Hi Felipe,          Thanks for your gst-launch-0.10 suggestion. Now i am able to render my sink component also with this tool, and able to play audio from my sound card. I have few questions here. 1. Why same sink component i am unable to load from Totem Player application ?     Is it because of application or gst_openmax layer. 2. gst-launch-0.10 is command line tool. with this i am not able to debug the Gst_Openmax layer and my IL layer.    Is there any other tool available from sources ..? 3. Is there any openmax component for muxer, demuxer, clock kind of elements ? -- Thanks & Regards Sriramamurti Kommanapalli <div class="gmail_quote"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div>>          Still i am unable to load "OMX.st.alsa.alsasink" component with > gstreamer openmax layer like >          "OMX.st.audio_decoder.mp3.mad" component. > >          I am using top level application as totem player source packages. > providing  gstreamer openmax plug_in path also. > >          Like Mp3 component i am not able to get the handle for alsasink > component. </div>Have you tried to do something simpler? Like try only the mp3 decoder with the normal audio sink. Perhaps using gst-launch-0.10 instead of totem. -- Felipe Contreras </blockquote></div>
