Hi, I have been trying to play Youtube videos using gstreamer but have not been successful in doing so.From what i could figure out, swfdec plug-in is required to play youtube vides because youtube supports flash video. As per gstreamer plug-in overview page, this plug-in should be available in "bad plugins". This plug-in has some external dependecy on libswfdec. Even after installing this library, this plug-in does not show in the list of the elements. The configure script in "bad plug-ins" searches for 0.3 version of swfdec, which is already obsolete. I have tried bypassing this , but "swfdec" plug-in is still not built. I have tried the following pipelines. gst-launch-0.10 souphttpsrc location="<a href="http://www.youtube.com/v/6R0NJMGVjf4?f=videos&c=gdataSample-YouTube-1&app=youtube_gdata">http://www.youtube.com/v/6R0NJMGVjf4?f=videos&c=gdataSample-YouTube-1&app=youtube_gdata</a>" ! decodebin ! ximagesink Setting pipeline to PAUSED ... Pipeline is PREROLLING ... ERROR: from element /GstPipeline:pipeline0/GstDecodeBin:decodebin0/ffdemux_swf:ffdemux_swf0: GStreamer encountered a general supporting library error. Additional debug info: gstffmpegdemux.c(1243): gst_ffmpegdemux_open (): /GstPipeline:pipeline0/GstDecodeBin:decodebin0/ffdemux_swf:ffdemux_swf0: Input/output error ERROR: pipeline doesn't want to preroll. Setting pipeline to NULL ... Freeing pipeline ... Any help would be greatly appreciated. Thanks, Shaw
