OBS Face Swap for Live Streaming and Video Calls

For OBS face swap streaming, use Start Streaming to send the OBS scene and its audio mix to Twitch or YouTube. For a video call, use Start Virtual Camera to send the scene as a camera feed, then pick a microphone in Zoom, Google Meet, or Teams.

Start in the Live Face Swap workspace and follow the Windows OBS capture guide to capture and crop the live result. Play back a short OBS recording before connecting a platform. Check that the processed picture moves, the original camera inset is outside the crop, and your voice comes through if you plan to stream it.

For a clean Prism source, use Open OBS output in the studio and capture Live Face Swap Output in OBS. The current output guide covers Windows and macOS. This article covers what to do with the scene once OBS receives it.

Fix a missing camera, wrong scene, or silent call

• OBS Virtual Camera is missing. Start it in OBS first, then fully reopen the desktop meeting app or reload the Meet tab. Check Windows camera access and, for browser calls, the meeting site's camera permission. If Start Virtual Camera itself is missing from OBS, check the virtual camera installation.

• The preview is black or shows the wrong scene. Check that the face swap is still moving in the browser and in OBS. Verify the virtual camera output target and the camera selected in the meeting app. If the app has its own video effects on, clear them while testing the feed.
• The picture works but there is no sound. The virtual camera carries video. In calls, select and test the microphone in the meeting app. On Twitch or YouTube, check the microphone level and mute state in the OBS Audio Mixer.

When you finish a call, turn off meeting video and stop the virtual camera. When you finish a stream, follow the steps for your platform and confirm the broadcast has ended. Then return to the workspace and choose End session to stop AI generation.
