PRIORITY 1
MML Player behavior depends on media file location
i
?If the M3U folder is empty or no valid M3U files are found then MML player will check for the last used “folder based”
scenario (scenario 2 or scenario 3). If that information is not found or corrupted, then MML player will try to switch to
scenario 2. If according to scenario 2 there are no folders with music files in multimedialinq/music folder then MML will
switch to scenario 3.
?If according to scenario 3 there are no folders with music files in the ROOT folder then MML player will mark this disc
unavailable and will switch to the next available disc if it exists.

Before You Start 11
MML Player will create playlists based on M3U files with “.m3u”
extension located in folder “[ROOT]/multimedialinq/m3u/”. MML Player
accepts playlist's file name as playlist's name (up to 41 characters*).
MML player supports up to 999 playlists (“.m3u files”) and up to 999
media files per playlist file. "m3u" files use the UTF8 encoding.
NEW: MML Player will create list of ARTISTS based on M3U files with
“.m3u” extension located in folder “[ROOT]/multimedialinq/m3u.Artist/”.
NEW: MML Player will create list of ALBUMS based on M3U files with
“.m3u” extension located in folder “[ROOT]/multimedialinq/m3u.Album/”.
An M3U file is a plain text file that contains the locations of one or more
media files that the MML Player should include in a playlist. Each
location is placed on a new line. The locations should be absolute “UNIX
style” path names (e.g., “/multimedialinq/music/PL1/song1.mp3”) or
“Windows style” path names (e.g.,
“\multimedialinq\music\PL1\song1.mp3”). M3U file also can contain
comments prefaced by the "#" character.
Media file can be located anywhere on the same disc where the M3U file
is located, but recommended to organize your media files in such a way
that the pathnames are as short as possible.
M3U file example
#***************************
/multimedialinq/music/Folder1/Song1.mp3

WARNING
!
*MML player accepts playlist's file name as playlist's name. Playlist's file name can contain up to 41 characters plus
file extension, but will only display 26 characters due to radio limitation. (Some Radios can only support 16
characters).
Make sure to create unique playlist file names to be able to recognize your playlists during browsing.
You must use UTF-8 encoding. Line length for M3U file CAN NOT exceed 255 UTF-8 symbols.
To create M3U files we recommend using third party software such as
“ADVANCED MP3 CATALOG“ (http://www.wizetech.com)
“WINAMP” player (http://www.winamp.com)
and etc.
Make sure to use UTF-8 encoding when creating M3U files. The file extension must be M3U and not M3U8.

the playlist's name. Folder's name has no limitation on characters count, as
long as the full path name with file name does not exceed 255 characters.
MML player will only use the first 26 characters to create the playlist name.
In this case the playlist name with up to 26 characters will be displayed on

Example:
“[ROOT]\multimedialinq\music\PlaylistName1\[MP3/WAV media files]”
“[ROOT]\multimedialinq\music\PlaylistName2\[MP3/WAV media files]”
Media files have to be located directly in [Playlist] subfolders to be played
by MML Player. Files located in a playlist's nested subfolders are not
supported. Playlists will be created in order of their physical location in the
music folder. Media files will be organized in order of their physical location

supported.
Playlists will be created in order of their physical location in the music
folder. Media files will be organized in order of their physical location in the
playlist folder.
If MML Player detects that the Mass Storage Device is iPod, it will
assume that source music folder is folder “/iPod_Control/Music”. Since
the iPod's folders names are not informative, it's recommended to use
mode “M3U playlists files”.

MML Player Internal Data Structure
i
MML Player stores all internal data in the folder “multimedialinq”. If that folder is not present on a playable partition, player
will create the folder. Folder structure:
lFolder “control” (CONTROL)
Player will check this folder for CMD file “mmlqcmdf.cmd” to add, modify or remove
data on internal HDD (not applicable for MML);
lFolder “dpls” (DPLS)
Player will use the folder for storing the “folder-based playlists” CACHE files
(modes 1 or 2). File “dpls_cache.pdb” is playlists CACHE file that contains information
about last used “folder-based” operational mode and list of playlists. Subfolder “cache”
contains CACHE files (extension “m3uV”) for each detected playlist;
lFolder “image”
Player will create/use the folder for storing “Storage image” files if such image was
requested in CMD file;
lFolder “m3u” (M3U)
Player will check the folder for M3U playlists files and will use it to store CACHE files in
Scenario 1. Subfolder “cache” contains playlist's CACHE files (extension “m3uV”);
lFolder “m3u.Artist” (M3U.ARTIST)
Player will check the folder for M3U playlists files for category “Artist” and will use it to
store CACHE files in Scenario 1. Subfolder “cache” contains playlist's CACHE files
(extension “m3uV”);
lFolder “m3u.Album” (M3U.ALBUM)
Player will check the folder for M3U playlists files for category “Album” and will use it to
store CACHE files in Scenario 1. Subfolder “cache” contains playlist's CACHE files
(extension “m3uV”);
lFolder “music” (MUSIC)
Recommended location for AUDIO files. It's recommended to organize audio
information according to the description in Scenario 2 “MML Music Folder””;
lFolder “update”
Player will check the folder for software updates;
MML Player and Data “CACHING” Mechanism
i
MML player has been designed to incorporate a caching mechanism.
Every folder and playlist will be pre-processed by MML player and it will create corresponding cache file/s with a list of
songs in the dlps/cache folder (for scenario 2 and scenario 3) to improve MML browsing and playback performance. For
scenario 1, cache file/s will be created in the M3U/cache folder.
MML player will also create an additional cache file “dpls_cache.pdb” with a list of folders/playlists in the dpls folder,
available for scenario 2 and 3.
Add/Remove Music Files Manually:
Cache files have priority over original music data. If original data has been changed or re-created* in at least one
folder or M3U playlist file depending on the scenario used, then you must remove the corresponding cache files to make
sure MML player re-builds the cache. You can remove either one or all files in the cache folder to force MML player to re-
build the cache. We strongly recommend to delete the cache files associated with the changes only. Removing all files from
the cache folder will force MML player to re-build all cache files on this particular disc, which will slow down MML
performance dramatically.
Add/Remove Music Folders Manually:
The cache file “dpls_cache.pdb” has priority over original music data. If the original data has been changed, for
example one folder has been added, removed, or re-created*, then you must remove “dpls_cache.pdb”.
* File or folder was first removed and then created again with the same name.
MML player constantly verifies the cache files against non-existing or non-supported files and folders during operation
in background mode. If it detects a certain amount of bad links, it will try to re-build on the first attempt and will mark
unavailable for playback on the second attempt.

4 partitions per USB storage device and 6 partitions total.
?The vehicle's Radio recognizes every partition as a separate disc.
?Non-playable partitions will not be recognized by MML player.
?The USB storage device becomes available as a source shortly after connection, as an additional DISC. If USB
