Structure:

GstGL.GLBufferPoolClass

a GstGL.GLBufferPool is an object that allocates buffers with GstGL.GLBaseMemory

A GstGL.GLBufferPool is created with GstGL.GLBufferPool.new()

GstGL.GLBufferPool implements the VideoMeta buffer pool option GstVideo.BUFFER_POOL_OPTION_VIDEO_META, the VideoAligment buffer pool option GstVideo.BUFFER_POOL_OPTION_VIDEO_ALIGNMENT as well as the OpenGL specific GstGL.BUFFER_POOL_OPTION_GL_SYNC_META buffer pool option.

classmethod new(context)

Parameters:

context (GstGL.GLContext) – the GstGL.GLContext to use

Returns:

a Gst.BufferPool that allocates buffers with GstGL.GLMemory

Return type:

Gst.BufferPool

get_gl_allocation_params()

Returns:

a copy of the GstGL.GLAllocationParams being used by the self

Return type:

GstGL.GLAllocationParams or None

The returned GstGL.GLAllocationParams will by None before the first successful call to Gst.BufferPool.set_config(). Subsequent successful calls to Gst.BufferPool.set_config() will cause this function to return a new GstGL.GLAllocationParams which may or may not contain the same information.

New in version 1.20.
