Hi,<br><br>I'm not an expert of Ruby, btw there are a few sanity checks you may run (see below)..<br><br><div class="gmail_quote">On Fri, May 20, 2011 at 11:57 PM, Matt McIntyre <span dir="ltr"><<a href="mailto:matt@stillcompiling.com">matt@stillcompiling.com</a>></span> wrote:<br>

I'm writing a program using the ruby-gnome2 gstreamer bindings that captures video (v4l) and audio (standard soundcard), displays the video onscreen, loops the audio back out for monitoring, and records to disk using avi/wav. I'll be glad to provide the code, but in consideration of everyone's time I'll provide the gstreamer pipeline I'm first since I'm sure its something simple I'm not doing right.<div>
<br></div><div>My pipeline is separated into several bins and looks like this:</div><div><br></div><div>AudioBin: (source ghost pad to the tee src)</div><div><br></div><div>autoaudiosrc ! audio/x-raw-int ! level ! tee name=audiotee</div>
<div>audiotee ! autoaudiosink</div><div><br></div><div>VideoBin: (source ghost pad to the tee src)</div><div><br></div><div>v4l2src ! video/x-raw-yuv, format=(fourcc)YUY2, framerate=(fraction)30000/1001, width=(int)720, height=(int)480 ! videorate ! tee name=videotee</div>
<div>videotee ! xvimagesink<br clear="all"></div></blockquote><div><br>here you're dealing with raw 720x480 YUY2 @ 30fps..
