Here is an example stream.
https://vdo.ninja/?push=hh_42&webcam&autostart
HEIGHT 190
Simple link embedded with HEIGHT 190. To give permissions to camera and mic open in a new tab 
See Ninja PermaID. If embedding VDO.Ninja into a site as an IFrame, you'll not be allowed access to camera or microphones unless that IFRAME-element has allowed said permissions. See the documentation for more details - docs.vdo.ninja
# Quick Start: 1. Open VDO.Ninja: Visit https://vdo.ninja/ in your web browser (Chrome, Edge, Firefox, Safari). 1. Choose Your Source: Select "Add your Camera to OBS" to use your webcam or "Share your Screen" to stream your desktop or an application window. 1. Grant Permissions: Allow VDO.Ninja to access your camera and microphone when prompted. 1. Start Streaming: Click "Start" and copy the provided VIEW link.
# Share or Capture: Direct Sharing: Send the VIEW link to anyone you want to watch your stream. OBS Integration: Add the VIEW link as a Browser Source in OBS to capture the stream for your broadcast.
The smallest moving parts are: a stream id, a push URL (teacher), and a view URL (student). Add a password so the link is less “guessable”, and add clean output so the embedded view looks like a video panel, not a web app - docs.vdo.ninja
