be able to request replays of specific events, or ask you to save something

+Audio support
+'''''''''''''
+
+Since version 1.8.5, Futatabi has limited audio support. It is recorded
+(assuming Nageru is also at version 1.8.5 or newer) and saved for all inputs,
+and played back when showing a replay, but only when the replay speed is at
+100%, or very close to it. (At other speeds, you will get silence.)
+Furthermore, there is no local audio output; the Futatabi operator will not
+hear any audio, unless they use a video player into the Futatabi stream locally
+(with associated delay). All of this may change in the future.

Replay workflows

There are two files:
- * `Trøndisk 2018, finals only (MJPEG, 77 GB) <https://storage.sesse.net/trondisk2018-finals-multicam-mjpeg.mkv>`_:
- The final match, in MJPEG format (about 30 minutes). This can be downloaded
- and then fed directly to Nageru as if it were a real camera stream
+ * `Trøndisk 2018, final only (MJPEG, 126 GB) <https://storage.sesse.net/trondisk2018-final-multicam-mjpeg.mkv>`_:
+ The final match, in MJPEG format (about 73 minutes). This can be downloaded
+ and then fed directly to Futatabi as if it were a real camera stream
(remember the --slow-down-input option).
- * `Trøndisk 2018, entire tournament (H.264, 74 GB) <https://storage.sesse.net/trondisk2018-multicam-h264.mp4>`_: The entire tournament,

+ The entire first part of the tournament,
with no cuts (about 12 hours). However, due to space and bandwidth
constraints, it has been transcoded to H.264 (with some associated
quality loss), and needs to be transcoded to MJPEG before Nageru can use it.

Futatabi expects to get data in MJPEG format only; though MJPEG is old,
it yields fairly good quality per bit for an intraframe format, supports
