Description

a GstGLBufferPool is an object that allocates buffers with GstGLBaseMemory

A GstGLBufferPool is created with gst_gl_buffer_pool_new()

GstGLBufferPool implements the VideoMeta buffer pool option GST_BUFFER_POOL_OPTION_VIDEO_META, the VideoAligment buffer pool option GST_BUFFER_POOL_OPTION_VIDEO_ALIGNMENT as well as the OpenGL specific GST_BUFFER_POOL_OPTION_GL_SYNC_META buffer pool option.

gst_gl_buffer_pool_new (GstGLContext *context);

Parameters

context

the GstGLContext to use

Returns

a GstBufferPool that allocates buffers with GstGLMemory
