DRM Video Playback Issues in Safari

Some learners may experience playback issues while watching DRM-protected videos in Safari. Common issues include License Failed, Content Play Failed, video loading continuously, black screen, or the video failing to start.

Safari handles DRM-protected content differently from Chrome and Edge, so certain playback issues may be related to Safari settings, macOS/iOS configuration, website permissions, or protected-content restrictions.

Common DRM Playback Issues
  • License Failed
  • Content Play Failed
  • Video stuck on loading
  • Video does not start
  • Video stops during playback
  • Black screen during video playback
  • DRM or protected-content errors
  • Video works in another browser but not Safari
Troubleshooting Steps

1. Update Safari and the Operating System

Safari is updated together with the operating system.

On macOS:

  1. Open System Settings.
  2. Go to General → Software Update.
  3. Install any available macOS updates.
  4. Restart the Mac.
  5. Open Safari and try playing the video again.

On iPhone/iPad:

  1. Open Settings.
  2. Go to General → Software Update.
  3. Install any available iOS/iPadOS updates.
  4. Restart the device.
  5. Try playing the video again.

2. Check Safari Website Settings

Make sure the learning platform is not being blocked by Safari settings.

Check the website settings for the affected learning platform and make sure that JavaScript, cookies, and required website permissions are not being blocked.

3. Disable Content Blockers

Content blockers or Safari extensions can sometimes interfere with DRM-protected video playback.

Temporarily disable:

  • Ad blockers
  • Content blockers
  • Privacy extensions
  • Download-related extensions
  • Other Safari extensions

Then reload the learning platform and try playing the video again.

4. Clear Safari Website Data

If the issue continues, clear the website data for the affected learning platform and log in again.

On macOS:

Go to:

Safari → Settings → Privacy → Manage Website Data

Search for the learning platform's domain, remove its stored website data, restart Safari, and try again.

5. Try a Private Window

Open a new Private Browsing window in Safari and try playing the same DRM-protected video.

If the video works in Private Browsing, cached website data, cookies, extensions, or Safari settings may be contributing to the issue.

6. Check the Internet Connection

Make sure the device has a stable internet connection while playing DRM-protected content.

If possible, try another network and check whether the issue persists.

7. Restart the Device

Restart the Mac, iPhone, or iPad and try playing the DRM-protected video again.

A restart can resolve temporary browser, system, or media-component issues.

8. Test Another Supported Browser or Device

Try playing the same video on another supported browser or device.

If the video works elsewhere, the issue may be specific to Safari, the device configuration, website settings, or the DRM environment.

Common FAQs

Why am I seeing a "License Failed" error in Safari?

A License Failed error means Safari was unable to successfully obtain or process the DRM license required to play the protected video. The issue may be related to Safari settings, website permissions, stored website data, network connectivity, or the device's DRM environment.

Why is my DRM video not playing in Safari?

DRM playback can fail if Safari or the operating system is outdated, website permissions are restricted, content blockers interfere with playback, stored website data is corrupted, or the device cannot successfully process the DRM license.

Does Safari support DRM-protected videos?

Yes. Safari supports DRM-protected video playback using Apple's protected media technologies. The exact DRM capabilities depend on the Safari version, operating system, device, and content configuration.

Why is my DRM video stuck on loading in Safari?

The video may remain stuck on loading if Safari cannot obtain the required DRM license, if website data or permissions are causing an issue, or if there is a network connectivity problem.

Why do I see a black screen while playing a DRM video in Safari?

A black screen can occur when Safari or the device is unable to correctly process the protected video content. Updating the operating system, disabling content blockers, clearing website data, and restarting the device may help.

Can Safari extensions cause DRM playback issues?

Yes. Content blockers, ad blockers, privacy extensions, and other Safari extensions can interfere with website functionality and DRM-protected content. Temporarily disabling these extensions can help identify the cause.

Why does the video work in Chrome or Edge but not Safari?

If the video works in another supported browser but not Safari, the issue may be specific to Safari settings, website permissions, stored website data, Safari extensions, or the device's DRM environment.

Why does the video work in a Private Browsing window but not normal Safari?

If the video works in Private Browsing, cached website data, cookies, extensions, or other Safari settings in the normal browsing session may be causing the issue.

Will clearing Safari website data fix a DRM License Failed error?

Clearing website data can resolve some DRM playback issues caused by corrupted or outdated cookies and cached data. However, it may not resolve issues caused by the DRM license service, network connectivity, device configuration, or other system-level problems.

Can I use Safari on an iPhone or iPad to watch DRM-protected videos?

Yes. Safari is the recommended browser for DRM-protected video playback on iPhone and iPad. Make sure the device is updated to the latest available iOS or iPadOS version.

What information should I provide to support if the DRM issue continues?

Please provide:

  • Screenshot of the error
  • Exact error message
  • Name of the affected video
  • Safari version
  • macOS, iOS, or iPadOS version
  • Device model
  • Whether other DRM videos are affected
  • Whether the video works in another supported browser or device
  • Whether the issue occurs in a Private Browsing window
  • Whether disabling content blockers or extensions changes the behavior

This information helps the support team determine whether the issue is related to Safari, the device, network connectivity, or the DRM license configuration.
