From 36011c7f6dbda356d64af3866305a036044333fa Mon Sep 17 00:00:00 2001 From: Niklas Haas Date: Mon, 23 Feb 2015 19:06:18 +0100 Subject: filter_kernels: add blur parameter to jinc This affects all filters that use it, eg. ewa_lanczos. Setting it to something like 0.95 can be done to make the filter a bit less blurry. --- 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 7da0d2efff..4fdc0e26c7 100644 --- a/DOCS/man/vo.rst +++ b/DOCS/man/vo.rst @@ -340,6 +340,12 @@ Available video output drivers are: Scale parameter (``t``).
