Could someone give me a hint to solve this problem? Or is it a known issue/ limitation of the application? Would converting the files to FLAC or other media formats help?
Thank you.
Edit:
I think my situation is similar to a comment left on App Store:
The download/media library has stopped working as of the last iOS update. Used to work flawlessly but now when i download videos from my NAS, they do no appear in my media library once completed. I can tell the downloads completed because the iPhone reports VLCs file system usage increased by the same amount as the downloaded file(s). Streaming from my NAS does work perfectly however. Just stuck with an empty media library now.
