Subject: vaapipostproc: Use level value for skin-tone-enhancement filter.
X-Git-Tag: 1.19.3~503^2~386
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4c87644914139c22542d0f485d050cca486188a5;p=platform%2Fupstream%2Fgstreamer.git

vaapipostproc: Use level value for skin-tone-enhancement filter.

Currently the parameter of skin-tone-enhancement filter is forced
to zero. In fact it could be set different value by the user.
So create a new property named as "skin-tone-enhancement-level"
for accepting the used defined parameter value.
At the same time, skin-tone-enhancement is marked as deprecated.
When skin-tone-enhancement-level is set, skin-tone-enhancement
will be ignored.
