Hello. I am trying to get Quicksync to work on Centos 7.2 following EXACTLY each step but nowadays the ISO downloaded from server contains the libdrm version 2.4.67 and the Wowza package contains the 2.4.66. I’v tried to downgrade the installed libdrm without success.

Please, help me. I am getting crazy with this :mad:. :-p

Regards,

Radiov

SOLVED: after downgrade the library I had changed UEFI Boot Security to Other OS (Asus Motherboard) and everything was ok.
