Hi Tom: We were trying to do something similar to what you explain here (search for a mail in the list with subject="Switching between different audio streams over RTSP stream"). After some trials with input-selector, we have tried using an "adder" with better results. Maybe this is valid for you too. Regards, Alex <div class="gmail_quote">On Sat, Jan 23, 2010 at 2:05 AM, GT6 <<a href="mailto:gt6@gmx.net">gt6@gmx.net</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hello there, I'm trying to use input-selector to switch between two different sources, while not actually stopping the stream. In my specific use case, I have one audiotestsrc wave=4, which is just silence, and a "filesrc | decodebin". These should be switched by the input-selector. From there, the stream gets vorbisencoded and sent to a multifdsink (which is then served as a file by my app for people to connect to). The purpose of this is that clients can connect to the file and listen to it - as in a streaming radio, and even if nothing is playing, the stream will still be stable and not cut off. But any of this doesn't really matter for the basics: In this example script, which can be run as is (maybe change the sink type from osssink to alsasink or whatever you need), there's a low beep and a high beep. What do I have to do to switch from the low beep to the high beep? No matter how I arrange the block() and switch() emissions, the second beep never gets through. Pastebin: <a href="http://pastie.org/790685" target="_blank">http://pastie.org/790685</a> and it's also attached. Could someone please be so kind and explain to me in what order the block/switch stuff needs to be called for this to work? Thanks a lot.
