You have to use two more plugins appsrc &appsink So your application will look like fread -> {appsrc ! decoder ! appsink } ->fwrite Best Luck Kapil <div class="gmail_quote">On Tue, Sep 27, 2011 at 7:28 PM, Siber <<a href="mailto:marchenkovadim@mail.ru">marchenkovadim@mail.ru</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hello everybody! Can I use only one plugin in a pipeline for my application? I want to make a very simple application: I read some data from a file (e.g with function fread(....)), then pass the buffer filled with a data from the file to a decoder and at last I save decoded data to another file (e.g. with function fwrite(...)). I know that there are special plugins: filesrc and filesink, but still can I escape necessity of using this plugins and read and save data "manually"? -- View this message in context: <a href="http://gstreamer-devel.966125.n4.nabble.com/Using-only-one-plugin-in-a-pipeline-tp3847453p3847453.html" target="_blank">http://gstreamer-devel.966125.n4.nabble.com/Using-only-one-plugin-in-a-pipeline-tp3847453p3847453.html</a> Sent from the GStreamer-devel mailing list archive at Nabble.com. _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div> -- <a href="http://www.linkedin.com/in/kapilagrawal" target="_blank">http://www.linkedin.com/in/kapilagrawal</a> <a href="http://www.mediamagictechnologies.com" target="_blank">www.mediamagictechnologies.com</a> (Consultancy - Multimedia, Gstreamer, ffmpeg, Streaming for platforms- linux, windows, TI, android)
