So the reason for the imperfect streams are that matroska has a timecode scale
which in matroskamux is set to 1 millisecond. This means all timestamps and
durations are rounded to nearest millisecond. When matroskademux outputs
timestamp/duration the timestamp does not match up to the previous timestamp +
previous duration therefore and hence the non-perfect decoded stream.

There is a drift between audio and video however, I noticed about 10 seconds
after 9 hours. But this simple test case is not causing the problem. Though we
should fix the imperfect decoded stream.
