Change the camera source in OmeTV

The short answer

When you use OmeTV in a web browser, the camera and microphone it receives are usually chosen by the browser's permission settings for the site, not by a separate control inside the chat. To change the camera, select a different video device in the browser's site permissions, then reload the page. A camcorder can serve as that source only if the computer recognizes it as a camera. That normally requires either a camcorder with a USB webcam or streaming mode, or a USB video capture device connected to the camcorder's HDMI output.

Selecting a new camera does not automatically select a new microphone. Your speech may still come from the old webcam's microphone or the laptop's built-in microphone until you change the audio input separately.

Evidence gap: no documentation was available to confirm whether current OmeTV web or mobile versions include their own camera or microphone selector, or where it would be. The steps below rely on browser and operating system controls, which apply whatever the site itself offers. Menu names vary between versions, so check them against what appears on your screen.

Before you start: getting a camcorder recognized as a camera

A browser can only offer devices that the operating system lists as cameras. Most camcorders send video out over HDMI, and a computer's HDMI port is normally an output, so it cannot accept that signal. The usual fix is a USB capture device, which converts the HDMI signal into something the computer treats as a standard webcam. Some camcorders can also connect directly over USB in a webcam or live-streaming mode. Check your camcorder's manual to see whether it supports this.

• Use a camcorder setting that removes on-screen menus, icons and timecode from the HDMI output, often called clean HDMI or output display off. Otherwise those overlays may appear in the chat.
• Turn off auto power-off or demo modes so the camcorder does not shut down partway through a session.
• Use mains power if the camcorder supports it, because live output can drain a battery quickly.
• Close other apps that might be using a camera, such as video meeting software or camera utilities. On some systems, only one app at a time can use a camera.

What the camcorder route means for your audio

A capture device that carries HDMI audio often shows up as its own audio input, usually named after the capture device and not the camcorder. Choosing that input lets the camcorder's built-in microphone, or any external microphone plugged into the camcorder, capture your speech. The alternative is to keep using a separate microphone, such as a webcam or USB microphone, and use the camcorder for video only.

Each choice has a trade-off. A camcorder sitting farther away picks up more room sound, such as echo and background noise, than a microphone close to your mouth. Routing audio and video through different devices can also make speech drift slightly out of step with lip movement, because the capture device can add processing delay to the picture. If the delay is noticeable, try using the capture device's audio input so both signals take the same path. Whether this helps depends on your hardware, and no measurements are available here to quantify it.

Steps to switch the camera and microphone

• 1. Connect the camcorder, either directly by USB in webcam mode or through the HDMI-to-USB capture device. Turn it on, then confirm the operating system lists it as a camera.
• 2. Check operating system privacy settings. On Windows, open Settings, then Privacy & security, then Camera and Microphone, and make sure desktop apps, including your browser, are allowed access. On macOS, open System Settings, then Privacy & Security, then Camera and Microphone, and enable your browser.
• 3. Open OmeTV in the browser. If it asks for camera and microphone access, choose the camcorder or capture device as the camera and your chosen microphone as the audio input before allowing access.
• 4. If access was already granted to another device, open the site's permission controls. These are usually behind the icon at the left of the address bar. Change the camera and microphone selections there, or reset the permissions so the browser asks again.
• 5. In Chromium-based browsers such as Chrome and Edge, you can also set the default camera and microphone in the browser's privacy and site settings. In Firefox, the device choice is usually made in the permission prompt, so clearing the saved permission and reloading brings that prompt back.
• 6. Reload the OmeTV page so it picks up the new devices.

In the mobile apps, the camera choice is normally limited to the phone's own front and rear cameras. Connecting a camcorder is generally a desktop setup, and no evidence was available confirming external camera support in the OmeTV apps.

Checking that the intended input is capturing speech

• Video: your self-view should show the camcorder's picture, framed the way the camcorder is set up, and not the old webcam's view.
• Audio level: open the operating system's sound input settings and speak at your normal volume. The level meter for the selected input should move, and it should stay mostly still when you are silent. If the meter moves for a different device, that device is still the active input.
• Browser selection: open the site permission controls again and confirm the microphone listed is the one you intended.
• Partner check: in a conversation, ask the other person whether your voice sounds clear and whether your lips match your words. Hollow, distant speech usually means a far-away microphone is in use. Noticeable lag between speech and lip movement points to the sync issue described above.

If the camcorder does not appear

If the device is missing from the browser's list, the problem is usually earlier in the chain. Common causes include the camcorder not being switched to its output or USB streaming mode, a capture device the operating system has not recognized, a cable or adapter that does not carry the signal, or another app already holding the camera. Fix the device so it appears in the operating system's camera list first, then repeat the browser steps. If it still does not show up, the documentation for your camcorder and capture device is the authoritative source, since compatibility depends on the specific models.
