How to know which all elements are used in the gstreamer pipeline which is playing audio/video. gst-inspect shows the no of all elements in gst registry Is there any command that tell the no and name of elements that are actively being used in gstreamer pipeline which is getting played on the device.</pre> </blockquote> One of the technique is to dump the graph in the form of a dot file (graphiz). If you are using your own program, you need to call <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> GST_DEBUG_BIN_TO_DOT_FILE() (or _WITH_TS() version if you want the file to have timestamp). If you using gst-launch-1.0 this is already handled for you. Then to enabled the dumps, you need to set GST_DEBUG_DUMP_DOT_DIR= to the path where you want the files to be created. This will give you dot file that you can compile into SVG or PNG: dot -Tsvg my.dot > my.svg dot -Tpng my.dot > my.png cheers, Nicolas </body> </html>
