Hi Cai,
Thanks for you response, I Will try out your suggestion of using the filtered link. Sorry there was some typoerror in my code what I shared. I did initialized the 'resmux' as capasity filter and used the conv not conv1. The cocde works for me for mp3 playback in its original settings. resample = gst_element_factory_make ("audioresample", "audio-resample"); conv = gst_element_factory_make ("audioconvert", "converter1");
resmux = gst_element_factory_make ("capsfilter", "filter"); caps = gst_caps_new_simple ("audio/x-raw-int", "width", G_TYPE_INT, 16, "depth", G_TYPE_INT, 16,
"rate", G_TYPE_INT, 22050, "channels",G_TYPE_INT, 2, NULL );
if (!musicPlayer.playPipeline || !source || !sink || !resample || !resmux || !caps || !conv) { g_print ("NO MEM Exiting.\n");
return 1; } /* we set the input filename to the source element */ g_object_set (G_OBJECT (source), "location", filePath, NULL);
demuxer = gst_element_factory_make ("id3demux", "id3-demuxer"); decoder = gst_element_factory_make ("mad", "mp3-decoder"); if (!demuxer || !decoder || !conv) { g_print ("NO MEM Exiting.\n"); return 1;

Hi ,
I Tried the suggestion provided for the by Cai. Thanks for the code Cai. It works something like this It only allows to playback the 22KHz S16LE audio.
What I was trying is to convert the any input format into a 22KHz S16LE so I can mux it with other stream of the same property and mux multiple streams using alsasink plug:dmix.
