Here are some of our most frequently asked questions and suggestions on troubleshooting. Feel free to join the Streamlabs OBS Discord for further support with any questions or issues you might have.

 

Reporting issues

You can submit any issues you have and general troubleshooting steps do not help or is not available, on our Streamlabs OBS tracker.

When doing so, and if you are able to do so, please Upload cache to Developers which you can find in the settings, and include the file name you get by doing so in the issue.

Preferably also include your Discord with #discriminator in the issue so a developer can contact you to try a few things out to resolve this issue.

 

Feedback

We greatly appreciate all of your feedback! We are working diligently to incorporate it into future releases. 

You can submit any suggestions or ideas you have on http://ideas.streamlabs.com. And feel free to post a link in #suggestions on the Streamlabs OBS Discord. Make sure to check if the idea already has been proposed so you can just upvote it and place a comment in that post.

 

 

First Troubleshooting Step

Make sure you have up-to-date software and drivers at all times when encountering issues, especially video drivers. Sometimes it even helps to fresh reinstall your video drivers.

If you have never installed OBS Studio before, check if your system has Visual C++ 2015 Redistributable has installed, and maybe also 2017. It never hurts to have both of them installed as other applications could be dependent on this as well. You can find the installers via Microsoft Support.

 

Game optimized encoder settings

The game optimized encoder settings is currently only available when using software (x264) encoding. You can enable the optimized encoder settings when you go live, in the pop-up where you set the game and title, you can now also enable optimized encoder settings.

  • Medium profile; CPU usage equivalent to x264 profile veryfast but optimized for gameplay.
  • Low profile; CPU usage equivalent to x264 profile ultrafast but optimized for gameplay.

This mode sets custom x264 options and thus overrides any options you have manually set. The options that are set are determined by machinelearning.

If you do not see the pop-up to set the game or title, make sure that Confirm stream title and game before going live is set found in the General Settings.

 

Cannot maximize or open SLOBS from Taskbar

If your Streamlabs OBS is open but you are unable to see the window, but it is on the taskbar where you see a preview of the window please select the program so it is highlighted on the taskbar. Then you press left alt and spacebar. This should open a context menu on the top-left of your screen, where you select Maximize.

 

Update is stuck

If you encounter this issue where the updater is stuck at a certain percentage, please download the latest version from the Streamlabs OBS website and run the installer as administrator. There should be no need to uninstall or delete any data prior doing so.

 

Streamlabs OBS crashes during startup

  1. Try starting Streamlabs OBS as administrator.
  2. Update your graphic card driver if needed and try again.
  3. Delete C:\Program Files\Streamlabs OBS\resources\app\node_modules\obs-studio-node\distribute\obs-plugins\frontend-tools.dll
  4. Try disabling your Anti-Virus Software and/or allow Streamlabs OBS in the firewall.
  5. Reinstall with the latest installer from the website

 

 

 

Not capturing desktop audio

The developers are currently aware of the issue for some users unable to capture desktop audio. Some audio management software, like Nahimic 2 or motherboard audio software like Realtek HD Audio Manager or Sound Blaster Recon are known to cause issues. Try closing that kind of software, and also check Windows taskmanager if any processes with a similiar name are running to be closed.

You can also try first to select manually the desktop audio device (audio settings), you use as default device in Windows Sound, not setting it to default. Alternatively you can set it to disabled and add in the scene you want desktop audio an Audio Output Capture and select the device that is set as default device in Windows Sound.

As last resort, you can temporary use an alternative program to capture audio like VoiceMeeter Banana. This program allows you to set it as default device, and then use a virtual audio cableinto Streamlabs OBS to capture the desktop audio. You can find various guides on the internet (like this one) or Youtube.

 

Not going live on the service

Developers are currently aware of the issue. You can try the following;

  1. Go to Stream in settings and select a different service than you want to use.
  2. Restart Streamlabs OBS.
  3. Go to Stream in settings and select the service again you want to use.
  4. Select a different server, and then the server you want to use (do not use auto)
  5. Restart Streamlabs OBS once more.
  6. Try going live.

If this did not work, please upload your cache to the developers (found in General Settings) and with the filename, that got copied to your clipboard by doing so, create an issue on the SLOBS Tracker. Describe the nature of the issue and post the filename of your cache as well.

 

Recording is not working or saved

 

 

Please install Visual C++ 2015 redistributable as described above.

 

My Elgato HD60 is not capturing audio

  1. Make sure your Video Capture Device is set to Elgato Game Capture HD and not Game Capture HD60 S (Video) (#01)
  2. If the above option doesn’t work for you, try running a 3.5mm audio cable from your monitor (headphones, if available) to your line-in on your PC. Then use an Audio Input Capture Source in a scene you want to have the Elgato audio, and select the line-input. You might want to add a small “Render Delay” Filter to the Elgato Video Capture Device to resync with the audio.

 

High CPU usage in Idle

  • Make sure all drivers are up-to-date and are matching 64-bit versions of your system.
  • Almost every source you use, uses CPU to be functioning properly. The more you have the higher the total CPU usage would be.
  • Downloaded animated overlays can cause high CPU usage due to the webm video files used as overlays.
  • Using many different browser sources can cause high CPU usage, try limiting them or create references.
  • You can delete Streamlabs OBS browser source cache that can cause high CPU usage;
    1. Navigate (or winlogo + r) in Windows to %appdata%\slobs-client\plugin_config\obs-browser
    2. Delete Cache
    3. Start Streamlabs OBS again

 

Twitch Chat is not loading

Apparently, having another streamers channel open, in your own normal browser, while you have Streamlabs OBS open will cause your the chat window to not work properly. Only solution as of right now is to just simply not have another Twitch Chat open in your normal browser while you are using Streamlabs OBS.

 

Game or Stream is stuttering or having FPS drops

These is most likely caused by overloading either the GPU and CPU. At all times keep and eye out for both the total CPU and GPU usage in Windows task manager (if you do not have GPU in Windows 10, update to the latest major update). Some games are known to be broken and like to use all available CPU or GPU resources and cause issues for streaming software.

If you are using software (x264) encoding and are running into high CPU usage issues, causing skipped frames, consider using a faster preset or start using hardware encoding (NVENC/AMD) as that wont load the CPU extra to encode the stream.

Having high GPU usage? Lower the graphics quality in game so streaming software gets more breathing room to compose the frames for the encoder. Regardless of software or hardware encoding, streaming software requires shared GPU to compose the frames (combine sources) for the encoder to encode. Having overloaded GPU will cause lagged frames.

If you are having dropped frames this is most likely the network/internet connection to the selected server. Try selecting the closest Twitch server manually (not auto), and if already done so, try another (like 2nd closest) server. You can also try to restart your local network gear (modem, router, and switches) and see if that helps. Ultimately you can test different connections to the Twitch server with this tool, as your ISP routing can be messed up as well.

In addition to the dropped frames, make also sure the video + audio bitrate is not exceeding or is getting close to your internet upload speed. Having other users on same network using upload (like cloud storage) will lower the throughput of the upload.

summary;

  • Lagged Frames; Compositor overloaded, commonly high GPU usage.
  • Skipped Frames; Encoder overloaded, commonly high CPU usage on x264.
  • Dropped Frames; Network issues, try other servers or restart equipment.
