I cannot make a clearkeydrm embedded key:value working. Should this fix be available in a release or nightly build?

ClearkeyDRM(embedded key:value license key), not working
https://m.dtv.fi/dash/index_clearkey2b.html?video=21
uses https://reference.dashif.org/dash.js/nightly/dist/dash.all.debug.js script.

ClearkeyDRM(laurl php script license key), works ok
https://m.dtv.fi/dash/index_clearkey2.html?video=21
uses https://cdn.dashjs.org/latest/dash.all.debug.js script.

NoDRM test(free), works ok
https://m.dtv.fi/dash/index_clearkey2.html?video=2f

Hi @Murmur ,

I'm able to play your first stream by adding this line :

if (initData.constructor === Uint8Array) { in function createKeySession of ProtectionModel_21Jan2015 in order to not take into account the last encrypted event with a strange initData value.
So, it means the fix just above is not efficient enough.

Have you made any change to your protected streams that can explain this behavior?

@nicosang No I have not updated the content(init.mp4, seg.m4s, manifest) it is what it's been all this time. I have never been able to dashjs playback ClearkeyDRM with an embedded key:value license key.

Both tests pages use this same manifest and video files.

ok, I understand...So, would you like, please, register a new issue with all your sample streams?
This PR had the regression tag that it is not the case of your problem....In a second time, I will provide a PR with my small fix described above.

Thanks,
Nico
