This is a very simple play application which plays a file in WAV format to a local timeslot. It normally keeps repeating the file until told to stop.
Go to directory $(TiNG)/test.
You must have downloaded firmware modules as listed below.
Run hplaywav with the appropriate options (the program is
gen-LINUX_V6/hplaywav or
gen-WINNT_V6/hplaywav
depending on which operating system you are using).
Command line options are:
-a 1
| use AGC |
-m <module>
| The Prosody module to use. This is the number of the module on the card. |
-s <speed>
| play faster or slower (as a percentage) |
-t <timeslot>
| timeslot to use (see Test program timeslots). |
-v <volume>
| adjust volume of the playback by this (in dB) |
-x <cardspec>
| Use a Prosody processor module on this card, specified as described in Test programs: Specifying Prosody Processor modules |
| <file> | name of file from which data is to be played. |
For example,
gen-WINNT_V6/hplaywav -x x:1.2.3.4/mykey -t 64:0 foo.wav
would play data from
foo.wav to timeslot 64:0.
The firmware modules that are required depend on the format of the data in the WAV file, the options you specify, and the commands you use while it is running. Here are the details:
| Module | When needed |
|---|---|
| datafeed | always on Prosody X |
| gainbg | If you use '-a 1' for AGC
or '-v' to adjust the volume
|
| fast | If you use '-s' to play the file
faster than normal
|
| slow | If you use '-s' to play the file
slower than normal
|
| outchan | always |
| sixkout | when the file format is ACUBLKPCM@6000, ALawPCM@6000, OKIADPCM@6000, or ULawPCM@6000 |
| playA | when the file format is ALawPCM@6000 or ALawPCM@8000 |
| playima | when the file format is IMAADPCM |
| playmu | when the file format is ULawPCM@6000 or ULawPCM@8000 |
| playoki | when the file format is OKIADPCM@6000 or OKIADPCM@8000 |
When this program starts, it starts playing the file and also reads commands. The commands available are:
| Character | Meaning |
|---|---|
| (i.e. blank line - no command) Print status | |
? | Print summary of possible commands |
a N | Change AGC to N |
q | Quit - exit without waiting for channel to finish. |
s N | Set speed to N |
v N | Set volume to N |
| EOF | Wait for channel to finish and quit |
The source code for this program is provided (hplaywav.c).
This is one of the Prosody test programs .
