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.

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
