From 9f3dd1518347ef1e37300fe2c4b9bf4668ec5a06 Mon Sep 17 00:00:00 2001 From: Rob Bradford Date: Tue, 12 Feb 2013 11:53:47 +0000 Subject: [PATCH] shell: Bypass fullscreen scaling if surface width and height match output If our surface has width and height set to the same dimensions as the output then we can bypassing the scale factor calculation and addition of the transformation. The use case that led to this optimisation is the playback of video using gstreamer-vaapi with the "scale" method. The video is the same dimensions as the output (1080p.) --- src/shell.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/src/shell.c b/src/shell.c index 72d2a73..6b0f574 100644 --- a/src/shell.c +++ b/src/shell.c @@ -1672,6 +1672,13 @@ shell_configure_fullscreen(struct shell_surface *shsurf) center_on_output(surface, shsurf->fullscreen_output); break; case WL_SHELL_SURFACE_FULLSCREEN_METHOD_SCALE: + /* 1:1 mapping between surface and output dimensions */ + if (output->width == surface->geometry.width && + output->height == surface->geometry.height) { + weston_surface_set_position(surface, output->x, output->y); + break; + } + matrix = &shsurf->fullscreen.transform.matrix; weston_matrix_init(matrix); -- 2.7.4
