libs: move get_surface_formats to utils_core The query of all the supported formats for a VA config were only used by the postprocessor (vaapifilter). But, in order to enable the vaapidecoder to negotiate a suitable raw format with downstream, we need to query these formats against the decoder's config. This patch is the first step: moves the code in filter's ensure_image() to a generic gst_vaapi_get_surface_formats() in vaapiutils_core, so it can be shared later by the decoder. https://bugzilla.gnome.org/show_bug.cgi?id=752958 2016-02-18 18:20:10 +00:00			`/* Gets the available GstVideoFormats of a surface in a VAConfig */`
