Random video with fixed timeline

I have 150 videos library with different running length

i want to to play random video files for every alternate 5 mins

the video should end excatly in 5 mins and start the same where it ended in next 5 mins

how i can do that

can some body somebody configure it to me on my xibo

That’s not something that Xibo can do for you I’m afraid. It doesn’t have a concept of showing random items from a region timeline, nor does it support pausing a media item part way through and then resuming it afterwards.
