Souphttpsrc and playbin

Hi,

I am trying to stream an Internet Radio Channel with playbin. I am going through a proxy and can use gst-launch in this way to successfully play the station:

gst-launch souphttpsrc proxy=http://proxyURL location=http://myIRadio.com. ! mad ! alsasink

I do not need to use gst-launch and am actually building my own software media player ....

When i do not setup proxy but just run my mediaplayer with playbin, I just wait on an endless loop and get the following debug message on cancelling..
gstsouphttpsrc.c(683): gst_soup_http_src_finished_cb(): /play/source
libsoup status code 1
Error: Cancelled

So playbin is trying to use souphttpsrc but Im assuming the error is becoz the proxy is not set .....
Can someone plz suggest how to set the proxy property with souphttpsrc and still use playbin v1 ?

Thanks,
raj

Re: Souphttpsrc and playbin

Hi, Raj:

    That's easy. First, connect `notify::source' signal of playbin:

// connect signal
g_signal_connect(G_OBJECT(playbin), "notify::source", G_CALLBACK(cb_playbin_notify_source), NULL);

Then the callback function(I am working on rtsp recently so the example source below is a rtspsrc. In your program, this should be souphttpsrc):

static void cb_playbin_notify_source(GObject *obj, GParamSpec *param, gpointer u_data)
{
    // check whether this is rtsp source
    gchar *objname = GST_OBJECT_NAME(obj);
    g_message("objname is %s", objname);

    // check whether has a `protocols' property
    if (g_object_class_find_property(G_OBJECT_GET_CLASS(obj), "source")) {
        GObject *source_element;
        g_object_get(obj, "source", &source_element, NULL);
        if (g_object_class_find_property(G_OBJECT_GET_CLASS(source_element), "protocols")) {
            g_object_set(source_element, "protocols", 1, NULL);
        }
        g_object_unref(source_element);
    }
}

One possibility already mentioned by Eric is to connect to the
notify::source signal and set up the source in the callback. This is the
recommended way of configuring playbin sources (also for things like
"device" properties and the like).

In your case you could also just set the http_proxy environment variable
(g_set_env) - if you're lucky souphttpsrc will take that into account
and configure itself accordingly.

Cheers
