Is my approach is correct ? </div>It depends on the component. For MP3 decoding there's already a gst-openmax wrapper, so the only thing you need to do is specify your component name: omx_mp3dec component-name="OMX.myvendor.mycomponentname"</blockquote></div><div>      Here i am able to mapped by decoder component to ST component.      thanks for your suggestion. </div><div class="Ih2E3d"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div> > if yes, > Up to now i am able to map Mp3 Decoder component.

It's quite possible that they are not working.

In the above link which version of gst-openmax is used ? Because i am using gst-openmax-0.10.0.4.lib.     In that lib i am not having reference lines you mentioned in gstomx_base_sink.c file. I am confused with your file.     I have some questions here.       1.like Mp3 component,  can i replace the "OMX.st.alsa.alsasink" with my Render component.          If Not how to load my render component ?          if yes i am unable to render the decoder output on my sound card. Please clarify me how sink component is communicating          with Bellagio component.       If you required, i can provide my debug logs </div><div class="Ih2E3d"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div> > 2.

There's a 'tunneling' branch pending in the github repository to use OMX_SetupTunnel, but it should not be required to get your code working. What? omapzoom?</blockquote></div><div>     Thanks for your suggestion. for a while i am not looking in to the OMX_SetupTunnel concepts.      omapzoom is kind off source tree which is also working on OMX_SetupTunnel issues i think.      But leave this for a moment. </div></div> Please replay me back with your valuable suggestions. -- Thanks & Regards Sriramamurti Kommanapalli INDIA </div>
