[gst-devel] gst-opencv app compile error with OpenCV 2.2

[Robert Jobbagy]

Hi Guys,

I used my gst-opencv filter with OpenCV 2.0 and worked fine.
I tried update to OpenCV 2.1 because I found a bug.
But OpenCV 2.1 has the bug too and tried update to OpenCV 2.2.

And I gave this compile error:

the bug why I updated:

 I would like to use alpha blending.
I followed Shervin Emam instructions but it isnt help :(
The alpha blending method:

I split the input frame into 3 image from the 3 channel.
and I use cvAddWeighted function on 3 image and add 3 other image with
alpha and beta equal 0.5.
and after I merge this images

after this method the video is flicking and I see some sub image in
the frame etc ...

So I think this is a bug. And doesnt solved the update to newer OpenCV version.

Any idea ?
