Loading XSPF from network share fails with "The location vlc://nop cannot be played." message
I have some IP Cameras that are configured to push recordings to an open network share. The camera manufacturer's firmware places them in a convoluted path structure so I created a script that runs periodically to scan the folders the cameras place them in and generate an XSPF playlist with a node tree following this documentation. The playlist works flawlessly on VLC desktop for both MacOS and Windows, but fails to load with a "The location vlc://nop cannot be played." message on Android.
Expected behavior
Load playlist with tree structure as it does on Desktop - Screenshot of loaded playlist with tree on MacOS VLC:
Actual behavior
"The location vlc://nop cannot be played." When attempting to load the following playlist from the open network share:
