Comment (by Denis Filippov):
As expected, the result is the same for the master branch.
It seems to me that the problem is as follows: the scte-35 data stream
does not have the data itself, but only the presence identifier. The data
appears only when the mark itself is encoded, i.e. when it is present. In
this case, the speed up, and then creeps down to 0.
