Media Player

The media viewer application for mobile devices. This is not the spec for the underlying engine (e.g. gstreamer, helix, etc). The media player for UME will have a finger-navigable UI capable of viewing photos, playing music and videos, and using either the gstreamer or helix media engines with a common interface to them. The UI will follow the recommendations in the UI Style Guide

Rationale

There are some existing media applications but none seem to cover all of the features needed and be tailored for a MID, so a new UI is being written. The goal is to simplify the media management on the MID and provide a single place for viewing and listening to media.

Gstreamer and Helix media engines will be supported with dynamic discovery of the content types supported by whichever engine is present at runtime. Helix support is being included primarily for DRM solutions.

The entire scope of media management is large, from the first time a user obtains some content to consuming it on the device. The following section describes the full spectrum with the ones outside the scope of this application shown in red. Additional functionality may be added as time and resources permit.

Comments welcome.

Functional Specification

PC = non-mobile device, such as a Linux or Windows desktop

MID = Mobile Internet Device.

Content = music files (mp3, etc), movies (.mpg, etc), photos (.jpg, etc)

Media viewer = Multimedia application on MID

1. Content Management on the PC

(Currently not planned) There are a few choices for music management on the PC (e.g. Windows Media Player, ITunes, Banshee). For movie and photo management, users often use the filesystem directly. Eventually a new "MID Content Manager" application could be written.

2. Getting content to the device

2.1 Syncing

* Auto-sync with an application that manages content on the PC. This involves writing a new plugin or application that pushes the content from one of the following applications to the MID when the MID is plugged in via USB.

* Only sync down (all content is pushed to MID. Any MID content changes are lost

* Sync in both directions: content is merged on PC and MID. Conflicts are resolved by asking user for preference.

* Auto-sync with a file directory on the PC (just file system). Application registered when MID is plugged in to USB to auto-sync contents.

Manual-sync: Plug MID into USB port. MID file system exposed to PC. User drags/drops files from PC to the MID file system.

Sharing

* Auto-detect other MIDs in area via bluetooth. Connect. Display shared content from each MID on other MID. User can download content to their MID.

Receive email with content. Save content to MID filesystem.

User Download on MID

On MID, download content from internet via the browser
On MID, download/upload content from wired or wireless connection to remote filesystem over network

Content Management on MID

User can:
View content name, artist, album, length, genre, music format, times played, last played date/time

View content as resizable thumbnails
View 3D-flipping album art
Select content
Select multiple files at the same time

Organize content folders, create new folders, name folders, move content between folders

* Assign content metadata: Name, Artist, Album, genre, cover art

* Auto-lookup music metadata online from CDDC: Name, artist, album, cover art

Create, delete, edit playlists
Sort music by: Name, Date, length, Artist, Album, genre, type (mp3, wav, etc)

Slideshow
Create a slideshow of photos
Assign a music file to play when slideshow is started
Assign a music playlist to play when slideshow is started
Set the time delay between photo transitions
Set transition effect between pictures (fade, slide, etc)

Plugin applications will be started with the paths to all the content as command-line parameters. Examples include internet upload, email, or any application to manipulate content.

Theme / Skin

Media viewer will use the system theme for all standard Hildon and GTK controls such as buttons, scrollbars, and dialogs.
User can change the skin of the MID media viewer

Media Engine

Media viewer will be capable of using gstreamer or helix media playback engines
User can select which media engine to use first, or exclusively
Media viewer will dynamically discover what content types each media engine supports and attempt to playback content on the correct engine
