I am not sure of what you are doing:
- do you have a normal file and are trying to play it faster/slower ?
- or are you creating a special file that play at a speed that is not the
default one ?

VLC does not read them.

And vlc won't like stream without dts/pts.

VLC master might have a better behaviour with slow/fast (the transition should
be ~ instantaneous when vlc is asked to play faster/slower).
