demux/remux pipeline hangs when audio is added

[Carah Smith]

I got it working in the code now. Thank you both for your help! Below is
the working code in case anyone is curious or still struggling with this
issue. All error checking has been removed for conciseness. I didn't
include the helper functions or structure because they did not change all
that much.

int
main(int argc, char **argv)
{
    GstElement *source;
    GstElement *pipeline;
    GstElement *sink;
    GstElement *mux;
    GstElement *x264_enc;
    GstElement *a_convert;
    GstElement *v_convert;
    GstElement *aac_enc;
    struct custom_data data;
    GstElement *v_queue;
    GstElement *a_queue;
    GstBus     *bus;
    GstMessage *msg;
    gboolean terminate = FALSE;

    gst_init (&argc, &argv);

    source    = gst_element_factory_make("uridecodebin", "URI_decoder");
    v_convert = gst_element_factory_make("videoconvert", "video_converter");
    v_queue   = gst_element_factory_make("queue", "v_queue");
    a_queue   = gst_element_factory_make("queue", "a_queue");
    x264_enc  = gst_element_factory_make("x264enc", "h264_encoder");
    a_convert = gst_element_factory_make("audioconvert", "audio_converter");
    aac_enc   = gst_element_factory_make("faac", "aac_encoder");
    mux       = gst_element_factory_make("mpegtsmux", "muxer");
    sink      = gst_element_factory_make("hlssink", "hls_sink");

    data.video = v_queue;
    data.audio = a_queue;

    pipeline = gst_pipeline_new("test-pipeline");

    g_object_set(G_OBJECT(source), "uri", "file:///stream_1.ts", NULL);

    link_to_multiplexer(x264_enc, mux);
    link_to_multiplexer(aac_enc, mux);

    g_signal_connect(source, "pad-added", G_CALLBACK(on_pad_added), &data);

    gst_element_set_state(pipeline, GST_STATE_PLAYING);

    bus = gst_element_get_bus(pipeline);
    do
    {
        msg = gst_bus_timed_pop(bus, 0);

        if (msg != NULL)
        {
            switch (GST_MESSAGE_TYPE(msg))
            {
                case GST_MESSAGE_ERROR:

                    break;
                case GST_MESSAGE_STATE_CHANGED:
                    if (GST_MESSAGE_SRC(msg) == GST_OBJECT(pipeline))
                    {
                        GstState old_state, new_state, pending_state;

                        gst_message_parse_state_changed(msg, &old_state,
&new_state, &pending_state);
                        g_print("Pipeline state changed from %s to %s:\n",
                        gst_element_state_get_name(old_state),
gst_element_state_get_name(new_state));
                    }
                    break;
                default:
                break;
            }
            gst_message_unref(msg);
        }
    } while (!terminate);

    gst_object_unref(bus);
    gst_element_set_state(pipeline, GST_STATE_NULL);
    gst_object_unref(pipeline);

    return 0;
}
