From 37319ab64452a605c4178711227383f0df31473e Mon Sep 17 00:00:00 2001 From: wm4 Date: Fri, 13 Dec 2013 22:25:38 +0100 Subject: video: change --video-zoom behavior Use the scaled video size (i.e. as shown on the window) as reference for zoom. This is the easiest way to fix different width/height scale factors as they happen when zooming video with a pixel aspect ratio other than 1:1. Also fix the unscaled mode, so that it 1. doesn't scale even with --video-zoom, and 2. doesn't scale by small amounts when the video is cropped by making the window smaller than the video. --- DOCS/man/en/options.rst | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) (limited to 'DOCS') diff --git a/DOCS/man/en/options.rst b/DOCS/man/en/options.rst index 9739a54d5b..584567bc50 100644 --- a/DOCS/man/en/options.rst +++ b/DOCS/man/en/options.rst @@ -2667,6 +2667,10 @@ OPTIONS ``--video-zoom`` option is set to a value other than ``1``, scaling is enabled, but the video isn't automatically scaled to the window size.) + The video and monitor aspects aspect will be ignored.
