Streamlabs Desktop’s media-file caching keeps decoded frames in memory so looping media does not need to be decoded repeatedly. The documented toggle is in the Advanced settings area, though the exact path or label may differ between releases.
That feature is not the same as a browser-source cache, and neither is the same as the broad “Clear Cache and Restart” reset. Start by identifying the symptom, then try the narrowest relevant change; back up your scenes before any broad reset.
Identify which cache or symptom you mean
People use “cache” to mean several different things in Streamlabs Desktop. A looping video or other media source may be affected by decoded media-frame caching. A browser source showing a web page may be affected by browser-rendering cache. A general application fault may lead you to the broad reset action, which can remove user data. These are separate mechanisms and steps.
Start with what you can observe. If a looping local file stutters, or CPU use changes when it plays, the media-file caching toggle is a reasonable setting to investigate. If a browser source shows stale web content or fails to display a page, consider the browser-source cache instead. If Streamlabs itself will not behave normally, do not assume that clearing one of those caches is the answer: a full reset is a different and riskier intervention.
Write down the source involved, when the fault occurs, and whether it repeats after a restart. For a devotional channel, for example, a video that stutters each time a bhajan loop returns points you towards the media source. A browser panel that keeps showing an old page points towards the browser source. The distinction prevents you from deleting unrelated data while trying to fix one symptom.
A cache is not necessarily a folder of media files that you should remove. Streamlabs describes media-file caching as holding decoded frames in memory. Treating that as a disk-clean-up task can send you towards the wrong setting or a much broader data deletion.
Find the documented media-caching toggle
Streamlabs’ article on media-file caching says the feature can be switched in the Advanced settings area. Open Streamlabs Desktop’s settings, look for Advanced settings, and find the media-file caching option. Verify the wording in your installed version rather than relying on an exact sequence of menu clicks from an older guide. The Streamlabs media-file caching explanation describes the feature and its intended behaviour.
If the setting is present, note its current state before changing it. Change only that setting, then test the same media source under similar conditions. If the option has moved or the label differs, stop and consult current Streamlabs support material rather than guessing at a setting that sounds similar. The cited Streamlabs article was last updated on 28 January 2022; it does not establish a menu path for every current release.
You do not need to clear a folder to enable this feature. It is a toggle governing how decoded frames are reused, not an instruction to collect your media in a special cache directory. Keep the original media file where your scene expects it, and avoid changing several source properties at once if you want to know whether the toggle made a difference.
Before making a change during a live broadcast, consider whether you can test it outside the channel’s main schedule. A setting adjustment may be easy to reverse, but testing during a scheduled programme can still interrupt the output. If the channel depends on an uninterrupted loop, note the current settings and choose a quiet maintenance window.
Understand the performance trade-off
Decoding media takes processor work. Streamlabs says its caching feature stores decoded frames in memory so a looping source can reuse those frames rather than repeatedly decode the same media. The intended trade-off is less repeated CPU work in exchange for memory use. This is Streamlabs’ account of its own feature, not a guarantee that every source or computer will behave the same way.
Streamlabs reported more than 35% CPU usage reduction in its internal measurements from 2019; its article was last updated on 28 January 2022. That is a historical vendor-reported result, not an independent benchmark or a prediction for your machine. The article also described a 2 GB limit for the cache: decoded frames beyond that limit would not be cached. Treat those figures as details reported in that article, not verified specifications for every present-day build.
The article says the application can reduce its cache use when local memory use spikes. That does not make memory use irrelevant. If your machine is already under memory pressure, a feature that keeps decoded frames available may have a different practical effect from one on a machine with more headroom. Conversely, turning caching off may mean more repeated decoding for looping media. Neither choice is automatically best.
A useful test is a controlled comparison, not a one-time impression. Keep the same media source, scene, resolution, and other workload as stable as practical. Observe whether the original symptom changes after toggling the feature and restarting or replaying the source as appropriate. Record whether CPU load, memory pressure, or the visible stutter changed. If nothing changes, return to the original setting and investigate other causes instead of assuming that cache adjustment is required.
If you run a playlist from local files, source order and transitions may matter as much as decoding. A separate guide to why VLC playlist order can change during a YouTube live stream can help when the actual fault is sequence rather than playback performance.
Separate media cache from browser-source cache
A browser source loads web content; its cache relates to that browser-rendering component. It is not the memory used for decoded frames from a looping media file. If the symptom is stale or broken content in a browser source, a browser-specific cache step may be relevant. If a local video file is stuttering, deleting browser data is unlikely to address the media-frame setting you are investigating.
Streamlabs’ public support repository documents a Windows browser-cache location under %appdata%\slobs-client\plugin_config\obs-browser\Cache, followed by restarting Streamlabs Desktop. The Streamlabs Desktop support repository is the primary reference for those support instructions. The path is Windows-specific; those instructions do not establish an equivalent location for macOS. Do not apply a Windows path to another operating system or infer that deleting a similarly named folder is safe.
Before touching the browser cache, close the application and confirm that the symptom is actually in a browser source. Follow current Streamlabs support guidance for your installed release and operating system. If you are unsure whether the folder is the correct one, do not widen the deletion to a parent directory. Removing a specific browser cache is not the same as erasing Streamlabs user data, but a mistaken target can turn a narrow cleanup into a broader loss.
There is also a distinct media-source behaviour in OBS documentation: “Close file when inactive” can unload a media file while its source is hidden or off-scene, with a possible delay when it loads again. That is useful context if you use more than one streaming application, but it is not equivalent to Streamlabs’ decoded-frame caching toggle. The OBS Project media-source documentation describes that separate option. Do not assume a similarly named feature in one application has the same effect in another.
