Overview
Video downloader & web video caster: detect videos in tabs, download MP4/WebM, cast HLS/M3U8 streams to Chromecast or Google TV.
CastBrowser detects compatible video streams in the browser tab you are viewing and gives you three simple actions: play, save, or send to your TV. KEY FEATURES - Automatic video detection - a toolbar badge shows how many compatible items were found in the current tab. - MP4, WebM and HLS support - identifies direct files and M3U8 playlists as they load. - Built-in preview - check a file before you save or send it anywhere. - Direct download - save compatible MP4 and WebM files to your computer for offline viewing. - Google Cast playback - send supported media to Chromecast, Google TV, Android TV, or a television with Chromecast built in. - HLS quality selection - choose from available resolutions, frame rates and bitrates when a compatible master playlist provides multiple options. - Useful details - review format, resolution, duration and file size when available. HOW IT WORKS 1. Open a page containing video. Start playback if nothing has appeared yet. 2. Look for the numbered badge on the extension icon. 3. Open CastBrowser to see what was found in that tab. 4. Choose Cast, Play or Save. 5. For television playback, keep your computer and your Google Cast device on the same Wi-Fi network. FORMAT SUPPORT Direct MP4 and WebM video files can usually be previewed, saved or sent to a TV. HLS/M3U8 adaptive streams are detected and can be selected by quality and sent to a supported Google Cast device. Results depend on the source website, the format, your browser, your network and the receiving device. WHO IT IS FOR - Anyone who would rather watch on a big screen than a laptop. - People keeping lecture recordings, webinars and tutorials for offline study. - Researchers and archivists saving a copy of material they have rights to. IMPORTANT Use CastBrowser only with media you own or have permission to access, save or stream. CastBrowser does not host or provide content and does not bypass DRM, paywalls, sign-in requirements or website restrictions. YouTube and DRM-protected services are not supported. PRIVACY Detection and the results list are processed locally by the extension. No CastBrowser account is required. TV casting uses a sender page hosted
