NVIDIA Broadcast app installation appears to have stalled The NVIDIA Broadcast app installation will download the necessary files for your GPU during the installation procedure. The total download is around 500 MB. Depending on connection and internet speed, the download may take a while to finish.
If the installation stalls for more than 5 minutes without progress:
- Check if you are downloading anything.
- Right click on the Windows Bar > Task Manager.
- Go to Performance, and navigate to your internet device (Ethernet or Wi-Fi, as applicable).
- Check if you are receiving anything and the speed.
- If you are not receiving anything, or the speed is very low:
- Terminate the installation processes from Task Manager:
- Check your internet connection and make sure you have connectivity and a good download speed.
- Re-attempt the installation
Installation fails and shows a Camera install failed error Installation might fail for several reasons, including an internet disruption for a prolonged period. Just confirm your connection is back and try again. Please make sure you have enough disk space. The total required disk size during installation is ~1.5 GB.
Application shows an error that I don’t have a specific driver even though I do Reboot system and launch the application again. If the issue still persists, please close the application from the system tray and reinstall it.
How do I update the App? If an update is required you will receive a notification within the app asking you to update. To do so, follow these steps:
- Download the new version from the NVIDIA Broadcast app page
- The installer will automatically shut down NVIDIA Broadcast app and prepare to update it. In case the app does not close, you may force quit the app by pressing the Windows + R keys on your keyboard, which will bring up the Run command window, and typing the command below: Taskkill /f /im “NVIDIA Broadcast.exe”
- Install new version of NVIDIA Broadcast app
If you install the files over the app while it’s running and the AI Effects are enabled you may cause an installation error. In such case, you will notice that upon updating, when you try to turn on the Effects the app will give you an error. To fix this, just uninstall the application from Windows, and re-install it.
I changed my GPU and now NVIDIA Broadcast is giving me an error If you change your GPU to another NVIDIA Series GPU (i.e. from GeForce RTX 20 Series to 30 Series), the app will ask you to reinstall it, as it needs to download the AI models for your new GPU. In this case, close the app, and re-install it. During the re-install we will download the new models for you automatically.
NVIDIA Broadcast Issues
Microphone / Speakers
Unable to start the Noise Removal effect
To resolve this issue you may need to update your drivers and application. To do so:
The other person on the call/stream is unable to hear me
Make sure that your pipeline is set up correctly:
- Your microphone should be powered and connected to the PC. If the device has a mute button, make sure it’s off.
- In Windows you want to select your actual microphone device, and make sure that the volume is set correctly. To check this, right click on the speaker icon in the system tray > Open sound settings. Then under Input select your microphone. You can test the microphone there to make sure it’s correctly sending sound to Windows, and access the Device properties to adjust the volume.
- In NVIDIA Broadcast, go to Microphone and make sure that the microphone source is either pointing to Default Device, or your actual device.
- Finally, ensure that in your voice application configuration page the endpoint is set to Microphone (NVIDIA Broadcast).
Additionally, you may use the “Record your own sample” feature on the right pane of the Microphone tab to test your microphone and speaker.
I can’t hear anything on my headset / speaker
To solve this we need to make sure that your full audio pipeline is working properly:
- Make sure that your headset is working (i.e. on a wireless headset make sure it’s on, on other headsets with volume controls make sure volume is not muted).
- Make sure that the headset / speaker volume on Windows is not muted. You can do this by clicking on the speaker icon on the system tray in the bottom right corner. In Windows you should select your actual headset or speakers and adjust their volume.
- Check that your voice chat/streaming application is running the correct headset / speaker. If you wish to use NVIDIA Broadcast, the application should use the Speakers (NVIDIA Broadcast) device.
- Finally, review the configuration of NVIDIA Broadcast. Go to Speakers and make sure that your headset/speaker is selected as the Audio source.
You can use the test feature within NVIDIA Broadcast to check that the pipeline is audio working correctly.
