do a search on gstreamer tools - i'm pretty sure it should be able to do it
I'm thinking allong th elines of a script that
# Create the player_name sink
player_name = gst.element_make_factory(“playbin”, “Multimedia Player”)
# Create the fake video sink
fake_video_sink = gst.element_make_factory(“fakesink”, “Fake sink for Videos”)
#Add the fake video sink to the player
player_name.set_property(“videosink”, fake_video_sink)
#Set the file
player_name.set_property(“uri”, “file:///home/peter/mymusic.mp3”)
#Set the State
player_name.set_state(gst.PLAYING)
#Play the file
.....
#After x seconds run gst.STATE_PAUSED or gst.STATE_NULL — Used to stop file
.......
Pretty sure you can use self.time_format = gst.Format(gst.FORMAT_TIME) to figure out where to start / stop too...

Thank you,
this is python code, right?
I need this for a gtk program written in c.
I already found some gstreamer code snippets, but
dont know how much code is needed to initialize and
use gstreamer. I hoped there were a simple API
preferable something in the hildon framework.

Thank you again noobmonkey,
this hint was actually more helpful than I thought.
Here is a short code snippets how to play a sound
with gstreamer in C.

Here is a short code snippets how to play a sound
with gstreamer in C.
Code:
#include <stdlib.h>
#include <gst/gst.h>
// build with gcc -o sound_player sound_player.c $(pkg-config --cflags --libs gstreamer-base-0.10)
int
main (int argc, char *argv[])
{
gst_init (&argc,&argv);
GstElement *player;
GMainLoop* loop;
loop = g_main_loop_new (NULL, FALSE);
if (argc != 2) {
g_print ("usage: %s <audio filename-uri (file:///fullpath/name.mp3)>\n", argv[0]);
exit (-1);
}
player = gst_element_factory_make ("playbin2", "Multimedia Player");
g_object_set (G_OBJECT (player), "uri", argv[1], NULL);
g_assert (player != NULL);
gdouble v = 0.5;
g_object_set(player, "volume", v);
int ret = gst_element_set_state (player, GST_STATE_PLAYING);
g_main_loop_run(loop);
exit (0);
}

Hello,
Does anyone know a commandline exe to play a wav that pulse or silences the current media player?
I had a look at osso-af-utils.. but it doesn't make sense to me what these exe's do.
Looks like espeaktime uses PulseAudio properties via the PULSE_PROP env var.
espeaktime-now.sh:
export PULSE_PROP="module-stream-restore.id=x-maemo-applet-profiles event.id=ringtone-preview"
espeak -w $fname "${@}"
play-sound $fname
rm -f $fname
This doesn't stop/silence the current audio and plays over it

is there a simple API to play a short part of a sound file.
I need this to play a sound preview, the user sees a list
of sound files and everytime he selects another file, I want
to play some seconds from this file.
(Just like the ringtone selector in the profiles settings dialog)
