Media Library

Introduction

Omnia has built-in media data library. The media data library contains all your media information, including song file paths, title, album, artist, etc.

It will scan your media store database to find media files which you first launch the app, this process is very fast.

If your music files are not detected, you can click "rescan library" from toolbar, and do a complete manual scan. It will scan all your folders and find out all playable media files.

Omnia will try to scan newly added media files and update the media data library automatically, but when your newly added music file is not detected, please use manual rescan.

Scan Scope

By default, all folders on your device will be scanned during manual scan. But if the folder contains ".nomedia" file, then the scanner will skip this folder and its sub-folders.

You can define a blacklist folders, to exclude folders which you do not want the scanner to scan, such as ringtone folders, voicemail folders, etc. Just click "Exclude" menu item or edit the folder list in settings page.

You can define a whitelist folders, to let the scanner only scan the specified folder that you select, and ignore other folders. This is a suggested way, it will improve the scan speed a lot, and filter down other unintended media files.

You can set a minimum length in settings page, such as 6 seconds, then all media files whose playback length are shorter than 6 seconds will be ignored.

For Android 11 and Above

Since Android 11, Android system limits the storage access permission. Then only the files which Android system believes to be media file, will be accessible by Omnia. Then Omnia do not have permission to access many supported files (such as ape file, Android system do not treat it as media file), and some playlist files, or album artwork files.

The solution is manually add the music folders in Omnia settings to whitelist folder list. When you add the folder, Omnia will request the permission to access that folder, after you grant the permission, Omnia can access all contents under that folder and its sub-folders. This way Omnia can scan and find all supported media files on your device.

If you are using Android 11 and above, and find your media files are not detected, please use the whitelist folder feature to add the folder to scan scope manually. The scan speed is slower due to poor performance of Android document API, please be patient and the scan is only one time work, after that all your music will be ready to play, you do not need to scan them everytime when you use Omnia in the future.

Scan Encoding

Before you start the manual rescan, Omnia will ask which encoding you would like to use to parse the song tags. By default, it will use automatic mode, which will detect the encoding automatically. Sometimes the detected encoding is not correct. If you find any garbled characters in the parsed result, such as song title or album name, please change the encoding and rescan again. The most common encoding, besides the automatic mode, is UTF-8, or the encoding which your language is using.

Multiple Artists

Omnia supports multiple artists for each track. By default, it supports &(ampersand) and ;(semicolon) as the artist delimiters. But you can customize the delimiter in settings page, and select .(comma) and /(slash) as delimiters. For instance, if a song has artist named "Mozart & Bach", the song will appear in both artist "Mozart" and artist "Bach".
