To make the migration even clearer, here is a full before/after comparison.
: VHS is built directly into the Video.js core. It relies on Media Source Extensions (MSE) to deliver adaptive bitrate streaming on most modern browsers.
To maintain backward compatibility, an alias was kept: when you wrote player.tech_.hls , it still pointed to the VHS tech for a while. Starting with certain Video.js versions (typically v7+ with updated contrib packages), using the old name triggers this deprecation warning.
If your scripts must run across different legacy sites, wrap your logic in basic feature detection to prevent runtime crashes: javascript To make the migration even clearer, here is
ngAfterViewInit() this.player = videojs(this.videoElement.nativeElement); this.player.ready(() => const hls = this.player.tech_['hls']; // warning );
| Browser | Native HLS Support | VHS Behavior | |---------|-------------------|---------------| | Safari (macOS/iOS) | Yes | Can override native (configurable) | | Chrome/Edge/Firefox | No | Uses VHS engine | | Android Chrome | Varies | Uses VHS for reliability |
Let's walk through a complete migration from a legacy HLS setup to modern VHS. To maintain backward compatibility, an alias was kept:
If you installed videojs-contrib-hls via npm:
// Dirty hack – do not use in production videojs.log.warn = function() {};
This warning appears because Video.js has updated its internal naming convention for the HTTP Live Streaming engine. The hls property on the tech object is being phased out in favor of vhs (Video.js HTTP Streaming). If you installed videojs-contrib-hls via npm: // Dirty
videojs warn player.tech--.hls is deprecated. use player.tech--.vhs instead
If you're a web developer working with to stream HLS (HTTP Live Streaming) content, you may have encountered the following warning in your browser's console:
is a streaming protocol developed by Apple. It’s widely used for delivering video content over the web, especially for live streams, VOD (Video on Demand), and adaptive bitrate streaming. HLS breaks video into small chunks (.ts or .m4s files) and uses a manifest file (.m3u8) to describe the available streams.
