I use playbin and decodebin. The technical description: I initialize first the gstreamer with gst_init( &argc, &argv ). It works fine. After this i create a new pipeline with function gstt_pipeline_new( "name" ); All ok. Now i create an output binary with convert, resample, volume and sink elements. Thats fine. So i add bin, link and add pad to this.     GstElement *outputConvert   = gst_element_factory_make ("audioconvert", "audioconvert" );     GstElement *outputResample  = gst_element_factory_make ("audioresample", "audioresample" );     GstElement *outputVolume    = gst_element_factory_make ("volume", "volume" );     GstElement *outputSink      = PSGstHelper::audioSink(); // gives me the correct audio from systemx     gst_bin_add_many( GST_BIN( m_gstBinary[ OUTPUT ] ), outputConvert, outputResample, outputVolume, outputSink, NULL );     gst_element_link_many( outputConvert, outputResample, outputVolume, outputSink, NULL );     GstPad *outputPad = gst_element_get_static_pad( outputConvert, "sink" );     gst_element_add_pad( m_gstBinary[ OUTPUT ], gst_ghost_pad_new( "sink", outputPad ) );     gst_object_unref( outputPad );     gst_object_ref( m_gstBinary[ OUTPUT ] );     After creating this binary, i create a new binary for "filesrc"           GstElement *fileSource    = gst_element_factory_make( "filesrc", "filesrc" );     GstElement *fileDecoder   = gst_element_factory_make( "decodebin", "decodebin" );     GstElement *fileIdentity  = gst_element_factory_make( "identity", "identity" );     if( fileSource && fileDecoder && fileIdentity) {       gst_bin_add_many( GST_BIN( m_gstBinary[ FILE ] ), fileSource, fileDecoder, fileIdentity, NULL );       gst_element_link_many( fileSource, fileDecoder, NULL );       g_signal_connect( G_OBJECT(fileDecoder), "new-decoded-pad", G_CALLBACK(gstPadLink), fileIdentity );       GstPad * pad = gst_element_get_static_pad (fileIdentity, "src");       gst_element_add_pad( m_gstBinary[ FILE ], gst_ghost_pad_new("src", pad) );       gst_object_unref(pad);       gst_object_ref( m_gstBinary[ FILE ] );       //g_timeout_add( 200, (GSourceFunc)gstQueryTimePosition, fileSource );     } After creating this binary, i create a new binary for "playbin"     GstElement *httpSource    = gst_element_factory_make( "playbin", "playbin" );     GstElement *httpDecoder   = gst_element_factory_make( "decodebin", "decodebin" );     GstElement *httpIdentity  = gst_element_factory_make( "identity", "identity" );     if( httpSource && httpDecoder && httpIdentity ) {       gst_bin_add_many( GST_BIN( m_gstBinary[ HTTP ] ), httpSource, httpDecoder, httpIdentity, NULL );       gst_element_link_many( httpSource, httpDecoder, httpIdentity, NULL );       g_signal_connect( G_OBJECT(httpDecoder), "new-decoded-pad", G_CALLBACK(gstPadLink), httpIdentity );       GstPad *httpPad = gst_element_get_static_pad( httpIdentity, "src" );       gst_element_add_pad( m_gstBinary[ HTTP ], gst_ghost_pad_new( "src", httpPad ) );       gst_object_unref( httpPad );       gst_object_ref( m_gstBinary[ HTTP ] );       g_timeout_add( 200, (GSourceFunc)gstQueryTimePosition, httpSource );     }   At end i set the state to ready:   gst_element_set_state( m_gstPipeline, GST_STATE_READY );   gst_element_get_state( m_gstPipeline, NULL, NULL, GST_CLOCK_TIME_NONE ); Everything fine, but my problem, if i play with m_gstBinary[ FILE ] works ok, but if i play with m_gstBinary[ HTTP ] is not working. My play function sets the state to GST_STATE_PLAYING on m_gstPipeline but i get GST_STATE_CHANGE_ASYNC every time. Before I play a source I change the m_gstPipeline to the correct m_gstBinary but if it is playing I set the state to GST_STATE_NULL:   m_gstPlayElement = m_gstBinary[ _binaries ];   gst_bin_add_many( GST_BIN(m_gstPipeline), m_gstPlayElement, m_gstBinary[ OUTPUT ], NULL);   gst_element_link_many( m_gstPlayElement, m_gstBinary[ OUTPUT ], NULL);   GstStateChangeReturn ret = gst_element_set_state( m_gstPipeline, GST_STATE_READY );   ret = gst_element_get_state( m_gstPipeline, NULL, NULL, GST_CLOCK_TIME_NONE );   Of course I catch the events from m_gstPipeline such as GST_MESSAGE_BUFFERING ... GST_MESSAGE_BUFFERING and so on. But I can't play the stream! Regards ChMaster <div class="signature"> -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!
