[gst-devel] Using videoscale with custom video sink

[Andrey Nechypurenko]

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.
