<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi Nikola or anyone else, In the end I will be working with named pipes with the video file being saved by gstreamer from the axis IP camera. When I make a named pipe using mkfifo test.gdp and then do: gst-launch-0.10 -e rtspsrc location=rtsp://root:pass@192.168.2.127/mpeg4/media.amp ! rtpmp4vdepay ! mpeg4videoparse ! gdppay ! filesink location=/tmp/test.gdp& and then playback with gst-launch-0.10 filesrc location=/tmp/test.gdp ! gdpdepay ! ffdec_mpeg4 ! xvimagesink it works perfectly with the camera bitrate set at 100kbps and I see the live video feed from the camera. With the camera set at 10kbps, it starts, and I see the gst-launch playback window with the vide feed but it updates extremely slow.  I see a message in the command line saying There may be a timestamping problem, or this computer is too slow. WARNING: from element /GstPipeline:pipeline0/<div id=":x7">GstXvImageSink:xvimagesink0: A lot of buffers are being dropped. Additional debug info: gstbasesink.c(2686): gst_base_sink_is_too_late (): /GstPipeline:pipeline0/GstXvImageSink:xvimagesink0: There may be a timestamping problem, or this computer is too slow.</div> Does anyone have advice on additional parameters I may need to use?  Unfortunately I have a need to work at 10kbps.  At this low of bitrate I have problems with mplayer and mencoder.  However even at 10kbps, the following works fine gst-launch playbin uri=rtsp://192.168.0.90/mpeg4/media.amp Thanks Tom --- On Sat, 4/9/11, Tom Hendrick <sdtom182@yahoo.com> wrote: <blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> From: Tom Hendrick <sdtom182@yahoo.com> Subject: Re: Help with Gstreamer and RTSP with Axis Camera To: lists@svrinformatica.it, "Discussion of the development of and with GStreamer" <gstreamer-devel@lists.freedesktop.org> Date: Saturday, April 9, 2011, 9:11 PM <div id="yiv2103237273"><table border="0" cellpadding="0" cellspacing="0"><tbody><tr><td style="font: inherit;" valign="top">Nicola, Thanks so much!
