From 39cab760b3a335942219bf0534ebcc35e2a924a2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Kacper=20Michaj=C5=82ow?= Date: Sun, 12 Nov 2023 22:31:29 +0100 Subject: [PATCH] vo: delay vsync samples by at least 10 refreshes This filters out vastly inaccurate values from presentation feedback that can happen shortly after restarting playback or seeking. Makes estimated vsync converge almost instantly instead of waiting until those outliers are dropped from the past samples. --- video/out/vo.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/video/out/vo.c b/video/out/vo.c index 3e75cc57b8cf8..8027763eab977 100644 --- a/video/out/vo.c +++ b/video/out/vo.c @@ -423,6 +423,7 @@ static double vsync_stddef(struct vo *vo, double ref_vsync) } #define MAX_VSYNC_SAMPLES 1000 +#define DELAY_VSYNC_SAMPLES 10 // Check if we should switch to measured average display FPS if it seems // "better" then the system-reported one.
