Environment

• [X] The MPD passes the DASH-IF Conformance Tool on https://conformance.dashif.org/
• [X] The stream has correct Access-Control-Allow-Origin headers (CORS)
• [X] There are no network errors such as 404s in the browser console when trying to play the stream
• [X] The issue observed is not mentioned on https://github.com/Dash-Industry-Forum/dash.js/wiki/FAQ
• [X] The issue occurs in the latest reference client on http://reference.dashif.org/dash.js/ and not just on my page

• Dash.js version: Latest product
• Browser name/version: Chrome latest version

Steps to reproduce

1. Please provide clear steps to reproduce your problem We observe the below error sometimes while playing back the encrypted DASH streams (ClearKey encryption is used) on https://reference.dashif.org/dash.js/v4.4.0/samples/dash-if-reference-player/index.html player. After refreshing the player and retrying the playback, error disappears.

2. If the bug is intermittent, give a rough frequency if possible Mostly every playback the error pops up, but after refreshing the error disappears.

Observed behavior

Error seems to pop up unnecessarily.

Expected behavior

The error should not pop up as the encryption workflow is working after refresh.

Can you reproduce the problem with one of the example streams in the reference client? Or only your own stream?

[Aliendreamer]

we have a similiar experience, from last week. Depoying a new version of our streaming application, But the problem seems only on Samsung tizen platform mainly with little exceptions for Lg webos platform, I will try to check if we can provide streams. We are currently on dash 4.2.0

[VyshnaviUmesh]

We are working with internal streams right now, so unable to provide the streams at this moment. Once we are able to publish the streams and software, we could share the public URL. Thanks.

For Clearkey please check the current development branch or the nightly version of the player. There was a fix that might be related to this: https://github.com/Dash-Industry-Forum/dash.js/pull/3939

[VyshnaviUmesh]

We have been using the current dev branch and still observe the same issue. Just tested with the nightly version of the player and it has the same issue.

We can't shere streams too at least not drm protect. but I think we found he main source for us at least. In dash settings: protection: { keepProtectionMediaKeys: true, }, setting this seems to trigger the problem with 113, we tried this setting to mitigate 112 drm errors. And as I said before we are using dash 4.2.0 we havent tried 4.4
