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.

nxplayer
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>
