// This file contains a variety of conservative compile-time assertions that
// help us detect changes that may break the backward compatibility requirement
// of the StableVideoDecoder API. Specifically, we have static_asserts() that
// ensure the type of the gfx struct member is *exactly* the same as the
// corresponding mojo struct member. If this changes, we must be careful to
// validate ranges and avoid implicit conversions.
//
// If you need to make any changes to this file, please consult with
