It's just that I wanted to test if I culd replace one of the request by a always pad, but it just complicates the task.

Otherwise, how every pad know all pads are data ready?<br>   When only one pad exist, one buffer can drive you process function. If another pad is created, the GstCollectPadsFunction will wait both pads are data ready, then call process function: collect.<br> <br><br><div class="gmail_quote">2008/7/3 Albert Costa <<a rel="nofollow" ymailto="mailto:costa_albert@yahoo.fr" target="_blank" href="mailto:costa_albert@yahoo.fr">costa_albert@yahoo.fr</a>>:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><div>Hi,<br>I'd like to write a plugin that has both GST_PAD_ALWAYS (would be type 'video/x-raw-rgb' for ex) and GST_PAD_REQUEST sink pads ("any" type, receiving possibly data from my own other plugins upstreams). I am able to create the 'always' pad on init, and the others through a request_pad function.<br> But how can I get buffers from all of them synchronously? 'always' pad would usually be handled by a chain() function, whereas the 'request' pads are handled through the GstCollectPadsFunction... Is there a way to mix all of that, or is it not possible?<br> Currently, I have found a workaround by setting my 'always' pad as a 'request' pad as well (then I just create the pad using the right template name when I link elements), but I feel this is a bit clumsy...<br> <br>If anyone has already tried something similar, help would be appreciated,<br>Regards,<br>Al<br></div></div><div class="WgoR0d"><br> <hr size="1"> Envoyé avec <a rel="nofollow" target="_blank" href="http://us.rd.yahoo.com/mailuk/taglines/isp/control/*http://us.rd.yahoo.com/evt=52423/*http://fr.docs.yahoo.com/mail/overview/index.html">Yahoo!
