Cheers, Ronald ---------- Forwarded message ---------- From: mehrdad fallahpour <<a href="mailto:mehrdadfallahpour@gmail.com" target="_blank">mehrdadfallahpour@gmail.com</a>> Date: Tue, Dec 22, 2009 at 7:49 AM Subject: Question about using GStreamer To: <a href="mailto:rbultje@ronald.bitfreak.net" target="_blank">rbultje@ronald.bitfreak.net</a> Dear Ronald I'm Mehrdad an Electronic Engineer. I want to produce an embedded video processor using lovely Linux & GStreamer. I have been working on application with Gtk+ and Gstreamer to show and process video. I want to show the original Video in a Ximage and after processing data show processed data on another seperate Ximage of Gtk. I could show Video frames with playbin and uri of GStreamer but unfortunately when I want to make it with a pipeline and linking low-level elements like source (filesrc), demux, queue, decoder, ffmpegcolorspace and vscale and videosink, they can't link correctly and it's bus issues a message of "Internal data stream error". This is very big problem with very few source and example for GStreamer in the Internet and it causes I involved to this trouble 3 weeks. Dear Wim if possible do a favor for me and guide me in this issue (at least an useful link in the Internet). I'm looking forward to hearing from you.
