Sorry If I don't understand but:<br><br>This error appears constantly if I launch the pipeline with gst-launch on this way:<br>gst-launch gnomevfssrc name="camsrc" do-timestamp=true location="<a href="http://server/">http://server/</a>" ! multipartdemux ! jpegdec ! \<br> timeoverlay valign="bottom" text="Frame Time" shaded-background=true ! \<br> clockoverlay text="clock time:" shaded-background=true ! ffmpegcolorspace ! \<br>ximagesink force-aspect-ratio=true<br><br>The error also appears with the python app that uses the same pipeline. I use  gst.parse_launch() to construct the pipeline. I also re-read the manpage for gst-launch and gst_parse_launch() and I did not notice any special way to give string parameters to elements other than the one it's being used. Besides that I am not passing any kind of number parameter to the elements of the pipeline, I am just passing string parameters. <br> <br>That's why I am confused. The app runs very well, but the messages can be annoying.<br><br>Any clues?<br><br><br><br><div class="gmail_quote">2008/12/9 sudarshan bisht <span dir="ltr"><<a href="mailto:bisht.sudarshan@gmail.com">bisht.sudarshan@gmail.com</a>></span><br> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div>Hi ,</div> <div>     You are doing something wrong while setting properties of elements , check them again and see what is the correct format of setting them (check for int, float, boolean etc).  <br><br></div><div><div></div><div class="Wj3C7c"> <div class="gmail_quote">On Wed, Dec 10, 2008 at 8:44 AM, Noe Nieto <span dir="ltr"><<a href="mailto:tzicatl@gmail.com" target="_blank">tzicatl@gmail.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0px 0px 0px 0.8ex; padding-left: 1ex;">Nice mission..

The last parameter denom can't be negative, that's why you got these warning messages.<br> <br>    So your mission is to find out where these messages come from. After that, you can tell why these messages occur. I also got these warnings several times and finally I find out the denom which I passed to gst_util_uint64_scale_int will be -1 when the playing is reaching EOS. So I add a "if" logic in the code and solved this problem.<br> <br>Eric Zhang<br><br> <div class="gmail_quote">2008/12/10 Noe Nieto <span dir="ltr"><<a href="mailto:tzicatl@gmail.com" target="_blank">tzicatl@gmail.com</a>></span><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></div> <div>I am working with this pipeline:<br>gnomevfssrc name="camsrc" do-timestamp=true location="%s" ! multipartdemux ! jpegdec ! \<br>timeoverlay valign="bottom" text="Frame Time" shaded-background=true ! \<br> clockoverlay text="clock time:" shaded-background=true ! ffmpegcolorspace ! \<br>ximagesink force-aspect-ratio="true"<br><br>When I run it there is a lot of messages printed in the console and they look like this:<br> <br>GStreamer-CRITICAL **: gst_util_uint64_scale_int: assertion `denom > 0' failed<br><br>This happens when I run the pipeline either with gst-launch or a specifically designed python app. The question is: Why do I keep getting this messages on the console?<br> <br><br>I hope someone can give some advice.<br><font color="#888888">Noe.<br></font><br></div></div>------------------------------------------------------------------------------<br>SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.<br> The future of the web can't happen without you.  Join us at MIX09 to help<br>pave the way to the Next Web now.
