MapEngine Media Extension

MapEngine Media Extension

Description

MapEngine Media Extension is an extension library for MapEngine.
It provides an additional API for playing video and streaming live content using MapEngine.

The Extension uses bytedeco/javacv's FFmpeg implementation for decode media.
JavaCV, JavaCPP and FFmpeg will be downloaded on server startup and loaded into the classpath.
This plugin downloads only the currently needed libraries for the current operating system and architecture.

Features

• Runtime dependency downloader
• FFmpeg based media decoding

Usage

MapMediaExt has to be added as a dependency to the plugin.yml regardless of the build system used.

Example

public class Bar {

    public void foo(IMapDisplay display, URI streamUri) {
        // create a drawing space for the display
        IDrawingSpace space = plugin.mapEngine().pipeline().drawingSpace(display);
        
        // add all online players as receivers
        space.ctx().receivers().addAll(Bukkit.getOnlinePlayers());

        // create a new frame source with a 10 frame buffer and rescaling enabled
        FFmpegFrameSource source = new FFmpegFrameSource(streamUri, 10, space, true);
        
        // start the decoding process
        source.start(); 
    }
}
