Does Gstreamer has a element that can split one stream into two

[Chen, Weian]

Hi all:

 

If I have a RGB format stream (decoded from H.264 through H.264 decoder element as an example) and I want display (link to xvimagesink) and save on disk (filesink) at one time, does Gstreamer has such filter element which is used to link above H.264 decoder element and xvimagesink/ filesink?

 

Thanks in advanced.

 

Weian

The 'tee' element might do what you want. Don't forget to add a queue
after tee for each stream, e.g.:

  gst-launch-0.10 videotestsrc ! tee name=t  \
    t. ! queue ! ximagesink  \
    t. ! queue ! ximagesink

Cheers

Could you explain why?