Noise removal is not working for me
To use NVIDIA Broadcast AI Effects, your application needs to be set to use NVIDIA Broadcast
devices. To enable this, go to your app settings page, navigate to the Audio settings, and select NVIDIA Broadcast as your Input and Output devices. Step-by-step instructions can also be found in the NVIDIA Broadcast app Set Up Guide
Once you have confirmed that you are using the Microphone (NVIDIA Broadcast) device, open the NVIDIA Broadcast app and make sure that Noise Removal is turned on. You can test if the feature is working through the “Record your own sample” feature on the right pane of Microphone tab.
You will also want to make sure that if your application or device also has a noise removal feature you turn them off. If you use both the features may interact with each other. You can check out our NVIDIA Broadcast Setup Guide
for more information on what to adjust per application. My Microphone / Speaker is not listed in the NVIDIA Broadcast device source list
First, make sure that your device is available in Windows. To do this, right click on the Speaker icon in the systems tray > Open sound settings. Check there that your speaker or microphone is visible to Windows.
If your device is visible there but not on NVIDIA Broadcast, close the NVIDIA Broadcast app, unplug and replug your device, and open the app.
I can’t hear anything or they can’t hear me; I’m using the Default device
A common problem that people may experience is that they select an input device in NVIDIA Broadcast as the Default Device. This makes NVIDIA Broadcast use your Windows default device. If you have selected the NVIDIA Broadcast devices as your Windows’ default microphone or speaker, this will create a loop that will result in you not being able to record/hear any audio.
To solve it, we recommend changing your Windows default devices in the Windows Sound Settings panel to your actual devices.
I can’t change the strength of Noise Removal independently from Room Echo Removal That is expected. These 2 effects need to work in tandem and hence their strength levels are tied together. This is why you should see an indication next to the strength level of the effect. If I run Noise Removal and Room Echo Removal I get worse noise cancellation. Please note that Room Echo Removal is currently in beta. It is possible that when combining both effects, the noise removal effect loses a bit of its efficacy.
My webcam is not listed in the NVIDIA Broadcast device source list
Make sure that the camera is available in Windows. You can check this by opening the Windows Camera application. If the camera is available but NVIDIA Broadcast won’t recognize, try the following:
- Close NVIDIA Broadcast from the system tray.
- Unplug and replug the camera.
- Open NVIDIA Broadcast.
- If the camera is still not detected, please retry the above but connect the webcam to a different USB port on the system. If that still fails, reboot the PC.
Please note that at this point only webcams are supported by NVIDIA Broadcast. External cameras connected through dongles or capture cards are not officially supported.
When I select my webcam as the Camera Source the controls are greyed out
This means that your camera is in use by another application. Close the other app using the camera and re-select the camera in the NVIDIA Broadcast app. If that does not work, exit NVIDIA Broadcast from the system tray, and restart NVIDIA Broadcast.
I have selected an effect but it does not get applied on the camera feed immediately
On fresh installations, first time enablement of an effect can take up to 10 seconds.
I have selected an effect but it does not get applied on the camera feed
Please check if the effect status indicator is enabled, and that the effect strength slider is set to a non-minimum value. If the issue persists, exit the app from the system tray and restart it.
Background image or video does not display correctly in Background replacement
- Background replacement is optimized to use up to 1080p60 video. Using higher resolution videos may cause a performance impact.
- The aspect ratio of background images and videos is always preserved so you may observe frame cropping as necessary.
- Background replacement operates at the selected camera playback rate. Video playback will be adjusted by repeating or dropping frames as needed.
How can I improve the segmentation quality in Background removal, replacement or blur?
- You can optimize the features’ best quality and performance by setting the camera resolution at 720p at 30fps.
- For best results, keep the camera in the center, facing the subject. Having lighting on the subject helps improve quality.
- Accessories like hats, glasses, and other wearables can be challenging at times. The chair, microphone and headset will not be removed and should stay in the scene. If the microphone is not segmented properly, we recommend keeping it close to your body.
The camera preview is stalled/frozen when the system comes out of Sleep/Hibernate
If the NVIDIA Broadcast app is open and set to the Camera tab and the system goes to Sleep/Hibernate, you may experience a bug where the camera preview is stalled/frozen. To recover from this:
- Re-select the camera source in NVIDIA Broadcast.
