// CastDecoderBuffer provides an interface for passing a single frame of audio
// or video data to the pipeline backend. End-of-stream is indicated by passing
// a frame where end_of_stream() returns true.
// The buffer's lifetime is managed by the caller code - it MUST NOT be
// deleted by the MediaPipelineBackend implementation, and MUST NOT be
// dereferenced after completion of buffer push (i.e.
// kBufferSuccess/kBufferFailure for synchronous completion, OnPushComplete
// for kBufferPending case).
// TODO(halliwell): consider renaming functions here to camel case.
