[Cin] vaapi vs appimage, kdenlive way

[Phyllis Smith]

As far as I know, the goal is for the new released AppImages to work on
other computers that have VAAPI and VDPAU hardware graphics capabilities
even if at different levels of the operating system than the computer where
the AppImage was created.

But so far, I have not been able to either get a good test or any good
results.  (BTW credit goes to Andrew for suggestion to try this + all of
the advice I need to do so).

Latest test results:
- created AppImage on older Fedora version 31 which is HP/Intel chip where
both VAAPI and VDPAU work.

- main.C currently contains the 2 lines shown below (have not tested
Andrew's newest suggestion yet)

- on the AMD laptop running Fedora 32 VAAPI gives the following errors just
doing a single load:

HW device init failed, using SW decode.

- a single load of VDPAU works (but I seem to have in my brain, that this
gets simulated somehow)

More experimentation is coming with some variations.
