Hi Refer to <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-identity.html">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-identity.html</a> and to <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/section-data-spoof.html">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/section-data-spoof.html</a> The thing that you are talking about is "grab data from the pipeline to your app". You can take example from the identity element there: (the signal_handoff property) <a href="http://webcvs.freedesktop.org/gstreamer/gstreamer/plugins/elements/gstidentity.c?revision=1.124&view=markup">http://webcvs.freedesktop.org/gstreamer/gstreamer/plugins/elements/gstidentity.c?revision=1.124&view=markup</a> Sincerely Julien <div>2008/4/14, AlannY <<a href="mailto:alanny@starlink.ru">alanny@starlink.ru</a>>:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I'm writting an app and GStreamer plugin. Plugin reads data and *attention* pass data to my application. So, I have a one question: how to transmit data from my plugin to my app? I mean, i have a _chain() function in plugin and some GstBuffer in it. I want to tell my application (which already runs and loaded plugin) to do some things with that GstBuffer. Which way is best? To use GLib properties, or may be you already have a better way? If you can't understand my english - just skip this letter ;-) Thank you. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
