From 6789f9b09411f83034883357303b4acfda9569ed Mon Sep 17 00:00:00 2001 From: wm4 Date: Wed, 5 Oct 2016 12:18:44 +0200 Subject: vo_opengl: disable glFlush() by default, and add an option to enable it It seems this can cause issues with certain platforms, so better to disable it by default. The original reason for this isn't overly justified, and display-sync mode should get rid of the need for it anyway. The new option is meant for testing, and will probably be removed if nobody comes up and reports that enabling the option actually improves anything. --- video/out/opengl/video.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'video/out/opengl/video.c') diff --git a/video/out/opengl/video.c b/video/out/opengl/video.c index fa170f61c9..9be12dee21 100644 --- a/video/out/opengl/video.c +++ b/video/out/opengl/video.c @@ -412,6 +412,7 @@ const struct m_sub_options gl_video_conf = { OPT_INTRANGE("opengl-tex-pad-x", tex_pad_x, 0, 0, 4096), OPT_INTRANGE("opengl-tex-pad-y", tex_pad_y, 0, 0, 4096), OPT_SUBSTRUCT("", icc_opts, mp_icc_conf, 0), + OPT_FLAG("opengl-early-flush", early_flush, 0), {0} }, @@ -2848,7 +2849,8 @@ done: // The playloop calls this last before waiting some time until it decides // to call flip_page().
