I went to RPMfind, downloaded pepperflash rpm, installed and now Opera 38.X can play flash content again.
Now Opera sees the "flash" plugin and I can enable that. www.cvinetwork.com allows me to see streaming media again. Again, I am running Mageia 5.x and Opera 38.X However, the wretched Chromium browser still gives me flash player missing error message. I suspect pepperflashplayer.so is not in the proper location.
Its been a long afternoon.
