Thanks for the answer!

However, I did some testings setting the caps to the desired value 
(bpp=32, depth=24 in my case), but my application hangs... I guess I'll 
keep playing around with this.

I've also read that there is a new element called GstAppSrc that makes 
this type of operations (injecting buffers into the pipeline) much 
easier. Do you have any code example with this element?
