Hi Sudarshan,<br><br>I did not had the time to hack on this for a while, but finally I changed the pipeline to this:<br><br>gst-launch-0.10 -v gnomevfssrc location=$CAMERA ! mutipartdemux !  ffdec_mjpeg ! clockoverlay text="Camera 1" ! ffmpegcolorspace !   ximagesink <br><br>The video still freezes. I still don't know why, even if the caps says that the video is at 25fps. If I try to close the window, gst-launch does not terminate the execution of the pipeline, I have to hit Ctrl-C to re-gain control over the console.<br> <br><br><br>Any idea?<br><br><br><br><div class="gmail_quote">2008/10/5 sudarshan bisht <span dir="ltr"><<a href="mailto:bisht.sudarshan@gmail.com">bisht.sudarshan@gmail.com</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div dir="ltr"><div>Hi Noe ,</div> <div>             As you are using decodebin here as a decoder element so what is does is on the basis of input file it selects the decoder , here in your case it is selecting jpegdec(see red line in your log) , that means it will decode only one frame of data . </div> <div>            To fix this problem you can use ffdec_mjpeg element which is there in ffmpeg package. </div><div><div></div><div class="Wj3C7c"> <div>  </div> <div>       <br><br></div> <div class="gmail_quote">On Sat, Oct 4, 2008 at 6:06 AM, Noe Nieto <span dir="ltr"><<a href="mailto:tzicatl@gmail.com" target="_blank">tzicatl@gmail.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0px 0px 0px 0.8ex; padding-left: 1ex;"> <div dir="ltr">Thanks Sudarshan<br><br>Now I've changed the pipeline to this:<br>gst-launch-0.10 -v gnomevfssrc location=$CAMERA ! decodebin ! clockoverlay text="Camera 1" ! ffmpegcolorspace !  videoscale !  ximagesink force-aspect-ratio="true"<br> <br>But when I run the pipeline there is no video, it's only an still image with the clock time overlaid, but it is not moving.<br><br>What is the problem?
