Re: gstreamer-devel Digest, Vol 48, Issue 37

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="http://www.youtube.com/v/6R0NJMGVjf4?f=videos&c=gdataSample-YouTube-1&app=youtube_gdata"  ! 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

Are you using Debian. If so then at times I've had troubles with it installing the full package. Just try a update and reinstall. That's what has worked for me.

  Don't do it like that. Use libgdata to get the flv/mp4 video link.
That url is for the flash player (and not for the actual video file).
  That's how the totem youtube plugin does it and it works like a charm.
Go check how they do it.
