<div dir="ltr">Tim, I followed your suggestions ... got playbin and used its volume property. I also created a separate thread for running the gst loop and checking bus messages and so far things are good. Thanks for your help.

Does this allow volume changing when the pipeline is playing .. if so how would you do that ? <div class="gmail_quote">On Mon, Sep 1, 2008 at 3:05 AM, Tim-Philipp Müller <<a href="mailto:t.i.m@zen.co.uk" target="_blank">t.i.m@zen.co.uk</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div>On Thu, 2008-08-28 at 13:08 -0500, Raj Swaminathan wrote: Hi, > I am new to Glib programming and gstreamer.

The GStreamer mixer interface (GstMixer) is to control hardware mixer levels, you usually don't want that in a playback application. It's also not very nice to use. If you don't use playbin, add a volume element to your pipeline (alternatively: audiosinks which support stream volumes will also have a "volume" property). <div> > 2) When designing the media player, whats the best way to accept user > input.

All you need to do is check the pipeline's/playbin's GstBus for messages (errors, tags, state changes) from time to time.
