Comment:

 ͏    What's the purpose of "DiscardPadding" after all..?
 ͏    Is the input file precisely broken/invalid?

 https://www.matroska.org/technical/elements.html#DiscardPadding
 ͏    "The duration of DiscardPadding is not calculated in the duration of
 the TrackEntry and !**SHOULD!** be discarded during playback."
