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

Since 1.8init

• init(
      allocator: Gst.Allocator,
      parent: Memory,
      context: GstGL.GLContext,
      params: AllocationParams,

      user_data: null,
  ): void

  Initializes mem with the required parameters

  Parameters

  • allocator: Gst.Allocator

    the Gst.Allocator to initialize with

  • parent: Memory

  • context: GstGL.GLContext

    the GstGL.GLContext to initialize with

  • params: AllocationParams

    the GstAllocationParams to initialize with

  • size: number | bigint

    the number of bytes to be allocated

  • user_data: null

    user data to call notify with

  Returns void

Since 1.8memcpy

• memcpy(
      dest: GLBaseMemory,
      offset: number | bigint,
      size: number | bigint,

• alloc(
      allocator: GstGL.GLBaseMemoryAllocator,
      params: GLAllocationParams,
  ): GLBaseMemory

  Parameters

  • allocator: GstGL.GLBaseMemoryAllocator

StaticSince 1.8init_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
