From ff37d7efeca2a53819104039348dfbe39c4aca98 Mon Sep 17 00:00:00 2001 From: Niklas Haas Date: Wed, 8 Jun 2016 11:39:31 +0200 Subject: vo_opengl: refactor performance data properties Instead of having 9 different properties, requiring 18 different VOCTRLs to read them all, they are now exposed as a single property. This is not only cleaner (since they're all together) but also allows querying all 9 of them with only a single VOCTRL (by using mp.get_property_native). (The extra factor of 2 was due to an extra query being needed to get the type, which is now also unnecessary) This makes it much easier to access performance metrics from within a lua script, and also makes it easier to just show a readable, formatted version via show-text. --- DOCS/man/input.rst | 62 ++++++++++++++++++++++++++---------------- options/m_property.h | 2 ++ player/command.c | 77 +++++++++++++++++++++++----------------------------- 3 files changed, 74 insertions(+), 67 deletions(-) diff --git a/DOCS/man/input.rst b/DOCS/man/input.rst index 89bb41c046..d58f2dc4d5 100644 --- a/DOCS/man/input.rst +++ b/DOCS/man/input.rst @@ -894,30 +894,6 @@ Property list .. note:: This is only an estimate.
