From 1c2cbeabc270874c8f14e16c8f7a09c1f0a382d9 Mon Sep 17 00:00:00 2001 From: wm4 Date: Mon, 15 Dec 2014 04:40:26 +0100 Subject: vo_opengl: remove quadbuffer/anaglyph stereo 3D rendering Obscure feature, and I've never heard of anyone using it. The anaglyph effects can be reproduced with vf_stereo3d. The only thing that can't be reproduced with it is "quadbuffer", which requires special and expensive hardware. --- video/out/gl_common.c | 86 -------------------------------------------- video/out/gl_common.h | 8 ----- video/out/gl_video.c | 42 +++------------------- video/out/gl_video.h | 1 - video/out/vo_opengl.c | 3 -- video/out/vo_opengl_old.c | 91 +++++++++++++++++++++++++++++++++++++++++++++++ 6 files changed, 96 insertions(+), 135 deletions(-) (limited to 'video') diff --git a/video/out/gl_common.c b/video/out/gl_common.c index 6cc2d20a17..d9df1aa7ee 100644 --- a/video/out/gl_common.c +++ b/video/out/gl_common.c @@ -773,92 +773,6 @@ void glDownloadTex(GL *gl, GLenum target, GLenum format, GLenum type, gl->GetTexImage(target, 0, format, type, dataptr);
