@tommydunn Sure Thanks lot

@tommydunn,
Great work!!
Facing some small challenges, if you could help so it would be much appreciate.

1. Slide change without play full video (in case of autoplay)
2. Auto play video not working on slide change, using HTML5 video tag.
   It would be great if you or anyone can help on same.
   thanks in advance.

is there any way if we can add the external mute/unMute buttons for each video?
