<div>Hi ,</div> <div>      As far as my understand about your aim is that you want to print time on a jpeg image and want to display the same  . </div> <div>I tried the same thing by just replacing gnomevfssrc  with filesrc , and i also got the same problem . </div> <div>     This is happening because of  "received non-Time new segment event on video input" in both timeoverlay and clockoverlay elements.  And i guess why  this is happening because of the data processing  is very fast compare to event propagation since only one frame of data is there .    </div> <div>    If you try same thing for a video file , you will not get this problem. </div> <div>     </div> <div> </div> <div>     <br><br></div> <div class="gmail_quote">On Wed, Dec 10, 2008 at 11:02 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="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">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/" target="_blank">http://server/</a>" ! multipartdemux ! jpegdec ! \ <div><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></div>The error also appears with the python app that uses the same pipeline.

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.
