Re: palybin http sources

here is my code:

    GstElement *pipeline = gst_pipeline_new("gst-test");
    GstElement *bin = gst_element_factory_make("playbin", "bin");
    GstElement *videosink = gst_element_factory_make("fakesink", "videosink");
    GstElement *audiosink = gst_element_factory_make("fakesink", "audiosink");
    if(!pipeline || !bin || !videosink || !audiosink)
        return false;
    g_object_set(G_OBJECT(bin), "video-sink", videosink, NULL);
    g_object_set(G_OBJECT(bin), "audio-sink", audiosink, NULL);
    if(!gst_bin_add(GST_BIN(pipeline), bin))
        return false;
    g_object_set(G_OBJECT(bin), "uri", buf, NULL);
    GstBus *bus;
    bus = gst_pipeline_get_bus(GST_PIPELINE(pipeline));
    gst_bus_add_signal_watch(bus);
    gst_bus_add_watch(bus, bus_test, NULL);
    gst_object_unref(bus);
    gst_element_set_state(pipeline, GST_STATE_PAUSED);
    g_loop = g_main_loop_new(NULL, FALSE);
    g_main_loop_run(g_loop);

In my bus_test handler, I checked for STATE CHANGED messages. For File sources, usually after about 4 STATE CHANGED messages, the state is changed from READY TO PAUSED. However with HTTP sources, the source never changes from READY.

You should also check the return value of _set_state() for FAILURE
and/or check for ERROR messages on the bus. Do you get any error
messages?

Re: palybin http sources

The return of set state is GST_STATE_CHANGE_ASYNC, and I do not get any error messages or any other type of message besides STATE_CHANGE.

I just receive 4 state change messages saying the oldstate was 1 (NULL) and new state is 2 (READY). After these 4 state messages, I receive a GStreamer-CRITICAL **: gst_bus_source_dispatch: assertion message !=NULL failed. message. I am not sure where this is coming from as it does not happen with file sources.

Re: palybin http sources

In reply to this post by Tim-Philipp Müller-2

Hello,
I fixed this problem by not adding playbin to another pipeline and just using playbin as the pipeline itself. Weird, but it works now.
