Hi,
How about looking in the documentation first? ;-)
Here is an example which could be found at the beginning of the
documentation for videoscale element:
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-videoscale.html--------
gst-launch -v filesrc location=videotestsrc.ogg ! oggdemux ! theoradec
! videoscale ! video/x-raw-yuv, width=50 ! xvimagesink
Decode an Ogg/Theora and display the video using xvimagesink with a
width of 50.
--------
You need a caps filter after videoscale element to specify the desired
width and height as shown in the example above.
Andrey.

Beautiful is writing same markup. Internet Explorer 9 supports
standards for HTML5, CSS3, SVG 1.1, ECMAScript5, and DOM L2 & L3.
Spend less time writing and rewriting code and more time creating great
