Videojs Warn Player.tech--.hls Is Deprecated. Use Player.tech--.vhs Instead May 2026

Title: System Update Required: Video Player Technology

Body: Our video player system has issued a deprecation warning regarding the hls component. This indicates that a specific piece of code used to manage video streaming is outdated and will eventually stop working.

To ensure the video player remains stable and compatible with future updates, our development team needs to update the code references from player.tech_.hls to player.tech_.vhs. This is a routine maintenance task that ensures long-term reliability and performance.

Here’s a short, interesting story built around that technical warning.

Title: The Ghost in the Stream

Maya was a video engineer who prided herself on clean code and silent consoles. No red flags. No warnings. Her latest project was a 24/7 live stream for a retro game marathon called Pixel Purgatory.

The stream launched flawlessly. Thousands of viewers tuned in to watch speedruns of obscure 1990s platformers. But at 3:17 AM, a single warning flickered in her browser’s developer console:

VIDEOJS WARN: player.tech--.hls is deprecated. Use player.tech--.vhs instead.

Maya almost ignored it. Deprecated, not broken, she thought. It can wait until morning.

But the stream started glitching. Not normal buffering—weird glitches. Frame repeats. Subtitles showing scrambled text like SEGMENT_3.ts NOT FOUND BUT ALSO FOUND. The chat filled with spam: “Did the stream just lag into another timeline?”

Then a viewer named hls_ghost sent a single message: “You’re still using the old HLS tech. I’ve been waiting for someone to notice.”

Maya’s heart thumped. She opened the network tab. The manifest file was fine. But every few seconds, a request to a non-existent segment path appeared: /legacy/hls/player.tech--.hls/deprecated.js

She had never seen anything like it. It was as if the player was talking to a dead version of itself.

Fingers flying, she changed the player configuration: Title: System Update Required: Video Player Technology Body:

// old
techOrder: ['html5', 'hls']
// new
techOrder: ['html5', 'vhs']

She added the explicit VHS setup:

html5: 
  vhs: 
    overrideNative: true

The moment she deployed, the console cleared. The glitches stopped. And hls_ghost went silent.

At 3:33 AM, the stream returned to perfect clarity. A final message from the ghost appeared in chat—not as a user, but as a system notice:

[System] player.tech--.vhs initialized. Legacy handler laid to rest.

Maya sipped her cold coffee and whispered, “Goodnight, old tech.”

From that day on, every new project started with VHS—not because the docs demanded it, but because she knew what slept in the deprecated shadows.

The warning videojs warn player.tech().hls is deprecated. use player.tech().vhs instead occurs because Video.js transitioned its underlying streaming engine from a dedicated HLS library to the more versatile Video.js HTTP Streaming (VHS) engine. Why the Change?

Protocol Neutrality: While the original engine (videojs-contrib-hls) was built specifically for HLS, developers realized the same core logic could handle multiple formats.

VHS Successor: VHS is the official successor that supports both HLS and DASH content within a single, unified codebase.

Better Integration: VHS has been bundled into Video.js by default since version 7.0, providing a more consistent experience across browsers by overriding native HLS playback where necessary. How to Fix the Warning

To resolve the deprecation warning, update your code to reference the vhs property instead of hls. Title: The Ghost in the Stream Maya was

Accessing Runtime Properties:If you previously accessed properties like playlists or representations through player.tech().hls, switch to vhs: javascript

// Old (Deprecated) var hls = player.tech().hls; // New (Recommended) var vhs = player.tech().vhs; Use code with caution. Copied to clipboard

Updating Initialization Options:When setting up your player, update your options object to use the vhs key: javascript

// Old (Deprecated) var player = videojs('my-video', hls: overrideNative: true ); // New (Recommended) var player = videojs('my-video', vhs: overrideNative: true ); Use code with caution. Copied to clipboard

Handling "Undefined" Errors:The vhs object is only attached to the tech when an HLS or DASH stream is actively in use. Ensure your media has loaded or use the player's ready callback before attempting to access it. videojs-http-streaming (VHS) - GitHub

Deprecation Warning: Using player.tech_.hls is Deprecated, Please Use player.tech_.vhs Instead

Introduction

Video.js is a popular JavaScript library used for video and audio playback on the web. Recently, a deprecation warning has been raised regarding the use of player.tech_.hls in Video.js. This report aims to provide an overview of the issue, its implications, and recommendations for mitigation.

Background

HLS (HTTP Live Streaming) is a widely used protocol for live and on-demand video streaming. In Video.js, HLS playback is facilitated through the hls tech. However, with the introduction of VHS (Video.js HLS Shim), a more efficient and feature-rich solution for HLS playback, the hls tech has been marked as deprecated.

The Deprecation Warning

When using Video.js with the hls tech, a warning is logged to the console:

WARN: player.tech_.hls is deprecated. Use player.tech_.vhs instead.

This warning indicates that the player.tech_.hls property is no longer recommended and will be removed in future versions of Video.js. VIDEOJS WARN: player

Implications

Using the deprecated player.tech_.hls property may lead to:

Recommendations

To ensure continued support and compatibility with future versions of Video.js:

Example Code

Here's an example of how to initialize a Video.js player using the VHS tech:

const player = videojs('my-player', 
  techOrder: ['vhs'],
  sources: [
    src: 'https://example.com/hls-stream.m3u8',
    type: 'application/x-mpegURL',
  ],
);

Conclusion

The deprecation of player.tech_.hls in Video.js is a necessary step towards maintaining a stable and feature-rich playback solution. By migrating to player.tech_.vhs, you can ensure continued support, compatibility, and access to the latest features and bug fixes. We recommend updating your code to use the VHS tech to avoid potential issues and ensure a seamless playback experience.

The warning indicates you're using the deprecated player.tech_.hls property. In modern Video.js versions (especially those using http-streaming or videojs-contrib-vhs), the correct property is player.tech_.vhs.

The Video.js core team issues deprecation warnings for two primary reasons:

In short: The warning does not mean tech_.hls is gone; it means it will be removed in a future major version.
