Steps to reproduce

See the attached sample content not_working.mp4 which is encrypted with:

  key_id: d4ce25052c03e1814abe8a3df2c6910f 
  key:    12a4b8e8e48340fcbb3ccc2b41e40dc5

An error with code 4,80004005 is returned when trying to play the content in Edge (using with an appropriate license server setup). This sample content has sinf box put before avcC box:


If I swap the the order of sinf and avcC, then it plays successfully, see working.mp4.

I don’t see a requirement anywhere in the spec that sinf should be put before avcC box. Edge should not reject the streams with this.

Expected behavior: both streams should work in Edge, as in Chrome and Firefox.

  • Hi,

    Do you have a license server I can use?

    Thank you for the help,


  • I will run the repro using our playready test servers on Azure.

  • Can confirm I’m experiencing the issue as well.
    Other people that also reported the same issue on Shaka are able to reproduce the issue and have narrowed the issue to DRM content with clear lead. Removing the clear lead solves the issue.

  • I can still reproduce this on Edge/16.16299. Can anyone from Microsoft provide any updates on this?

  • Apologies for the lack of communication on our end. This bug got resolved as a duplicate of another internal bug that got bounced around and eventually landed on me. I checked in a fix last week which should be available in insider builds within the next couple weeks.
