-\emph{Encoder} calls \texttt{Player::pass()} repeatedly.
-
-\subsection*{Player::pass()}
-
-Look through all `pieces' (content, decoder, video/audio position) and
-find earliest last emission.  Call \texttt{pass()} on earliest
-decoder.
-
-\subsection*{FFmpegDecoder::pass()}
-
-Decoder may or may not generate a frame.  Adjust for gaps in PTS.
-(FFmpegDecoder does FFmpeg filtering here).
-
-\subsection*{VideoDecoder::video(image, same, frame)}
-
-The \emph{frame} parameter is the frame within the source.  This
-handles 3D and emits \texttt{Video}, which is caught by
-\texttt{Player::process\_video}.
-
-\subsection*{Player::process\_video(piece, image, eyes, same, frame)}
-
-\begin{itemize}
-\item Trim
-\item Crop
-\item Scale
-\item Superposition of burnt-in subtitles.
-\end{itemize}
-
-Emits \texttt{Video} which is caught by \texttt{Encoder::process\_video}.
