HW decoding is not working, although it works with other H.264 sites, like YouTube with a proper extension.

Same behavior here in a site, which can be tested by any user, without any subscriptions:

It seems that HW acceleration does not work with encrypted videos.

A beer for a solution. ;)

Does the linked bug mean that this is a common problem; graphics drivers do not support encrypted video encoding?

BTW, I am using VDPAU.

Yes.

Have to say, that HW-acceleration works with encrypted videos with recent Firefox and amdgpu/va-api.
