<div dir="ltr">You have made an easy and common mistake. The GStreamer SDK is not associated with the GStreamer project, despite the name. I have never used the GStreamer SDK. I really don't know why it was created. You should look here -> <a href="http://gstreamer.freedesktop.org/">http://gstreamer.freedesktop.org/</a> for the latest documentation, source and binaries. And yes, GStreamer 1.0 is *NOT* compatible with GStreamer SDK. The SDK code is very old. </div><div class="gmail_extra"> <div class="gmail_quote">On Wed, Apr 8, 2015 at 12:39 AM, Sneha Murganoor <<a href="mailto:sneha.nie@gmail.com" target="_blank">sneha.nie@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Hi Sergio, </div><div>how to move to gstreamer-1.0?

Notice that this 'oggvorbisplayer' plugin is representative of the custom plugin someone has (personally) developed and therefore not part of the generically available plugins. You can find more info on how to write custom plugins in the Plugin Writers Guide <<a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/pwg/html/index.html" target="_blank">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/pwg/html/index.html</a>> . 2 - If you run gst-inspect without any additional argument it will print the list of available plugins on your system. Side note: You're reading the manual for 1.4.5 and yet you're using 0.1. I would recommend bumping it to the latest version.
