Use git clone --recurse-submodules -b 1.1.0 ... to make building with qmelt easier.

  • Added support for alpha channels in MLT video for input and output.
  • Added a transparent property to the MLT filter. When the property is set to 1, this gives a filter a transparent white canvas for drawing while the MLT video image is still available through the JavaScript extension. This facilitates using WebVfx to draw the alpha channel independently of the MLT alpha channel.
  • Added support for getting a MLT rectangle property (mlt_rect) as a JavaScript object with properties: x, y, width, height, and opacity.
