[Mlt-devel] Webvfx producer transparency

[j-b-m <j-...@us...>]

Hi,

So if anyone is interested to have a look, here are my changes to make the 
webvfx producers transparent. I think it would be fantastic if we can make it 
work correctly within the MLT framework since it would allow anyone with HTML5 
knowledge to create custom producers to overlay text and graphics over their 
videos.

I still have a problem when trying to use these producers in Kdenlive because 
in EffectsImpl::render(double time, Image* renderImage), the 
QMetaObject::invokeMethod(this, "renderInvokable" (...) sometimes freezes.

You will find my changes on my personal copy of webvfx:

Dan, I am also wondering why you limited the transparency stuff to "plain" 
.html files. It seems to me that the webvfx javascipt enabled version is much 
more useful since we can get the frame position and other infos from MLT to 
use them in the HTML animations. Is there some limitation that made you choose 
this?
