// requests of buffer allocation to a VideoDecodeAccelerator instance, and
// provide FrameResource to the VideoDecoder instance.
// The communication with VdVideoDecodeAccelerator, which inherits
// VdaDelegate, is executed on |vda_task_runner_|, and the communication with
// VideoDecoder instance is on |parent_task_runner_|.
