Why doesn't my webcam video play in the web page?

If your webcam video requires Basic HTTP Authentication (its URL starts with http://user:auth@host…) and you embed this video in your page by using the <img> or <video> tag, it probably will not work because authentication for embedded content is not allowed in Android Webview (or in Google Chrome on Android) for security reasons. For more information, please read the discussion on this topic at Chromium Bugtracker. This is something Fully cannot change. The only known workaround is to use the video proxy.

If your website is loaded as an HTTPS document and your webcam URL is HTTP, it might be blocked because secure and non-secure content cannot be mixed. You can try changing the Mixed Content Mode option as a workaround. However, Android Webview 111+ has a known bug and often blocks all mixed content, so this option doesn’t work anymore.

If your camera stream is RTSP you can’t embed it into your website with <video> tag as this is not supported by the Webview. Check this FAQ for alternatives.
