<html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> Hello Gstreamer mailing-list, I'm trying to build a jingle program (something like <a href="http://www.jinglepalette.com/">Jingle pallet</a>) using Gstreamermm and Gtkmm. In the process of doing this, I ran into some problems. Because in this program, sounds need to be played when the user presses a button. I got that working. The thing is when I try to play multiple sounds. Here is how I think it should be done (excuse my poor 'image'): SoundBin1 ______________________________________________________________________ fileSrc -- > decoderBin -- > converter -- > resampler -- > capsFilter -- | | SoundBin2 |--> liveadder -- > autosink ____________________________________________________________________ | fileSrc -- > decoderBin -- > converter -- > resampler -- > capsFilter -- This of course works fine. But when the pipeline is started both soundbins start playing. So what I tried doing is the following: <ol> <li>Create all elements en add them to the pipeline.</li> <li>Link all elements as described above.</li> <li>Block (using the src pad of soundbin 1 and 2) with set_blocked(true);.</li> </ol> When a button is pressed, the program will unblock the corresponding soundbin pad, seek to 0 and start the main pipeline. Now the real problem: When the second button is clicked, it will start playing at the time that has already elapsed. So if soundbin 1 has been playing for 5 seconds and soundbin 2 is started, soundbin 2 will begin playing at 5 seconds. So what I really would like to know is what I am doing wrong, or if it is even possible to do this with Gstreamer. I searched around on the internet quite a bit but I couldn’t find a thing on how to do this. Thanks in advance. Regards, Martijn </body> </html>
