I am not sure about a producer at this time; it will require some study. One idea for now is that you implement a Movit effect and then make a MLT filter for it with an opacity parameter. Also, I think some of those GLSL examples have an implied background that could instead be MLT video. Another approach is to use WebVfx with QtWebKit that includes WebGL, and there is already a producer for that. A recent enough version supports WebGL: http://blogs.kde.org/2012/11/14/introducing-qtwebkit-23 At least, according to a package search, Qt 4.8 on Ubuntu 13.04 includes this version. If you follow some of my and the mailing list's activity lately, you will see renewed interest in WebVfx. I helped a friend's business use it this winter, and they might try to port it to Qt5. Recently, I started including it in Shotcut builds (does not support WebGL everywhere at this time), and JB has been experimenting with it in Kdenlive refactoring. Imagine an integration, where, in edit mode, you can use mrdoob's embedded editor. :-) -- +-DRD-+ ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Mlt-devel mailing list Mlt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mlt-devel
