The NxPlayer
|
||||
------------
|
||||
|
||||
The NxPlayer is a audio library and command line application for playing
|
||||
audio file. The NxPlayer can be found at apps/system/nxplayer. If you
|
||||
would like to add the NxPlayer, here are some recommended configuration
|
||||
settings.
|
||||
|
||||
First of all, the NxPlayer depends on the NuttX audio subsystem. See the
|
||||
"WM8904 Configuration" above for an example of how the audio subsystem is
|
||||
configured to use the WM8904 CODED with PCM decoding.
|
||||
|
||||
Then the NxPlayer can be enabled as follows:
|
||||
|
||||
System Libraries and NSH Add-Ons -> NxPlayer media player / command line ->
|
||||
CONFIG_SYSTEM_NXPLAYER=y : Build the NxPlayer library
|
||||
CONFIG_NXPLAYER_PLAYTHREAD_STACKSIZE=1500 : Size of the audio player stack
|
||||
CONFIG_NXPLAYER_COMMAND_LINE=y : Build command line application
|
||||
CONFIG_NXPLAYER_INCLUDE_HELP=y : Includes a help command
|
||||
CONFIG_NXPLAYER_INCLUDE_DEVICE_SEARCH=n : (Since there is only one audio device)
|
||||
CONFIG_NXPLAYER_INCLUDE_PREFERRED_DEVICE=y : Only one audio device is supported
|
||||
CONFIG_NXPLAYER_FMT_FROM_EXT=y : (Since only PCM is supported)
|
||||
CONFIG_NXPLAYER_FMT_FROM_HEADER=n : (Since only PCM is supported)
|
||||
CONFIG_NXPLAYER_INCLUDE_MEDIADIR=y : Specify a media directory
|
||||
CONFIG_NXPLAYER_DEFAULT_MEDIADIR="/mnt/sdcard" : See below
|
||||
CONFIG_NXPLAYER_RECURSIVE_MEDIA_SEARCH=y : Search all sub-directories
|
||||
CONFIG_NXPLAYER_INCLUDE_SYSTEM_RESET=y : Add support for reset command
|
||||
|
||||
You must include the full path to the location where NxPlayer can find the
|
||||
media files. That path is given by CONFIG_NXPLAYER_DEFAULT_MEDIADIR.
|
||||
Here I use the example "/mnt/scard". That is a location where you could,
|
||||
for example, mount an MMC/SD card driver.

A command line media player using the on-board WM8904 audio CODEC.
|
||||
This configuration is based on the nsh configuration above with the
|
||||
following extensions:
|
||||
|
||||
a. It runs at 528MHz
|
||||
b. It includes SDRAM support
|
||||
c. Support for the WM8904 audio CODEC is enabled along with
|
||||
support for TWI0, SSC0, and DMAC0 needed by the SM8904.
|
||||
d. Support for the full size SD card slot (HSMCI0) is enable
|
||||
e. The NxPlayer command line media player is built in.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. See the NOTEs for the nsh configuration. Since this configuration
|
||||
derives from that configuration, all notes apply.
|
||||
|
||||
2. Using NxPlayer
|
||||
|
||||
This configuration depends on media files in the default mountpoint
|
||||
at /mnt/sdard. You will need to mount the media before running
|
||||
NxPlayer, Here are the general steps to play a file:
|
||||
|
||||
a. You will need an (full size) SD card containing the .WAV files
|
||||
that you want to play (.WAV is only format supported as of this
|
||||
writing). That SD card should be inserted in the HSMCI0 media
|
||||
slot A (best done before powering up).
|
||||
|
||||
b. If the NuttX auto-mounter is enabled and properly configured,
|
||||
then the FAT file system appear at /mnt/sdcard. If the auto-
|
||||
mounter is not enabled, then here are the steps to manually
|
||||
mount the FAT file system:
|
||||
|
||||
Then from NSH prompt, you need to mount the media volume like:
|
||||
|
||||
nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard
|
||||
|
||||
NOTE: There is an auto-mounter that could be used to eliminate
|
||||
this step. The automounter is not enabled or integrated into
|
||||
in this configuration, however. See the sectino entitle
|
||||
"Auto-Mounter " above
|
||||
|
||||
c. Then you can run the media player like:
|
||||
|
||||
nsh> nxplayer
|
||||
nxplayer> device pcm0
|
||||
nxplayer> play <filename>
|
||||
|
||||

||||

||||
