when the system language is something other than English the Shaka player attempts to load the English audio track as well as the system language audio track if it exists.

Are you using the demo app or your own custom app?
our own

If custom app, can you reproduce the issue using our demo app?
YES

What browser and OS are you using?
Version 91.0.4472.101 (Build officiel) (arm64) - chrome
Safari Version 14.1.1 (16611.2.7.1.4)
iOS 14.6 - Big Sur 11.4

For embedded devices (smart TVs, etc.), what model and firmware version are you using?

What are the manifest and license server URIs?

What configuration are you using? What is the output of player.getConfiguration()?

What did you do?

Tried to play the video on safari on both my iPhone and my macbook

What did you expect to happen?
I was expecting it to play the video

What actually happened?

We figured out that once my device system is in English, I am able to play the content without any problem. Except on google Chrome on my iPhone.

It appears as though when the system language is something other than English the Shaka player attempts to load the English audio track as well as the system language audio track if it exists.

Is it the best option for us to attempt to “fake” the player out to think that the system language is English so that it doesn’t attempt to load other language files at the same time? If yes, how can we do it, please?

[baseballbrad3]

This issue seems to be the same problem as I was going to report, so I'll post my message which might have some more details.

Have you read the FAQ and checked for duplicate open issues?

Yes

What version of Shaka Player are you using?

3.1.1

Can you reproduce the issue with our latest release version?

Yes

Can you reproduce the issue with the latest code from master?

Maybe? I get a 6010 error immediately and it doesn't get far enough to make a license request. The issue I'm seeing does get far enough to make licenses requests.

Are you using the demo app or your own custom app?

Custom

If custom app, can you reproduce the issue using our demo app?

There don't appear to be any FairPlay examples in the demo, and we transform the license request and are unable to use the Custom Content feature of the demo app.

What browser and OS are you using?

• Safari 14.1.1 on macOS Catalina 10.15.7 with the OS language set to French
• Safari 12.1.2 on an iPhone 5s iOS 12.5.3 with the iOS language set to French

For embedded devices (smart TVs, etc.), what model and firmware version are you using?

N/A

What are the manifest and license server URIs?

We'll need to email this, if it's needed.

What configuration are you using? What is the output of player.getConfiguration()?

What did you do?

1. Set the OS language to French
2. Close Safari to ensure the new language is applied
3. Reopen Safari to our test page
4. Try to play a FairPlay DRM'ed HLS file that contains multiple audio track languages, including a French audio track

What did you expect to happen?

Expected the content to start playback reliably while the OS language is set to French. We do see reliable playback when the OS language is set to English and with native .

What actually happened?

We see sporadic behavior. Sometimes, the content plays with no issues. Other times, the title fails to start with a 3016 error. It varies pretty wildly too. If I make 10 attempts, they could all play successfully. I could make another 10 attempts and it might play successfully only once.

[Error] Error code – 3016 – "object" – {severity: 2, category: 3, code: 3016, …}

With the same content and license server, we don't have playback issues when we omit the Shaka Player and use the vanilla HTML5 player. We can provide a sample if necessary.

We also don't have the issue when the OS language is English and we use Shaka Player, again, with the same content and license server. This could be due to our HLS manifest declaring English as the default track.

I do see a difference in the shaka logs between successful and unsuccessful playback attempts.

If you throw these two logs into a diff tool, it's easier to see what happens in the failed playback attempt. It appears that the webkitneedkey event starts getting called repeatedly, and is never satisfied in that failed playback attempt.

I tried setting my iPhone's language to French and playing the multi-lingual track on our demo player, in Google Chrome, and it seemed to play without issue. I heard Picard talking in French, anyway.
When you say that it's loading the English track also, do you mean it's loading the English track and not using it? Or it's playing both audio tracks at once?

Either way, I don't think this is likely to be a problem with us in particular. As you can see from the compatibility chart on our GitHub front page, for iOS, we only support Native playback. One of the main APIs we rely on is still only partially supported on iOS, so we just forward attempts to play assets to the builtin browser playback.

The problem appears on Safari only, everything is working on Chrome.

What do you suggest in order to move forward?

Thank you,

[joeyparrish]

The problem appears on Safari only, everything is working on Chrome.

You did mention Chrome in your report:

What browser and OS are you using?
Version 91.0.4472.101 (Build officiel) (arm64) - chrome
Safari Version 14.1.1 (16611.2.7.1.4)
iOS 14.6 - Big Sur 11.4

If it only fails in Safari, you should have been more clear. @theodab, can you please try in iOS Safari? I don't believe any of the rest of us have iOS at home.

[baseballbrad3]

If I were to guess, the "arm64" version of Chrome is the iOS version, which is essentially Safari under the hood. Perhaps the Chrome that works was a desktop version?

Also, I'd like to reiterate that when I've observed the issue, it was with FairPlay content. I couldn't reproduce this with non-DRM content.

[theodab]

Ok, I tried this in iOS Safari too, and I did not notice any outwardly anomalous behavior there either. French audio was playing, as expected. I did not see any errors, either.
When I used the Safari Web Inspector to view the downloads, I did see that we load the English audio manifest and init segment, but we load no actual English audio data. Is that what you meant?
I am not 100% sure, but I think that might happen when we are fetching the init segment in order to determine the start time of the stream. This is something that we have to do for HLS because that information is not present in the HLS manifest structure, if I recall.
Are you using native HLS playback on Safari? You did not provide the output of player.getConfiguration(). If you ARE using native playback, the problem is probably something else.

@baseballbrad3, are you sure that your issue is related to this? The original bug report did not mention seeing any errors, nor did it specify Fairplay.

I'm working on a sample I can upload where you can see the issue. I'll post it later. I have a sample where the same content fails in Safari with Shaka, but works in a html 5 video tag with just raw javascript. both use fairplay.

[abdevnet]

Archive.zip
I've attached my sample. You will need to host in a simple web server. The index.html page uses Shaka and it consistently gives me a 3016 error when my system language is set to French. The index2.html page just uses a video tag with raw javascript and it works for me when my language is French. The video is Tears of Steel and in our Azure cloud. This video doesn't natively have a french audio track. I took the English track and copied it, renamed it to fr-FR and made the necessary manifest updates. So when you do switch to French you will still hear English. Hopefully you are able to reproduce what I'm seeing.

[baseballbrad3]

@theodab, yeah, I'm pretty certain my issue is the same as the original post. The company I work for is providing the content to @clotairemarmignon, which is FairPlay protected. @abdevnet has a sample of this content in the previous comment.

[joeyparrish]

We will try to repro with the content you sent. Thanks.