Try narrow troubleshooting before a full reset
Use the symptom to choose one low-impact test at a time. For looping media, note the media-cache toggle, change it only if the installed version exposes it, and replay the same source. For a browser source, address only that browser source’s problem and consult the vendor’s operating-system-specific instructions. For a file that appears to be in the wrong order, check the playlist or source sequence rather than clearing unrelated caches.
Check ordinary causes alongside the cache setting. Confirm that the media file still exists at the path used by the source, that the source points to the intended file, and that the fault can be repeated. If only one file fails, test another known-good file in the same source type. If all sources fail after a change elsewhere, the cache may be incidental. These checks keep you from resetting a working scene collection to fix a missing or unsuitable media file.
For channels built around a static background, the file and source configuration may be simpler than a long video loop. The guide on showing a static image during a 24/7 meditation stream covers that use case; it is not a cache-clearing procedure, but it can help you distinguish an image-source setup from a looping-media problem.
Avoid changing the cache toggle, reinstalling the application, deleting folders, and rebuilding scenes in one sequence. If the issue disappears, you will not know which change mattered; if it worsens, restoring the previous state becomes harder. Keep a short note of each change and its result. If a narrow step does not help, undo it where practical before moving to another troubleshooting path.
A broad “Clear Cache and Restart” action is not a harmless equivalent of clearing temporary browser content. Streamlabs’ getting-started guidance describes it as a start-from-scratch action that wipes user data. Its troubleshooting guidance warns that scene collections and settings may be lost when cache data is cleared. Contact Streamlabs support before taking that step if the problem remains and you cannot confidently restore your setup.
Back up scenes before resetting
Before any broad reset, export your scene collections and preserve any other information you would need to rebuild the channel. Streamlabs support guidance recommends exporting scene collections as a backup; its repository also warns that a full user-data clear can require signing in again and rebuilding settings or scenes. A backup is useful only if you know where it is and can access it after the reset, so keep it outside a directory you plan to clear.
Make a simple inventory of items that are easy to overlook: scene names, media file locations, browser-source addresses, audio routing, and any settings you would not remember. If your channel uses a series of scenes for a local news loop or language-specific playlist, record their intended order. The goal is not to make a perfect manual copy of every setting; it is to avoid discovering after a reset that a key source or file path was never recorded.
Do not treat deleting %appdata%\slobs-client as routine cache cleanup. The Streamlabs support repository describes clearing that area as clearing user data, not as a narrow media-frame cache procedure. If official support asks you to perform a broad reset, follow its current instructions and make the backup first. If you have no export or cannot establish what a reset will remove, pause and ask support rather than improvising.
There is a real trade-off: a clean reset may be appropriate when the application has a persistent fault that narrower steps cannot resolve, but it costs time and can remove configuration you rely on. For a channel that is expected to run unattended, rebuild time is part of the operational risk. Schedule any approved reset when you can test the scenes and output before the next broadcast, not minutes before a programme is due to begin.
Check whether the issue persists
After a change, reproduce the original symptom as closely as possible. Use the same file or browser page, the same scene, and a comparable playback interval. Check both what viewers would see and what you can observe locally. A setting change that reduces a task-manager reading but leaves the actual stutter unchanged may not solve the problem that matters to your channel.
Test a complete loop if the fault happens at the end or beginning of a file, rather than judging only the first few seconds. For a browser source, refresh or reopen only as current guidance recommends and check whether the expected content appears. Avoid claiming a fix based on one successful restart if the problem normally occurs later in a long session; leave enough time to see whether the same fault returns.
If the issue persists, restore any test setting that made things worse and write down what you tried. Include the Streamlabs Desktop version, operating system, source type, the exact symptom, and whether it affects one file or every source of that type when asking support. That is more actionable than saying only “the cache is broken”. Do not delete more data simply because the first cache-related step did not work.
For a 24/7 channel, a desktop troubleshooting result also needs an operating plan. If your computer must remain on for the broadcast, account for local power, network, and application failures separately from the media-cache setting. When your particular pain is having to keep the computer on just to repeat a prepared file, StreamNeo removes that specific burden by letting you upload a video and run it as a YouTube live stream without your computer switched on. It does not diagnose Streamlabs cache behaviour or replace checking your scenes and source files.
If the channel instead depends on playlist rotation, automation and source arrangement are separate problems from caching. The guide to rotating YouTube livestream playlists by Indian language with FFmpeg is relevant when rotation is the issue, not as a remedy for a Streamlabs browser or media cache.

FAQ
Does media-file caching store my video files in a folder?
No. Streamlabs describes it as keeping decoded frames in memory so looping media can avoid repeated decoding. Do not look for a media-cache folder to delete as a way to switch the feature on or off.
Where is the media-file caching setting?
Streamlabs’ article documents a toggle in the Advanced settings area. The article was last updated in 2022 and does not establish an exact path for every release, so check the labels in your installed version or consult current Streamlabs support.
Should I use “Clear Cache and Restart” to fix a stuttering video?
Not as a first step. First check the media-file caching toggle and the media source itself; the broad reset can wipe user data, including settings or scene collections. Export your scenes and consult Streamlabs support before considering it.
Can I clear the browser-source cache on macOS using the Windows folder path?
No. The cited support instructions give a Windows-specific path and do not establish a macOS equivalent. Use current instructions for your operating system rather than adapting a Windows directory by guesswork.
