                                 GstGLContext *context);

Set a sync point to possibly wait on at a later time.

gst_gl_sync_meta_wait ()

void
gst_gl_sync_meta_wait (GstGLSyncMeta *sync_meta,
                       GstGLContext *context);

Insert a wait into context 's command stream ensuring all previous OpenGL commands before sync_meta have completed.

gst_gl_sync_meta_wait_cpu ()

void
gst_gl_sync_meta_wait_cpu (GstGLSyncMeta *sync_meta,
                           GstGLContext *context);

Perform a wait so that the sync point has passed from the CPU's perspective What that means, is that all GL operations changing CPU-visible data before the sync point are now visible.
