why not use VCP?

A bunch of places already refer to the inner type (implicitly by inheritance) so
this felt simpler.  Follow-up cleanup, maybe.

 
   // Enumeration of potential errors generated by the API.
   // Note: Keep these in sync with PP_VideoDecodeError_Dev.

     // An operation was attempted during an incompatible decoder state.
     ILLEGAL_STATE = 1,
