Faruk: One thing I forgot on the pipeline example in my response was the '--*eos* -on-*shutdown' option *after 'gst-launch'. This is needed by the 'filesink' element in order to properly close the file on a SIGINT. gst-launch -v --eos-on-shutdown gnomevfssrc location=http://admin:mncamera@192.168.1.176/img/video.asf ! tee name=t ! queue ! fluasfdemux ! mpeg4videoparse ! flumpeg4vdec ! xvimagesink t. ! queue ! fluasfdemux ! mpeg4videoparse ! mp4mux ! filesink location=file.mp4 Best Regards, -- Rob Krakora Senior Software Engineer MessageNet Systems 101 East Carmel Dr. Suite 105 Carmel, IN 46032 (317)566-1677 Ext. 206 (317)663-0808 Fax On Tue, Sep 21, 2010 at 4:52 PM, Robert Krakora < rob...@me...> wrote: > Hi Faruk, > > I believe that you want something like this: > > gst-launch -v gnomevfssrc location=http://admin:mncamera@192.168.1.176/img/video.asf ! tee name=t ! queue > > ! fluasfdemux ! mpeg4videoparse ! flumpeg4vdec ! xvimagesink t. ! queue ! > fluasfdemux ! mpeg4videoparse ! mp4mux ! filesink location=file.mp4 > > This pipeline plays back an MPEG4 video in an ASF container from a Linksys WVC200 PTZ camera over an HTTP connection and also transcodes and stores > > it as an 'mp4' file.
