Play photo and video togheter

[Ciubz]

Hi, I have folders with pictures and videos i shoot with my camera in my Qnap NAS with jellyfin.
Would like to autoplay the files from the first one till the end, in my tv with chromecast jellyfin app.
When I play the first picture, only pics will play, video will skip.

Is there a way to play videos too?

Thanks in advance
