[gst-devel] Display video in the appointed rect region on QT dialog

[Vincent Zhou]

Thanks Christian.
I can display the video on QT dialog now. 
But I found that sometimes the video captured from webcam is very
obscure and monochrome even I display the video using the following
command.
gst-launch -v v4lsrc ! xvimagesink hue=100 saturation=-100
brightness=100

For the first time when I run the command, the video is very clear 
and colorful. But when run the command again, the video becomes very
obscure and monochrome.  
After that, I use Ekiga to display the webcam video and close Ekiga.
Then I can get good video by that command only for the first time.
I am very confused with it!
Does Anybody have the same experience?
