From e1fd80097c6c224c9de06182d0a9aa0d21a57a67 Mon Sep 17 00:00:00 2001 From: Niklas Haas Date: Thu, 20 Aug 2015 21:45:58 +0200 Subject: vo_opengl: add tscale-clamp option This significantly reduces the amount of noticeable flashing when using tscale kernels with negative lobes, by cutting them off completely. I'm not sure if this has any negative effects. It needs a bit of subjective testing over a period of time, so I just made it an option. Fixes #2155. --- DOCS/man/vo.rst | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'DOCS') diff --git a/DOCS/man/vo.rst b/DOCS/man/vo.rst index da9bebe115..1865d848bb 100644 --- a/DOCS/man/vo.rst +++ b/DOCS/man/vo.rst @@ -506,6 +506,12 @@ Available video output drivers are: limitations in the number of video textures that can be loaded simultaneously. + ``tscale-clamp`` + Clamp the ``tscale`` filter kernel's value range to [0-1].
