Spurred on by the discussion and
                with additional information supplied by Sam, mods have
                been by GG and checked into GIT that take further
                advantage of the GPU capabilities of modern graphics
                boards and more recent device drivers for those boards.
              


                

              
This
                  is very preliminary at this point.  We have
                  tested with Nvidia, Radeon, and Broadwell graphics
                  board on AMD and Intel computers and ran at least 30
                  tests.  In these tests, if you run "top" from another
                  window, we could see the CPU usage with this API go
                  down by 2 to 10 times lower,

              


                

              
How
                  to use IF you have the appropriate graphics board and
                  the proper libraries installed:

              


                

              
1)
                  You need to have libva-dev installed on Intel
                  processors;

              
2)
                  or you need to have libvdpau-dev installed on AMD
                  processors.

                

              
3)
                  Verify Settings->Preferences, Playback, Video
                  Driver is set to X11 (NOT X11-OpenGL).

                

              
4)
                  Before starting CinelerraGG, set an environment
                  variable -- because this is so new and we do not have
                  the capability of testing across all hardware and all
                  operating system distros, we used an environment
                  variable in order to make it easily reversible by the
                  user.  To run in the installed directory:

              


                

              
      
                  CIN_HW_DEV=vaapi ./cin   (for Intel)

              
 
                  Or CIN_HW_DEV=vdpau ./cin

                

            

          

        

      

    

    


    

    
Dreams still come true. Thank you very much for this improvement.

    

    I tested it the same way, but I get the error message.

    

    Decoder h264 does not support device type vaapi.

    HW device init failed, using SW decode.

file:/home/spc/cin-test/aerial-shot-of-las-vegas-sprawl-daytime_w18wevlbr__D.mp4

     err: Success

    

    Under OpenSuse I installed the following package.

    zypper install libva-devel-2.4.0-lp150.114.1.x86_64.rpm

    

    In the Cin settings I have set it to X11. However, I have installed
    the proprietary drivers, do I need to change this?

    

    
Thanks again for this implementation.

    
Sam
