Demos of AV1 + DRM?

benwaggoner · 19th June 2020, 03:21

Has anyone made a demo or test content of AV1 with DRM? Like a DASH adaption set with Widevine Level 1 & 3?

I understand how it should work, but can't seem to find anyone who has done or seen a proof of concept.

Hmm. Looks like Shaka packager should support this https://github.com/google/shaka-pack...3e89786a73a1b0

Should be no different from packaging any other codec in fMP4 with either CTR or CBCS (hopefully the latter). I've never tried tho

Yeah. I don't see much evidence that anyone has tried DASH adaptive streaming with AV1 + DRM yet.

VP9 also uses so called profile 4 for DRM.

Any context on that? I'm not aware of any reason why the encoding settings would need to change to be compatible with DRM?

The encoding settings shouldn't need to change, correct.

I was (15 months ago!) looking for a test package to test AV1 DASH with DRM on different devices.
