All 1000 files are created. pngdec which I use in the video creation pipeline does not have a property snapshot. Aslo, judging from the execution time, I have the impression that all images run through the pipeline somehow. </blockquote><div> Sorry, misread your launchline. You need to provide a framerate to pngdec, otherwise it will assume it is a single image decoding and push EOS right after the first frame. Something like this should work: gst-launch multifilesrc location=/tmp/test%05d.png caps="image/png, framerate=25/1" ! pngdec ! ffmpegcolorspace ! autovideosink </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Norbert <div class="im"> On 10/17/2010 06:28 AM, <a href="mailto:thiagossantos@gmail.com">thiagossantos@gmail.com</a> wrote: > > > On Wed, Oct 13, 2010 at 8:41 PM, Norbert Stuhrmann </div><div><div></div><div class="h5">> <<a href="mailto:stuhrman@stanford.edu">stuhrman@stanford.edu</a> <mailto:<a href="mailto:stuhrman@stanford.edu">stuhrman@stanford.edu</a>>> wrote: > > Hi, > > another person was able to confirm this on another machine.
