https://github.com/mesonbuild/meson With contributions from: Tim-Philipp Müller <tim@centricular.com> Jussi Pakkanen <jpakkane@gmail.com> (original port) Highlights of the features provided are: * Faster builds on Linux (~40-50% faster) * The ability to build with MSVC on Windows * Generate Visual Studio project files * Generate XCode project files * Much faster builds on Windows (on-par with Linux) * Seriously fast configure and building on embedded ... and many more. For more details see: http://blog.nirbheek.in/2016/05/gstreamer-and-meson-new-hope.html http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html Building with Meson should work on both Linux and Windows, but may need a few more tweaks on other operating systems. |

Videobox -------- This plugin crops or enlarges the image. It takes 4 values as input, a top, bottom, left and right offset. Positive values will crop that much pixels from the respective border of the image, negative values will add that much pixels. When pixels are added, you can specify their color. Some predefined colors are usable with an enum property. The plugin is alpha channel aware and will try to negotiate with a format that supports alpha channels first. When alpha channel is active two other properties, alpha and border_alpha can be used to set the alpha values of the inner picture and the border respectively. an alpha value of 0.0 means total transparency, 1.0 is opaque. The videobox plugin has many uses such as doing a mosaic of pictures, letterboxing video, cutting out pieces of video, picture in picture, etc.. TODO - add enum to specify common aspect ratios/sizes and add borders/crop
