Subject: tests: simple-decoder: set window size to the surface dimensions.
X-Git-Tag: 0.5.1~38
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7b4dadc8ae0ee9a8b0ec531264a4348ee646c6b4;p=platform%2Fupstream%2Fgstreamer-vaapi.git

tests: simple-decoder: set window size to the surface dimensions.

Set the window size to the decoded surface dimensions, if the user has
not requested the application to run in full-screen mode. Besides, no
effort is made to preserve aspect ratio or to center the video within
the mapped window.
