you intended. If your main concern is not OBS relaunch but scheduling recurring pre-recorded broadcasts, see our guide to scheduling recurring YouTube livestreams from pre-recorded videos for that separate workflow.
When a restart test behaves differently from the normal launch, simplify the recovery path. First launch OBS manually and verify the source and destination. Then add the launch argument, test again, and only then introduce the external relaunch mechanism. Changing one part at a time helps identify whether the failure comes from the source, OBS configuration, the operating system or YouTube’s event controls.

FAQ
Does OBS automatic reconnect restart OBS after it closes?
No. Automatic reconnect is for a connection interruption while OBS is running. A separate operating-system mechanism or process supervisor must reopen OBS after it exits.
What does --startstreaming do?
OBS documents --startstreaming as a launch parameter that starts streaming when OBS launches. It does not relaunch OBS after a crash or guarantee that YouTube continues the same event.
Will YouTube keep the same live event after OBS restarts?
Do not assume that it will. YouTube’s encoder and auto-start settings do not promise continuity of the same broadcast, watch page or archive after a full OBS process restart, so test your exact setup.
Should I enable YouTube auto-stop for a 24/7 loop?
Choose based on how you want YouTube to respond when the encoder stops. Auto-stop can end the broadcast after content stops, so test with an unlisted or private event if retaining a particular event matters.
