1Of course you will experience lag running unspecified video streaming on an an unspecified computer, running unspecified other tasks, with unspecified resources available. Do you have any other questions?– waltinatorJun 25, 2015 at 3:17

In PulseAudio Volume Control, in the tab Output Devices,
expand the section Advanced for the output device in question.
You can set a latency offset as millisecond value in the advanced section of each device.
That value can be positive or negative; There are other options in the advanced section that may be related to the synchronisation with video.
There are changes in the synchronisation that need support from the video player side, because the player can show the video before even delivering the audio data to the audio system. So it is not clear whether the problem can be solved with the player you use, or a different video player.
Note that reducing lag of sound may be possible by reducing internal default latency delays.
