You can try setting "max-size-buffers" property in queue element to some number ( optimum ) . <div class="gmail_quote">On Wed, Mar 3, 2010 at 2:57 PM, Sedji Gaouaou <<a href="mailto:sedji.gaouaou@atmel.com">sedji.gaouaou@atmel.com</a>> wrote: <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Hello, I am currently working on a gstreamer plugin for the atmel at91sam9m10(source can be found here: <a href="http://www.at91.com/linux4sam/bin/view/Linux4SAM/SAM9M10Gstreamer" target="_blank">http://www.at91.com/linux4sam/bin/view/Linux4SAM/SAM9M10Gstreamer</a>). It embeds a video decoder, and I am trying to make it works. Currently I am testing it doing: gst-launch filesrc location= mnt/video/AVI/MPEG4/myfile.avi ! avidemux name=demux demux.video_00 ! queue ! x170 output=RGB16 inbuf-thresh=0000 output_width=480 output_height=240 ! ximagesink display=:0.0 It works for a while, but at some point I have this error: WARNING: from element /GstPipeline:pipeline0/GstXImageSink:ximagesink0: A lot of buffers are being dropped. Additional debug info: gstbasesink.c(2572): gst_base_sink_is_too_late (): /GstPipeline:pipeline0/GstXImageSink:ximagesink0: There may be a timestamping problem, or this computer is too slow. I am using the gstreamer_0.10.25. I have noticed that this message comes from the gstbasesink.c, and I also noticed that if I change the timestamp of my decoded frame to "GST_CLOCK_TIME_NONE", then I don't see the problem anymore(but of course the file is played in fast forward...) I am quite stuck with this issue, so any idea will be great!!
