Haxe / Openfl/ Is it possible to load a video (.mp4) from the Assets file and display it in the stage?

Question

Why does Haxe have such poor documentation" Why are there no examples at all?

Answer 1

You can simply check libraries to see if there is something available like

https://lib.haxe.org/p/hxCodec

Answer 2

It depends of the platform you're targeting to.

OpenFL can play videos on HTML5, however, it cannot play them natively (Windows, macOS, Linux).
For native platforms, consider searching for a library.

If you're targeting a native platform, as Ilir Liburn said, use hxCodec.
If not, check out the PlayingVideo example OpenFL provides.
