GstCaps filter issue

[doon]

I trying to create filter using caps:
                GMainLoop *loop;
                GstElement *pipeline, *source, *demuxer, *decoder,  *typefind, *conv, *sink;;
                GstBus *bus;
                guint bus_watch_id;


                loop = g_main_loop_new(NULL, FALSE);

                pipeline = gst_pipeline_new ("audio-player");
                source   = gst_element_factory_make ("filesrc",       "file-source");
                typefind = gst_element_factory_make ("typefind", "typefinder");
                demuxer  = gst_element_factory_make ("oggdemux",      "ogg-demuxer");
                decoder  = gst_element_factory_make ("vorbisdec",     "vorbis-decoder");
                conv     = gst_element_factory_make ("audioconvert",  "converter");
                sink     = gst_element_factory_make ("autoaudiosink", "audio-output");

                if (!pipeline || !source || !demuxer || !decoder || !conv || !sink) {
                        g_printerr ("Не удалось создать один из элементов конвейера. Работа приложения завершена.\n");
                        return -1;
                }
                g_signal_connect (typefind, "have-type", G_CALLBACK (cb_typefound), loop);
                g_object_set(G_OBJECT(source), "location", name_of_file, NULL);

                bus = gst_pipeline_get_bus(GST_PIPELINE(pipeline));
                bus_watch_id = gst_bus_add_watch(bus, bus_call, loop);
                gst_object_unref(bus);

                gst_bin_add_many(GST_BIN(pipeline), source, typefind, demuxer, decoder, conv, sink, NULL);

                GstCaps *my_caps = gst_caps_new_simple ("audio/x-raw","rate", G_TYPE_INT, 384,NULL);


                gboolean test=false;
                test = gst_element_link_filtered(source,typefind, my_caps);
                test = gst_element_link(typefind, demuxer);
                test = gst_element_link_many(decoder, conv,sink, NULL);


                g_signal_connect(demuxer, "pad-added", G_CALLBACK(on_pad_added), decoder);
............

But get error:
Debug: gsttypefindelement.c(1169): gst_type_find_element_loop (): /GstPipeline:a
udio-player/GstTypeFindElement:typefinder:
stream stopped, reason not-linked

Var test == 1 after gst_element_link_filtered(source,typefind, my_caps);
      test == 0 after gst_element_link(typefind, demuxer);
      test == 1 after gst_element_link_many(decoder, conv,sink, NULL);
If I just change gst_element_link_filtered on gst_element_link all going ok and file plays.
What am I doing wrong?

Hi, 

You're setting a caps filter of type audio/x-raw between the filesource and the typefind element, but the demuxer you selected (oggdemux) does not support that on its sink pad.

What are you trying to do?

Cheers

Thanks for the response!
Yes, oggdemux really need audio/ogg on sink pad. Now I trying to link audioconvert to autoaudiosink with the same caps and with caps with "audio/ogg" type but still have same error.
I think I don't quite understand something, can you explain?

Hey 

If your objective is to have control over the audiorate, I would suggest modifying your code to implement a pipeline like this

filesrc ! oggmux ! vorbisdec ! audioconvert ! audiorate (or audioresample) ! audio/x-raw, rate=<desired_rate> ! autoaudiosink

and then set the desired rate on the audiorate/audioresample element. 

Cheers

Yes, oggdemux really need audio/ogg on sink pad. Now I trying to link
audioconvert to autoaudiosink with the same caps and with caps with
"audio/ogg" type but still have same error.

Thanks! But my preferred objective is to understand why I have this error and how I can correctly use caps in this case.
