Playback error on folders list (Photos library with home videos)

[nonobio]

Hi,

I'm new to Jellyfin,  but first I want to say thank you for this software, it seems to be great .

I have an annoying problem:
I have created a Photos library for my home videos and I have a Playback Error: This client isn't compatible with the media and the server isn't sending a compatible media format. when I try to Play All or Shuffle on my folder list (from web or android client, even from local web client where is installed Jellyfin).

The issue is present event if I have only one or two video in this simple folder structure:

G:\mainfolder\subfolder\videofile1.mp4
---------------------------\videofile2.mp4



If I press the 3 dots buttons on subfolder and press Shuffle or start playback on videofiles list (inside subfolder), playback works:


Do you have an idea of the problem?

Steps to reproduce the issue

1. Put videofile1.mp4 and videodile2.mp4 into G:\mainfolder\subfolder\
   
2. Add Media Library
   
3. Content type: Photos
   
4. Display name: homevideos
   
5. Folder G:\mainfolder
   
6. Ok, Ok
   
7. Go to Media: homevideos
   
8. Play All or Shuffle
