 Summary of the bug: It is currently not possible to set the
 `suggestedPresentationDelay` in generated mpd files in all cases in the
 ffmpeg DASH muxer. The default value chosen (1 segment length) results in
 unusable playback in many situations if using a player that tries to
 respect ffmpeg's chosen delay.

 If unwilling to provide a knob, defaulting it to a small multiple of the
 segment duration is a saner default that won't break players that try to
 respect it. See https://dashif.org/docs/DASH-IF-IOP-v4.2-clean.htm e.g.
