Subject: display: add interface to retrieve the display name.
X-Git-Tag: 0.5.9~19
X-Git-Url: http://review.tizen.org/git/?p=platform%2Fupstream%2Fgstreamer-vaapi.git;a=commitdiff_plain;h=7c2c4c7a971680309c0b479b496a2e210e7149fd

display: add interface to retrieve the display name.

Add gst_vaapi_display_get_display_name() helper function to determine
the name associated with the underlying native display. Note that for
raw DRM backends, the display name is actually the device path.
