gst-launch elements usage

[sharief]

Hello
I dont know how to use this gst-inspect elements. When i do
"gst-inspect mfw_v4lsink" i get


[code]
fullscreen : If true it will be Full screen
flags: readable, writable
Boolean. Default: false Current: false
[/code]

But i dont know how to implement this fullscreen option. Please help me. i used as mfw_v4lsink fullscreen=true. still Its not working.playing in small window only.

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

[fabio_estevam]

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.

yes i am using VGA for displaying. Its works fine after using disp-height and disp-width parameters. but now my another problem is the video is not played for second time its saying that "Allocation of frame buffers failed". i have to relogin to play the video second time. please help me

[fabio_estevam]

What is your kernel command line?

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