GstGLBufferPool

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.

Constructors

gst_gl_buffer_pool_new

GstBufferPool *
gst_gl_buffer_pool_new (GstGLContext * context)

Parameters:

context

the GstGLContext to use

Returns

a GstBufferPool that allocates buffers with GstGLMemory


GstGL.GLBufferPool.prototype.new

function GstGL.GLBufferPool.prototype.new(context: GstGL.GLContext): {
    // javascript wrapper for 'gst_gl_buffer_pool_new'
}

Parameters:

context (GstGL.GLContext)

the GstGL.GLContext to use

Returns (Gst.BufferPool)

a Gst.BufferPool that allocates buffers with GstGL.GLMemory


GstGL.GLBufferPool.new

def GstGL.GLBufferPool.new (context):
    #python wrapper for 'gst_gl_buffer_pool_new'

Parameters:

context (GstGL.GLContext)

the GstGL.GLContext to use

Returns (Gst.BufferPool)

a Gst.BufferPool that allocates buffers with GstGL.GLMemory


Methods

gst_gl_buffer_pool_get_gl_allocation_params

GstGLAllocationParams *
gst_gl_buffer_pool_get_gl_allocation_params (GstGLBufferPool * pool)

The returned GstGLAllocationParams will by NULL before the first successful call to gst_buffer_pool_set_config. Subsequent successful calls to gst_buffer_pool_set_config will cause this function to return a new GstGLAllocationParams which may or may not contain the same information.

Parameters:

pool

the GstGLBufferPool

Returns ( [transfer: full])

a copy of the GstGLAllocationParams being used by the pool

Since : 1.20


GstGL.GLBufferPool.prototype.get_gl_allocation_params

function GstGL.GLBufferPool.prototype.get_gl_allocation_params(): {
    // javascript wrapper for 'gst_gl_buffer_pool_get_gl_allocation_params'
}

The returned GstGL.GLAllocationParams will by null before the first successful call to Gst.BufferPool.prototype.set_config. Subsequent successful calls to Gst.BufferPool.prototype.set_config will cause this function to return a new GstGL.GLAllocationParams which may or may not contain the same information.

Parameters:

Returns (GstGL.GLAllocationParams)

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

Since : 1.20


GstGL.GLBufferPool.get_gl_allocation_params

def GstGL.GLBufferPool.get_gl_allocation_params (self):
    #python wrapper for 'gst_gl_buffer_pool_get_gl_allocation_params'

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.

Parameters:

Returns (GstGL.GLAllocationParams)

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

Since : 1.20
