[Cin] Tested vaapi hwaccel presets

[Andrea paz]

I tested vaapi presets with the compile of the new CinGG release.
Previously vaapi was not working for me in either encoding or decoding. Now
I have no errors or warnings.

I used the Big Buck Bunny 1080p and 30 fps file with h264 codec. With some
presets the rendering fails with the following errors in the terminal:

- av1_vaapi_10b420.mp4

Other presets work more or less well:

- h264.mp4 --> 78 fps
- h264_vaapi.mp4 --> 118 fps
- h264_vaapi_8b420.mp4 --> 80 fps
- hevc_vaapi.mp4 --> 81 fps
- hevc_vaapi_8b420.mp4 --> 110 fps


IMPORTANT: These tests are not indicative, as I always have new problems
with my Radeon RX 5700 XT with every driver update.

PS: Compilation time got a lot longer, is it because of the new patches?
PPS: I have not followed the various threads very well and so I do not know
the conclusions you have reached....
