// ARC++ to a VDA instance. We plan to deprecate to VDA implementation at
// chromium by new VD implementation. So we need the adapter between
// these two interface.
//
// Important note: This adaptor is only used temporary as an intermediate step
// while the GpuArcVideoDecodeAccelerator is being ported to the new VD
// interface. This Adaptor will be deprecated soon and should not be used
// anywhere else.
