While I do not think it is an alternative in itself, and therefore orthogonal to this discussion, I would like to see any draft resulting from this also containing a set of requirements leading to work that makes any hardware based codec available to the application via the browser. I agree any APIs that already exist in this area do need more work and that work is not the work of rtcweb (and it is also not my area of expertise), but we seem to be drifting round in circles trying to deal with rights issues on downloaded codecs, and ignoring the use of codecs that may already be installed on the device for which the rights have already been paid.
