|(require video/player)||package: video|
VidLang comes with a player to quickly preview videos before the final render. You can access it from DrRacket with the Preview Video button. It appears next to the run button when a VidLang file is open. Alternatively, you can use raco video -p <file.vid> from the command line.
Several of the features of the video preview are disabled. This is because they are unstable and not yet ready for release. They should be available in the next version of Video, or in the latest unstable build.
data is the producer that the video player will render.
