From 654721c27bc0b2ca5fe27a5932b42332c1674547 Mon Sep 17 00:00:00 2001 From: Niklas Haas Date: Wed, 26 Oct 2016 16:32:57 +0200 Subject: filter_kernels: add ability to taper kernels/windows This allows us to define the tukey window (and other tapered windows). Also add a missing option definition for `wblur` while we're at it, to make testing out window-related stuff easier. --- DOCS/man/options.rst | 19 +++++++++++++------ 1 file changed, 13 insertions(+), 6 deletions(-) (limited to 'DOCS') diff --git a/DOCS/man/options.rst b/DOCS/man/options.rst index 45c0bca2f1..3fd3b62d85 100644 --- a/DOCS/man/options.rst +++ b/DOCS/man/options.rst @@ -3874,12 +3874,19 @@ The following video options are currently all specific to ``--vo=opengl`` and never interpolate, thus behaving as if the regular nearest neighbour algorithm was used.
