OK, then try a queue2 after fileasrc , they normally buffer 2MB but you can increase it. <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-queue2.html">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-queue2.html</a> Mike Mitchell <div class="gmail_quote">On Fri, Oct 7, 2011 at 1:47 AM, Andreas Rödig <<a href="mailto:a.roedig@null821.de">a.roedig@null821.de</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> Hi Mike, thanks for your answer. My Problem is: Reading from harddisk and decoding are fast enough (atom d525 and ion2 via vdpau). But sometimes i have some little harddisk actions. And only at this time i see the video bucking. Thats why i think that a read buffer is good for me.

You could make your own pipline which would start with filesrc, but that has no buffer element either. <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-filesrc.html" target="_blank">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-filesrc.html</a> If you can't get the file off your disk fast enough, your machine is just too slow. That is hard to believe that it is a real problem unless it is raw with no compression at all. You may need to transcode it first to play on a slower machine. *Mike Mitchell* On Fri, Oct 7, 2011 at 12:56 AM, Andreas Rödig <<a href="mailto:a.roedig@null821.de" target="_blank">a.roedig@null821.de</a> <mailto:<a href="mailto:a.roedig@null821.de" target="_blank">a.roedig@null821.de</a>>> wrote: Hello, i need to buffer some video which is playing from harddisk.
