How to add audio part in a pipeline dynamically?

[cfd new]

I tried to add audio part in a rtsp pipeline dynamically withauto audio_bin = gst_parse_bin_from_description( "queue ! decodebin ! audioconvert ! autoaudiosink", TRUE );My problem is I do not want to handle different audio forms manually. Therefore, decodebin is applied here. However, audio_bin can not be linked to the pipeline. Does the pad of decodebin need to be handled?
