New description:
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 depending on
the situation) 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.
