VPP: the output will always same when set different denoise level.

[feiwan1]

By using libyami/gstreamer-vaapi, and set different denoise value, the output always bitmatch.

gstreamer-vaapi issue link:
https://bugzilla.gnome.org/show_bug.cgi?id=796635

libyami issue link:
intel/libyami#861

And we use gstreamer-vaapi test on iHd drvier, it looks good.

same issue is observed with ffmpeg-vaapi, too.

seems like the same issue I'm finding. I'm using ffmpeg with a docker image, here's the commit to the implementation

I messaged @mypopydev about this issue. I noticed if I go over the specified limits it gives out a warning, so it tells me the feature is active in this build, however at any setting up until 64 there is no change in the image or the output file size

@xhaihao can you take a look at this issue?

Bumping this issue. I have also noticed that the denoise filter doesn't seem to have any effect with this driver on multiple platforms with Gen9 graphics (maybe others).
