Hi, thank you for the hint with the dot output. There I could see that the max buffer property of the the app sink has not been set correctly. After setting it correct all works fine. <table width=100%> <tr valign=top> <td width=41%>Marco Ballesio/ ( Gesendet von: gstreamer-devel-bounces+steffen.roeber=hella.com@lists.freedesktop.org 09.09.2011 15:08 <table border> <tr valign=top> <td bgcolor=white> <div align=center>Bitte antworten an Discussion of the development of and with GStreamer        <gstreamer-devel@lists.freedesktop.org></div></table> <td width=58%> <table width=100%> <tr valign=top> <td> <div align=right>An</div> <td>Discussion of the development of and with GStreamer <gstreamer-devel@lists.freedesktop.org> <tr valign=top> <td> <div align=right>Kopie</div> <td> <tr valign=top> <td> <div align=right>Thema</div> <td>Re: pipeline memory consumption</table> <table> <tr valign=top> <td> <td></table> </table> <tt>Hi, there may be many reasons for the increased memory size, some of which may even be fully legitimate depending on the system you're using and what you're playing. Indeed there's always room for bugs ;). Some questions below to help the community helping you ;).

See here: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-appsink.html#gst-app-sink-pull-buffer Are you consuming buffers fast enough?

Might it be that your system has an outrageous quantity of memory and that size is used for filesystem caching? > If I delete the pipeline all memory is freed. Who does take this memory? You could be interested in dumping the pipeline topology on a dot file: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstInfo.html#GST-DEBUG-BIN-TO-DOT-FILE:CAPS and verifying all the queues there are reasonably limited in length and size. It would also be interesting to know which decoders you're using and if any custom elements are used. I hope this will help.
