+\item Can all the subtitle period notation code go?
+\end{itemize}

+\subsection{Steps}
+
+\begin{itemize}
+\item Add signals to \texttt{Player}.
+ \begin{itemize}
+ \item \texttt{signal<void (shared\_ptr<PlayerVideo>), DCPTime> Video;}
+ \item \texttt{signal<void (shared\_ptr<AudioBuffers>, DCPTime)> Audio;}
+ \item \texttt{signal<void (PlayerSubtitles, DCPTimePeriod)> Subtitle;}
+ \end{itemize}
+ \item Remove \texttt{get()}-based loops and replace with \texttt{pass()} and signal connections.
+ \item Remove \texttt{get()} and \texttt{seek()} from decoder parts; add emission signals.
+ \item Put \texttt{AudioMerger} back.
+ \item Remove \texttt{during} stuff from \texttt{SubtitleDecoder} and decoder classes that use it.
+ \item Rename \texttt{give} methods to \texttt{emit}.
+ \item Remove \texttt{get} methods from \texttt{Player}; replace with \texttt{pass()} and \texttt{seek()}.
