I’m trying to build a Java application that can stream video directly to Twitch but I’m having trouble finding good examples online. Most tutorials I’ve found don’t actually work or are outdated.
I want to know if it’s possible to create my own RTMP implementation in Java for this purpose, or if there are better approaches. Has anyone successfully built a Java-based streaming solution for Twitch?
I’ve been searching for working code samples but haven’t found anything reliable yet. Any guidance on the best libraries or methods to use would be really helpful.
What’s the recommended way to handle the video encoding and streaming protocol when working with Twitch’s API from a Java application?
Don’t build RTMP from scratch - it’s way overkill. I wasted weeks trying before I switched to FFmpeg with ProcessBuilder. Here’s what actually works: use Java for your app logic and UI, then let FFmpeg handle the streaming as an external process. Pure Java video encoding is a nightmare - you’ll hit performance walls and compatibility issues constantly. Instead, prep your video content in Java, pipe it to FFmpeg, and let it do the H.264 encoding plus RTMP streaming to Twitch. You can still control FFmpeg parameters and monitor everything programmatically. Just grab your Twitch stream key, use the right ingest endpoint, and you’re set. FFmpeg’s RTMP support is rock solid and handles all the protocol mess that’d take you months to code properly. This combo gives you Java’s flexibility where you need it while using proven streaming tech for the heavy lifting.
