3.0 SD Card or USB Flash Drive Folder Structure
3.1. MP7XX Folders
The basic folder structure of the SD card or USB flash drive as used on the MP7XX players is as follows:
Html/
Video/
Music/
Picture/
Playlist/
Media files and playlists can be placed in the associated folder. The SD card or USB flash drive is then inserted into the player
and play back is then accomplished by using the IR remote. QS Pro Designer 7X can also be used to “publish” this structure
including the desired content files and playlists to the SD card or USB flash drive.
In addition to HTML code and pages, the HTML folder may contain a configuration file called “xappcfg.txt”. These are used to
set up various parameters for the different Xapps we have available. There are custom ones that we can provide to control the
player via RS-232 or set special volume limits and step sizes.
An example config file for the volume control Xapp is shown below:
video1=M_Series_August.mp4
video2=S4221_fandem.mp4
video3=videofile3
video4=videofile4
video5=videofile5
video6=
video7={vol_down}
video8={vol_up}
loopVideo=August_attractloop.mp4
volume_default=60
volume_max=80
volume_min=10
volume_step=5
ledopt=1
The last parameter “ledopt=x” is used to configure the action of the 8 GPIO pushbutton LEDs. The default is for the LEDs to be
off and only light up when the button is pressed. By setting the “ledopt” to a different number, the behavior may be changed.
Delete the “ledopt” line from the file to return to default behavior.
0 = all leds off always
1 = all leds on always
2 = normally on, active button led on while video plays, others off, when video ends all on
3 = normally off, active button led on while video plays, others off, when video ends all off
4 = normally on, active button led off while video plays, others on, when video ends all on
3.2. MP7XXConfig Folder
An additional folder can be added to the structure that contains control and configuration items. The folder is named
MP7XXConfig/. The MP7XXConfig folder is entirely optional. The structure on the SD card or USB flash drive will then be as
shown below:
Html/
Video/
Music/
Picture/
Playlist/
MP7XXConfig/
3.3. Configuration File (mp7xx.conf file)
The configuration file can be optionally placed inside the MP7XXConfig folder. This is simple text file consisting of a number
of optional commands and configuration settings. The file is named mp7xx.conf. The
X-App Manager is responsible for reading this file and performing the commands and setting the requested configuration items.
This is where you would define the desired default startup item (see 4.2.2).
If the mp7xx.conf file does not exist, the X-App Manager remains passive and the MP7XX player will start play per the default
startup item and operate in the normal manner based on its SNMP command set.
