Hello Gary, 
What is the reason why you need libcrystalhd there ?
Which software requires it ?

The MythTV package (using its embedded FFmpeg support) can optionally utilize the crystalhd hardware (if available on the platform).  It is admittedly old hardware at this point, and used by only a few people (and I am not one of them), so it would not bother me personally If you choose to drop crystalhd for epel and fedora moving forward.

Indeed mythtv uses this libcrystalhd, so it should be possible to enable it for el8 also.
Requesting branch. (please apply to src.fedoraproject.org acl to co-maintain).

fwiw, kodi also builds with/uses libcrystalhd (and kodi is likely a popular package which I would guess someone will want to see built (over at rpmfusion) at some point).
