Class (GI Struct)

GstGL-1.0 ▶ GstGL ▶ GLBaseMemory

GstGLBaseMemory is a Gst.Memory subclass providing the basis of support for the mapping of GL buffers.

Data is uploaded or downloaded from the GPU as is necessary.

Methods

alloc_data

alloc_data(): boolean
Note: only intended for subclass usage to allocate the system memory buffer on demand. If there is already a non-NULL data pointer in gl_mem->data, then this function imply returns TRUE.

Returns boolean
whether the system memory could be allocated
- Defined in gstgl-1.0/gstgl-1.0.d.ts:4553

init

init(
    allocator: Gst.Allocator,
    parent: Memory,
    context: GstGL.GLContext,
    params: AllocationParams,
    size: number,
    user_data?: any,
    notify?: DestroyNotify,
): void
Initializes mem with the required parameters
Parameters
- allocator: Gst.Allocator
  the Gst.Allocator to initialize with
- parent: Memory
  the parent Gst.Memory to initialize with
- context: GstGL.GLContext
  the GstGL.GLContext to initialize with
- params: AllocationParams
  the GstAllocationParams to initialize with
- size: number
  the number of bytes to be allocated
- Optionaluser_data: any
  user data to call notify with
- Optionalnotify: DestroyNotify
  a GLib.DestroyNotify
Returns void
- Defined in gstgl-1.0/gstgl-1.0.d.ts:4564

memcpy

memcpy(dest: GLBaseMemory, offset: number, size: number): boolean
Parameters
- dest: GLBaseMemory
  the destination GstGL.GLBaseMemory
- offset: number
  the offset to start at
- size: number
  the number of bytes to copy
Returns boolean
whether the copy succeeded.
- Defined in gstgl-1.0/gstgl-1.0.d.ts:4579

`Static`alloc

alloc(
allocator: GstGL.GLBaseMemoryAllocator,
params: GLAllocationParams,
): GLBaseMemory
Parameters
- allocator: GstGL.GLBaseMemoryAllocator
  a GstGL.GLBaseMemoryAllocator
- params: GLAllocationParams
  the GstGL.GLAllocationParams to allocate the memory with
Returns GLBaseMemory
- Defined in gstgl-1.0/gstgl-1.0.d.ts:4538

`Static`init_once

init_once(): void
Initializes the GL Base Memory allocator. It is safe to call this function multiple times. This must be called before any other GstGLBaseMemory operation.

Returns void
- Defined in gstgl-1.0/gstgl-1.0.d.ts:4543
