## Render text on top of a video
Through adding a Source and a Sink v2d becomes capable of video editing. Reads a video, renders text on top and writes the result. Note: Reading and writing of video-data is multi-threaded in the background for performance reasons.

@include samples/cpp/video_editing.cpp
