Hi,<br>Thank you for your reply.<br>In this pipeline pull element is in middle.<br>I added activate_pull in pullreader plugin.<br>i am using chain function in pushreader plugin.<br>where should i use activate_push.<br><br> Thanks<br>Nagaraju K<br><br><div class="gmail_quote">On Tue, Jul 28, 2009 at 5:03 AM, pritesh kumar <span dir="ltr"><<a href="mailto:pritesh.kumar2@gmail.com">pritesh.kumar2@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div>hi ,</div> <div>i cant predict the exact reason, but according to me the pipeline u r trying to implement is not correct approach.</div> <div> </div> <div>the pull elements should be most upstream , otherwise u have to handle the pad activation functions properly. activate_push () , activate_pull().</div> <div> </div> <div> </div> <div>Alternatively,</div> <div> </div> <div>the pipeline can be alsasrc ! pushreader ! alsasink </div> <div> </div> <div>where the pushreader is a push element .</div> <div> </div> <div>whereas in push reader u can have async data queue , which will receive data from alsasrc and on a separate thread push data to alsasink.</div> <div> </div> <div> </div> <div>let the push reader be a completey push element.</div> <div> </div> <div>or may be this approach alsasrc ! push reader ! queue ! alsasink </div> <div> </div> <div> </div> <div>regards</div> <div>antwan rockamora</div><div><div></div><div class="h5"> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> <br><br></div> <div class="gmail_quote">On Tue, Jul 28, 2009 at 12:59 PM, raju03e <span dir="ltr"><<a href="mailto:raju01e@gmail.com" target="_blank">raju01e@gmail.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0px 0px 0px 0.8ex; padding-left: 1ex;"><br>Hi,<br><br>I am a newbee to gstreamer.
