When you do a gst-inspect mfw_v4lsink you will also see the width and height properties. You also need to set them to the correct dimensions that you want to play.

There is a '=' missing in your pipeline. It should be fullscree
n-width=400

yes i am sorry. But when i give all the options correctly it is playing in different location in scrren according to the value. But it is in same size. The fullscreen is not working. "fullscreen-width and fullscreen-height" is changing the location in the monitor. not the size of the video. Please help me

Where are you displaying (LCD monitor via DVI port, WVGA display, VGA, etc)?

You pass in the kernel command line the video resolution that you are using.

What is your kernel command line?

What is the command line you use to launch the video?
