Using the OBS virtual camera on Ome.tv

The short answer

To use OBS on Ome.tv, start the OBS virtual camera, then choose it as the camera when Ome.tv (or your browser) asks for camera access. The main limitation for speech is that the OBS virtual camera carries video only. It does not send OBS audio. Ome.tv will hear whatever microphone the browser is set to use, chosen separately from the camera. That can be the microphone built into your webcam, a USB or headset microphone, or a virtual audio device if you want OBS-processed sound.

The supplied evidence does not say whether Ome.tv permits, restricts or detects virtual cameras. Check its current terms and behavior yourself before you rely on this setup.

Why audio and video are separate in this setup

A browser treats cameras and microphones as two independent kinds of input device. The OBS virtual camera appears to the system as a camera with no audio stream, so selecting it changes only your picture. Any filters you add to an audio source inside OBS, such as noise suppression, a noise gate or a compressor, are not heard on Ome.tv unless you route that audio out of OBS separately.

There is a useful consequence for webcam microphones. Most USB webcams register their microphone as a separate audio input device. OBS can then use the webcam's video while the browser still captures the webcam's microphone directly. Whether a particular webcam's microphone stays available while OBS holds its video depends on the device and its driver, so confirm it with the check below.

Before you start

• A recent version of OBS Studio with the virtual camera feature. On Windows and macOS it is built in. On Linux it typically depends on the v4l2loopback kernel module.
• A camera source already working in an OBS scene. This can be a webcam, or a mirrorless camera connected through a capture card or the manufacturer's webcam utility.
• A microphone you intend Ome.tv to use: the webcam's built-in mic, a separate USB or headset mic, or a virtual audio device.
• A browser that Ome.tv supports, with permission to use the camera and microphone.

Step-by-step setup

• 1. Open OBS and build the scene you want people to see. Check that the camera source shows a live picture in the preview.
• 2. Click Start Virtual Camera in the OBS Controls panel. Leave OBS running for the whole session, because closing it stops the virtual camera.
• 3. Open Ome.tv in your browser. If the browser was already open, reload the page so it detects the new camera device.
• 4. When the browser asks for permission, allow camera and microphone access.
• 5. In the camera choice, select the OBS virtual camera, usually listed under a name such as OBS Virtual Camera.
• 6. In the microphone choice, select the specific microphone you want. Avoid a vague default entry if you are unsure what it points to.
• 7. If you missed the prompt or chose the wrong devices, open the site permission settings for the page in your browser. These are usually reached from the icon at the left of the address bar. Change the camera and microphone there, then reload Ome.tv.

Menu names and locations vary between browser versions, operating systems and OBS releases. Treat the wording above as a guide and check the labels on your own system.

Using a mirrorless camera as the video source

A mirrorless camera reaches Ome.tv through the same path. Bring its feed into OBS, usually as a Video Capture Device fed by a capture card connected to the camera's clean HDMI output, or by the maker's webcam software. Then send it out through the virtual camera.

For audio, do not assume the camera's microphone travels along. Sound embedded in an HDMI capture feed lands in OBS, not in the browser. If you want Ome.tv to hear the camera's mic or a mic plugged into the camera, you need to route OBS audio out as described below. The simpler choice is to give the browser a separate microphone.

If you want OBS-processed audio on Ome.tv

To have Ome.tv hear audio after OBS filters, send OBS output to a virtual audio device and choose that device as the microphone in the browser. This needs third-party virtual audio software, or the OS-level routing tools available on Linux. OBS does not provide it on its own. One common approach is to set the device as the OBS monitoring output, with your audio sources set to monitor.

This chain adds steps where silence, doubled audio or echo can appear. Use it only if the filters clearly improve your speech. The evidence supplied here does not cover specific tools or their settings.

Confirm the right microphone is capturing your speech

• Watch your operating system's input level meter while you speak at normal volume. Windows shows one in its sound input settings; macOS shows one in the Sound input pane. The bar should move for the device you chose in the browser, and stay still when you are silent.
• While Ome.tv is open, look for the browser's recording indicator on the tab or in the address bar. It confirms the page is using a microphone, though not always which one.
• Open the site permission settings for Ome.tv and read the microphone name. It should match the device whose meter moved.
• If you route OBS audio through a virtual device, check that the OBS audio mixer shows your voice and that the virtual device's input meter moves too.
• Where possible, ask a chat partner whether you sound clear, with no echo and no long gaps at the start of sentences. A gap at the start can mean a noise gate set too aggressively.

Common problems

Symptom | Likely cause | What to try

OBS virtual camera missing from the camera list | Virtual camera not started, or the page loaded before it started | Start the virtual camera in OBS, then fully reload the page or restart the browser

Black or frozen picture on Ome.tv | OBS closed, the virtual camera stopped, or the scene shows no live source | Keep OBS open, confirm the preview is live, restart the virtual camera

Others cannot hear you | Wrong or muted microphone chosen in the browser, or expecting audio from the virtual camera | Choose the correct microphone in the site permissions and check its OS input meter

Your voice echoes for the other person | Speaker sound reaching the microphone, or the same audio sent twice through monitoring | Use headphones, and do not monitor a mic in OBS while the browser captures that same mic

Webcam mic stops working once OBS uses the camera | Device or driver does not share the mic while video is in use | Use a separate microphone, or route the webcam mic through OBS to a virtual audio device

What this guide cannot confirm

No source specific to Ome.tv was available. This guide cannot state whether the service limits virtual cameras, how its mobile apps handle them, or what exact device menus its web interface shows. The steps rest on how OBS's virtual camera and browser device permissions generally work. Check each step on your own setup.
