Re: Custom and extending CDM to support other DRM systems

Glenn,

thanks a lot for you answer. Though I would prefer to hear it from the
editors, and to provide possibly any direct contact to start a
discussion which may not be part of this mailing list, but EME does

of them.

Thanks in advance for any persons willing to discuss it further, or to
create a different discussion thread to talk about it.
