From d0924ae5a87121d91d59259661dd262eb03becd6 Mon Sep 17 00:00:00 2001 From: wm4 Date: Mon, 4 Mar 2013 00:38:04 +0100 Subject: gl_common: add some sort of locking API Some OpenGL implementations on some platforms require that a context is current only on one thread. For this reason, mpgl_lock() and mpgl_unlock() take care of this as well for convenience. Each backend that needs thread safety should provide it's own locking strategy inside of `set_current`. --- video/out/gl_common.h | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'video/out/gl_common.h') diff --git a/video/out/gl_common.h b/video/out/gl_common.h index 1f28d87855..18d1cf8879 100644 --- a/video/out/gl_common.h +++ b/video/out/gl_common.h @@ -26,6 +26,7 @@ #include #include +#include #include "config.h" #include "core/mp_msg.h" @@ -111,6 +112,7 @@ typedef struct MPGLContext { int (*vo_init)(struct vo *vo); void (*vo_uninit)(struct vo *vo); void (*releaseGlContext)(struct MPGLContext *); + void (*set_current)(struct MPGLContext *, bool current); // Resize the window, or create a new window if there isn't one yet. // On the first call, it creates a GL context according to what's specified @@ -136,6 +138,12 @@ typedef struct MPGLContext { MPGLContext *mpgl_init(struct vo *vo, const char *backend_name); void mpgl_uninit(MPGLContext *ctx); +void mpgl_lock(MPGLContext *ctx); +void mpgl_unlock(MPGLContext *ctx); +void mpgl_set_context(MPGLContext *ctx); +void mpgl_unset_context(MPGLContext *ctx); +bool mpgl_is_thread_safe(MPGLContext *ctx); + // Create a VO window and create a GL context on it. // (Calls config_window_gl3 or config_window+setGlWindow.) // gl_caps: bitfield of MPGL_CAP_* (required GL version and feature set) -- cgit v1.2.3
