GstGLBuffer is a GstMemory subclass providing support for the mapping of GL buffers.
Data is uploaded or downloaded from the GPU as is necessary.
void
gst_gl_buffer_init_once (void);
Initializes the GL Buffer allocator. It is safe to call this function multiple times. This must be called before any other GstGLBuffer operation.
Since: 1.8
