VAAPI does not work with Wayland session

[jasauders]

Using Bluecherry Client 2.2.6 with Ubuntu 17.10 (pre-release) in the Wayland session, Bluecherry does not yield the 'va' entry in the corner of the camera titles to signify that VAAPI (hardware acceleration) is active. Bluecherry Client, so far, seemingly works in all other areas within the Wayland session excluding the hardware acceleration piece.

Ubuntu 17.10 will be released in a few weeks from the time of this writing and it has been noted in pre-release statements that 17.10 will default to Wayland by default along with consecutive releases (18.04, etc) into the future.

In an effort to re-organize much of the chat room conversation on this topic back to this issue, here are some updates for easier reference.

The below is taken from a system with an i5-7200u processor on a fresh install of Ubuntu 17.10 with v2.2.6 of the Bluecherry client. This is a Wayland session in the Gnome desktop environment as provided by 17.10.
