[gst-devel] Getting cracked sound when encoding from audiotestsrc -> filesink

[Guilherme]

Hi all.

I am getting a cracked noise when running the following pipeline:

[audiotestsrc] ! [wavenc] ! [filesrc]

I fighting 4 weeks and Ive tried everything that I know to solve that... 
without success ;o(

That's the code:

#include<gst/gst.h>
#include<glib.h>

static gboolean bus_call(GstBus *bus, GstMessage *msg, gpointer data);

int main(int argc, char *argv[])
{
    GMainLoop *loop;
   
    GstElement *pipeline, *source, *audioconvert, *wavenc, *filesink;
    GstBus *bus;
   
    gst_init(&argc, &argv);
   
    loop = g_main_loop_new (NULL, FALSE);
   
    /*creating elements*/
    pipeline     = gst_pipeline_new ("audio-player");
    source       = gst_element_factory_make ("audiotestsrc", "file-source");
    //audioconvert = gst_element_factory_make ("audioconvert", 
"audio-conversor");
    wavenc       = gst_element_factory_make ("wavenc",       "wave-enc");
    filesink     = gst_element_factory_make ("filesink",     
"audio-output");
   
    if (!pipeline || !source || !audioconvert|| !wavenc || !filesink) {
        g_printerr ("One element could not be created. Exiting.\n");
        return -1;
    }
   
    g_object_set (G_OBJECT (filesink), "location", "foo.wav", NULL);
   
    /*set-up the pipeline*/
   
    /*message handler*/
    bus =  gst_pipeline_get_bus (GST_PIPELINE (pipeline));
    gst_bus_add_watch (bus, bus_call, loop);   
    gst_object_unref (bus);
   
    /*colocar todos elementos na pipeline*/
    gst_bin_add_many (GST_BIN (pipeline), source, wavenc, filesink, NULL);
                           
    /*Linkar elementos*/
    //gst_element_link ();
    gst_element_link_many (source, wavenc, filesink, NULL);
    //g_signal_connect (demuxer, "pad-added", G_CALLBACK (on_pad_added), 
decoder);
   
    /* set pipeline playing status */
    g_print ("Running...\n");
    gst_element_set_state (pipeline, GST_STATE_PLAYING);
   
    /*iterate*/
    g_print ("Recording\n");
    g_main_loop_run (loop);
   
    /* Out of the main loop, clean up nicely */
   g_print ("Returned, stopping playback\n");
   gst_element_set_state (pipeline, GST_STATE_NULL);

   g_print ("Deleting pipeline\n");
   gst_object_unref (GST_OBJECT (pipeline));

  return 0;
}

static gboolean bus_call(GstBus *bus, GstMessage *msg, gpointer data) {

    return TRUE;
}

Does anyone could give to me some help??

Thanks!

Tks!
