iOS 27 video playback

What is the system language on your device? The problem seems to be related to Apple Intelligence which can automatically translate the subtitles. But it doesn't matter whether this feature is activated or not. Try changing the language to english in the Siri settings or some language that does not match your system language. A text will appear explaining that Apple Intelligence is disabled now and the icon changes to the old Siri icon. Try again to play the video with english subtitles. I assume it will work.

I reported this to apple, but it still does not work on iPad OS 27.2 on my device.

Do the videos you are trying to play include subtitles?

I experience problems playing videos with english subtitles (tracks with srclang="en") on iPadOS 27 even though they are not visible. Check in the lower right corner of the video player if you can choose subtitles and compare to videos not having subtitles.

I'm experiencing the same issue, and it is still not resolved as of October 26, 2026.

Affected devices:

• iPhone 17 Pro — iOS 27.0.1 (Build 24A446)
• iPad Pro M5 — iPadOS 27.0.1 (Build 24A446)

Videos on my university's online learning platform fail to play in both Safari and Chrome. The player reports MEDIA_ERR_SRC_NOT_SUPPORTED (Error Code 4).

I investigated the issue using Safari Web Inspector and found something interesting.

The problem appears to be related to English subtitle tracks (srclang="en").

• Videos fail to play when an English WebVTT subtitle track is present.
• Removing the English subtitle track before initializing the player allows the original video to play normally.
• Changing only srclang="en" to srclang="ko" also allows playback, without modifying the video or subtitle files.
• I reproduced the same behavior using the HTML5 <video> and <track> example on MDN, completely independently of my university's website and its Video.js player.

My older iPhone running iOS 18.6.2 plays the videos normally. My MacBook and other people's iPhones also work.

I have already tried restarting the devices, resetting Safari feature flags, disabling extensions, changing subtitle and language preferences, and using Private Browsing. None of these resolved the issue.

I have submitted a report through Apple's Safari Product Feedback form.

Is anyone else still experiencing this issue? Has anyone found a permanent fix?

It seems to be related to how WebKit handles English WebVTT subtitle tracks on certain iOS/iPadOS 27 devices.

I'm having the same issue. I reached out to the website It (it's through a univ) and they were not able to figure out why even after looking at the website logs.

We are having the same issue on our LMS using Articulate Rise content with subtitles enabled shows nothing but a blank white space where the video is supposed to load. But its not happening to everyone, we are trying to identify what is different about those devices (all on iOS 27.0.1) that are having trouble while others are not, there must be a setting possibly? So we may just have to remove the subtitles altogether and republish the whole course.

I visit a favorite website on Safari to use their workout videos. The videos play fine on my iMac running macOS 27.

However, the same videos do NOT play on my iPhone with iOS 27, nor on my iPad with iPadOS 27.

I’m flummoxed about how to fix this.

The issue I’m having is that embedded video doesn’t play since installing iOS 27 on my iPhone (16e). Displays a continuous, rotating white circle instead. Happens on video embedded in web pages and in apps. Have tried a couple of different browsers (chrome, edge) and same issue. Have ensured running the latest versions of browsers and apps.

Problem is on both Safari and Chrome. Not all websites are affected but most I’ve tried are. After clicking the video start the screen goes grey. Same issue on my iPhone 17 pro and my iPad Pro. I have emptied the website data, made sure JavaScript is on, and force restarted. Extremely frustrating. I have training videos I’m required to watch for my employment that I’m unable to.

Today the videos from the exercise site that wouldn’t work before, started to play on my iPad, and my iPhone. They continue to play well on my iMac.

I didn’t change anything that I know of, but perhaps Apple Support, which I enlisted to help solve my playback issues, succeeded in changing something behind the scenes.

I hope others are having success as well.

Depends on what issues you are having.

Is this in an app?

Website video?

Downloaded video?

More information with details about what is happening would help greatly.

If you have any insights on how to fix this, Johnathan, I would be very grateful to hear them.
