"Media failed to decode error" after a few playbacks on macOS

[lepinese]

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

If the problem is related to FairPlay, have you read the tutorial?

Yes

What version of Shaka Player are you using?

4.9.8

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

If custom app, can you reproduce the issue using our demo app?
Haven't been able to make the custom demo app work at all, the License call fails with a HTTP Status 412 – Precondition Failed.
But the Big Buck Bunny (FairPlay) demo works fine.

What browser and OS are you using?
Safari : 17.2.1
macOS : Sonoma 14.2.1

What are the manifest and license server URIs?

We are using DRMToday

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

What did you do?

The first few playbacks of the media work normally but then at some point (could be 1, 10 or more playbacks) we keep getting the "Media failed to decode" error and it stops working.

I found this issue which looks similar but was closed to inactivity : #4852

Just like this issue, when restarting Safari it works again.

When it fails, our license calls are still working normally. When looking at the debug console there doesn't seem to be any relevant information about what's going wrong.

Here's a bit of code :

this.player.getNetworkingEngine().registerRequestFilter(function(type, request) {
    if (type === shaka.net.NetworkingEngine.RequestType.LICENSE) {
        request.headers['X-Dt-Auth-Token'] = fairplayAuthToken;
    }
});
this.player.getNetworkingEngine().registerResponseFilter(function(type, response) {
    if (type === shaka.net.NetworkingEngine.RequestType.LICENSE) {
        const responseText = shaka.util.StringUtils.fromUTF8(response.data);
        response.data = shaka.util.Uint8ArrayUtils.fromBase64(responseText).buffer;
    }
});
this.player.configure({
    drm: servers: {
        'com.apple.fps': fairplayLicenseUrl)
    },
    advanced: {
        'com.apple.fps': {
            serverCertificate: new Uint8Array(fairplayCertificate)
        }
    manifest: {
        hls: {
            allowLowLatencyByteRangeOptimization: true
        }
    }
});

What did you expect to happen?
The media to work all the time

Is there any movement on this ticket? I've sent through info on #7664

[avelad]

I have been able to reproduce the bug, but I have not had time to work on it.

[ProtoScott]

@avelad Have you had a chance to look further into the issue? Is there anything we can do to help?

[koenoe]

We've had this issue too (and we use DRMToday as well), but can't reproduce anymore in Sequoia. And for what it's worth, we could reproduce this in Sonoma in other players as well (Prestoplay and Bitmovin).

[avelad]

@ProtoScott Do you reproduce the error on macOS Sequoia?

This issue has not been resolved @shaka-bot reopen

[avelad]

@lepinese Do you reproduce the error on macOS Sequoia?

[lepinese]

@avelad I will be testing it today or tomorrow, I will let you know the result!

[lepinese]

@avelad I haven't been able to reproduce the issue on Sequoia either although this time I get an error when trying to load the media with Safari's Inspector open.

It says :
Web Inspector blocked ** the manifest *** from loading

Unhandled Promise Rejection: shaka.util.Error {
  "severity": 2,
  "category": 3,
  "code": 3016,
  "data": [
    4,
    null,
    ""
  ],
  "handled": false,
  "message": "Shaka Error 3016",
  "stack": "T@\nho@\n@\ne@"
}

It's worrisome but doesn't seem that big of a deal since most users won't open their Inspector.

As for the original issue I'm relieved it's fixed with Mac's update but this means users who haven't updated their OS will still hit the error. I'm not really sure what's the next step.

[avelad]

Well, it seems to be a problem with the Safari+macOS combination, I don't know if we can do something in Shaka... @tykus160 what do you think?

[tykus160]

Clearly it has been fixed by Apple, I don't think we have any way to prevent this from happening on older versions. I can only suggest to try to experiment with streaming.useNativeHlsForFairPlay = false as I think DRMtoday supports it.
