Using videomixer and alpha channel

[Eric Trousset]

Hi,

I am using, videomixer to mixer to streams, but it seems the alpha channel is not used for the mixing, eg, part of the image with a 0 alpha aren't transparent...

Is there a way to enable alpha transparency in the video mixer?

Also, I am using imagefreeze to display a still image. Is there a way to make this element to ask the source for a new image at some point?

Cheers,
Eric TROUSSET.
