Hello ! I have cross compiled gstreamer and required plugins for MIPS and tried to  play an ogg file. I get the following error # gst-launch-0.10 -v playbin uri=file:///usr/local/lib/eatv-public.ogg Setting pipeline to PAUSED ... /playbin0/decodebin0/typefind.src: caps = application/ogg Pipeline is PREROLLING ... ** Message: don't know how to handle audio/x-vorbis /playbin0/selector_video_src0: active-pad = NULL (gst-launch-0.10:1537): GStreamer-CRITICAL **: gst_event_new_new_segment_full: assertion `start != -1' failed /playbin0/decodebin0/queue0.sink: caps = video/x-theora /playbin0/decodebin0/queue0.src: caps = video/x-theora (gst-launch-0.10:1537): GStreamer-CRITICAL **: gst_event_new_new_segment_full: assertion `start != -1' failed ERROR: from element /playbin0/decodebin0/oggdemux0: Internal data stream error.

My Configuration is below, which I think means I have vorbis, theora and ogg plugins requierd to play an Ogg file are going to be present. I have also cheked that these are present on target. configure: *** Plug-ins without external dependencies that will NOT be built: configure: *** Plug-ins with dependencies that will be built:         alsa         cdparanoia         ogg         theora         video4linux         vorbis configure: *** Plug-ins with dependencies that will NOT be built:         gio         gnomevfs         libvisual         pango         ximagesink         xvimagesink Can I get some Idea on what might be going wrong? However on my ubuntu x86 desktop, the same media file is being played. regards -Nitin
