Hello everybody,  im trying to create a pipeline to decode bmp files and display on the xvimagesink. here's the pipeline i've constructed pipeline 1 using ffdec_bmp: gst-launch filesrc location=file.bmp ! ffdec_bmp ! ffmpegcolorspace ! queue ! xvimagesink [Dump] Setting pipeline to PAUSED ... Pipeline is PREROLLING ... ERROR: from element /pipeline0/ffdec_bmp0: Internal GStreamer error: negotiation problem.  Please file a bug at <a href="http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer">http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer </a>.
