how to get video duration

[kilamski]

Thank you for the feedback Nicolas,

i finally  managed to do it with a code that  is similar to the one you
attached.
Here is it is for completeness:

int get_ts_file_duration(char *path)
{
    GstDiscoverer *discoverer;
    GError *err = NULL;
    gchar *uri;
    unsigned long duration;

    uri = gst_filename_to_uri (path, &err);
    if (err)
    {
        g_print ("Error in gst_filename_to_uri(). file: %s: %s\n", path,
err->message);
        g_error_free (err);
        return -1;
    }

    /* Initialize GStreamer */
    gst_init (NULL, NULL);

    /* Instantiate the Discoverer */
    discoverer = gst_discoverer_new (1 * GST_SECOND, &err);
    if (!discoverer)
    {
        g_print ("Error creating discoverer instance: %s\n", err->message);
        g_error_free (err);
        return -1;
    }

    GstDiscovererInfo *info = gst_discoverer_discover_uri(discoverer, uri,
&err);
    if (err)
    {
        g_print ("Seems file: %s is brocken: %s\n", uri,  err->message);
        g_error_free (err);
        return -1;
    }

    /* If we got no error, show the retrieved information */
    duration = gst_discoverer_info_get_duration (info);
    duration /= 1000000000;//duration is in nanoseconds

    /* Free resources */
    g_object_unref (discoverer);
    gst_discoverer_info_unref(info);
    g_free(uri);

    return (int)duration;
}
