Hello everyone!
It seems that with the new krPano version (v1.16.x) the (almost) seamless video looping got a little jumpy...
For a better understanding, I made a quick example here (be advised: may cause epileptic seizures 
) :
The integrated video has a duration of about 5 seconds and has the "loop" attribute set to "true".
The first video is played via the old videoplayer from version 1.0.8.15 (man...do i love the new versioning scheme 
). So far the restart of the short video clip goes pretty smooth.
The next two are showing the playback via krPano 1.16.x. Here, before repeating the video, a short flicker occurs. If the movie still had sound, one could also hear the audio stream restarting, resulting in an overall bad experience when looping videos.
So Klaus...any chance to bring the old behavior back again?
As always...best Regards!
