st/va: add preset values for VAAPI encode
Add some hardcoded values hardware needs mainly for rate control purpose. With previously hardcoded values for OMX, the rate control result is not correct. This change fixed the rate control result by setting correct values for Vaapi. Signed-off-by: Boyuan Zhang <[email protected]>
