From 61a8f3444226fd561f5c16f2cdc9a3d069568620 Mon Sep 17 00:00:00 2001 From: Julien Isorce Date: Sun, 15 Mar 2009 14:48:19 +0100 Subject: [PATCH] [321/906] add OpenGL ES 2.x support. In OpenGL 2.x for Embedded System, a lot of basic scene/draw functions have been removed. It means that everything is made using vertex and fragment shaders. I have also added a gstglwindow backend for winCE that uses EGL (Native Platform Graphics Intercace) (which is a full part of OpenGL ES specification). It remove the use of wgl/glx functions. --- gst-libs/gst/gl/gstgldisplay.c | 732 ++++++++++++++++++++++++++++++++++-- gst-libs/gst/gl/gstgldisplay.h | 22 ++ gst-libs/gst/gl/gstgles2.h | 117 ++++++ gst-libs/gst/gl/gstglshader.c | 16 + gst-libs/gst/gl/gstglshader.h | 9 + gst-libs/gst/gl/gstglwindow.h | 10 + gst-libs/gst/gl/gstglwindow_winCE.c | 610 ++++++++++++++++++++++++++++++ 7 files changed, 1492 insertions(+), 24 deletions(-) create mode 100644 gst-libs/gst/gl/gstgles2.h create mode 100644 gst-libs/gst/gl/gstglwindow_winCE.c diff --git a/gst-libs/gst/gl/gstgldisplay.c b/gst-libs/gst/gl/gstgldisplay.c index e250117..42f3abf 100644 --- a/gst-libs/gst/gl/gstgldisplay.c +++ b/gst-libs/gst/gl/gstgldisplay.c @@ -51,6 +51,9 @@ void gst_gl_display_thread_destroy_context (GstGLDisplay * display);