- If the above fails, close the app completely from the system tray and re-open it.
The camera preview is stalled/frozen after updating my drivers
- Re-select the camera source in NVIDIA Broadcast.
- If the above fails, close the app completely from the system tray and re-open it.
I deleted the image/video that I was using for Background Replacement and now the app is unresponsive Close the application from the system tray and relaunch it.
I can barely notice a change with Video Noise Removal. Video Noise Removal is currently in beta. It helps remove the visual noise present in webcams. In well lit conditions and/or with premium webcams there may be limited visual noise, in which case the effect will be less noticeable. The effect works best on low light situations and it is particularly useful for laptop webcams.
My game FPS goes down a lot if I use NVIDIA Broadcast
The performance impact will depend on your GPU, game, webcam resolution and frame rate, and number of effects used during the broadcast. To reduce the impact on game FPS:
- Only turn on the Effects that you are actively using. Note that combining effects will have a significant impact on performance.
- If you don’t need to use your camera in full screen, reduce the camera resolution and framerate to 720p30.
Camera features are in Beta and don’t have all the performance optimizations implemented yet, so they have a higher performance impact on game FPS.
I have issues streaming my games while using NVIDIA Broadcast at the same time
- Ensure that your system meets the recommended minimum specification.
- Update Windows to 2004 or above, and turn on Game Mode and Hardware Scheduling.
- If needed, reduce the GPU load by adjusting game settings or capping your FPS.
A useful trick to prioritize your stream and avoid losing frames is to set your live streaming apps to high GPU priority. For example, in OBS Studio you can run OBS as Administrator.
Using NVIDIA Broadcast in 3rd party applications
After installing or updating the NVIDIA Broadcast app, the NVIDIA Broadcast Microphone/Speaker/Camera virtual devices are not showing up in 3rd party apps.
We recommend closing all 3rd party apps before updating/installing NVIDIA Broadcast. If you leave a 3rd party app open while NVIDIA Broadcast is updated/installed, it may not detect the new NVIDIA Broadcast virtual devices (Microphone/Speaker/Camera) until the app is restarted.
Camera (NVIDIA Broadcast) shows gray/black
This can occur if your webcam is in use outside of NVIDIA Broadcast. To solve this, close the application that is using your webcam and try again.
If you experience this after changing the resolution and/or framerate of the Camera source in NVIDIA Broadcast, reload the NVIDIA Broadcast camera by disabling and re-enabling, or restarting the third party application.
If I try to select custom settings in OBS Studio for the Camera (NVIDIA Broadcast) I see a gray image
Please configure the camera resolution and refresh rate from the NVIDIA Broadcast application. Upon changing the settings you will need to reload the camera (e.g. in OBS Studio, de-active and re-activate the camera in the camera settings), or reload the video chat or streaming application.
My video conferencing or live streaming application hangs if I select Camera (NVIDIA Broadcast)
The Camera (NVIDIA Broadcast) may be in use in some other third party application. Close the application that is using Camera (NVIDIA Broadcast) and try again.
I have issues using the Camera in my live streaming app
NVIDIA Broadcast exposes a virtual camera at Windows level that can be used by any app, and as such is compatible with a wide range of applications. However, due to how applications utilize webcams, there may be some functionality loss or incompatibility on some apps. You can check the list of apps that we have tested in the NVIDIA Broadcast app FAQ
If you are using Twitch Studio, this app has a webcam Auto-Optimize feature that adjusts resolution and framerate on the fly. This is not compatible with NVIDIA Broadcast, so you need to make sure to disable this feature before you select Camera (NVIDIA Broadcast) in Twitch Studio.
If you are using XSplit Gamecaster, please note that this app is not officially supported at this point. We are working with SplitmediaLabs to support it in the future.
I have issues using the Camera with Zoom NVIDIA Broadcast Camera is not currently compatible with the Zoom 64-bit client. It continues to work with the regular 32-bit Zoom client, irrespective of 32-bit or 64-bit operating system.
