How to handle "Could not determine type of stream" in GstApp?

[jmz]

Hi,

I have a program using "appsrc ! decodebin ! ... ! appsink" as a pipeline.

The appsrc pushes data within buf and EOS to its source pad. The appsink
handles data until EOS has been received.

    // appsrc pushes data
    gst_app_src_push_buffer (GST_APP_SRC (app->src), buf);
    gst_app_src_end_of_stream (GST_APP_SRC (app->src));

    // blocking here if could not determine type of stream

    while (!gst_app_sink_is_eos(GST_APP_SINK(sink))) {
        // appsink handles data
    }

The program is blocked if the data feeded by appsrc can't be decoded. The
debugging messages are shown as follows.

0:00:00.022883965 25934       0xb5e720 INFO                 basesrc

gsttask.c:300:gst_task_func:<source:src> Task going to paused

I have a bus message handler which can get GST_MESSAGE_ERROR on the error.
However, I can't stop the program using g_main_loop_quit() in "case
GST_MESSAGE_ERROR" because I don't use a GLib event loop.

How can I stop the program on the "Could not determine type of stream"?

Best Regards
