I want to play all audio medias that are supported by gst. Need "seek", "pause", "eos", 
"getposition", "gettotal", "getmode (PLAY, PAUSE, ...)" and "setmode" Features. So let's say 
standard audio player features....

All other formats (WAV, WMA, MP3, FLAC, ...) are working pretty well. So I can't be that 

used packages:
- gstreamer-0.8.10
- gst-plugins-0.8.10
- gst-ffmpeg-0.8.5

totem: will have a look at it.

I used main parts from "examples/manual/threads.c".
decodebin.c example does not use a thread and threads.c use a gst_main(), that I do not 
have. But please see my code snippet below.

What example should I use ? And what have to be changed ?


gst_init(NULL, NULL);

// loading plugins manually (no registry.xml on target...)
// but it doesn't matter. have the same problem on my normal 
// workstation linux

main = gst_thread_new("main");
g_signal_connect(G_OBJECT(main), "state-change", G_CALLBACK(main_state_change), NULL);

src = gst_element_factory_make("filesrc", "src");
g_object_set(G_OBJECT(src), "location", filename, NULL);

dec = gst_element_factory_make("decodebin", "dec");
g_signal_connect(G_OBJECT(dec), "new-decoded-pad", G_CALLBACK(main_newpad), NULL);

sink = gst_element_factory_make("alsasink", "sink");
g_signal_connect(G_OBJECT(sink), "eos", G_CALLBACK(main_eos), NULL);

gst_bin_add_many(GST_BIN(main), src, dec, NULL);
gst_element_link_many(src, dec, NULL);

gst_element_set_state(sink, GST_STATE_PAUSED);
gst_element_set_state(main, GST_STATE_PLAYING);


static void main_eos(GstElement *element, gpointer data)
        MSG_DEBUG("have eos, quitting ('%s')", GST_ELEMENT_NAME(element));

static void main_newpad (GstElement *decodebin, GstPad *pad, gboolean last,
        gpointer data)
        // link it to main
        gst_pad_link(pad, gst_element_get_pad(sink, "sink"));
        gst_bin_add(GST_BIN(main), sink);

static void main_state_change(GstElement *element, GstElementState oldstate,
        GstElementState state, gpointer data)
        MSG_DEBUG("main_state_change: called for '%s'", GST_ELEMENT_NAME(element));

ciao. Stefan
