It is against the philosophy of GStreamer, I suggest rather to create two sources (audio and video) and then mux them using desired muxer, or use two sinks if you want to display them.<div> </div><div>m. <div class="gmail_quote"> 2012/7/23 gem-tos <<a href="mailto:postolovicmickael@msn.com" target="_blank">postolovicmickael@msn.com</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hello all, firstly, excuse me for my poor english. I need to write a source element with at least 2 source pads (audio and video) I started with a customized version of videotestsrc. I am able to get frame from my compression card and display the video in autovideosink element but now I need to add audio. I saw that I can't have multiple src pads with BaseSrc class. So my question is, can someone help me to start writing a new source element with 2 src pads or give me a starting point ?
