Hardware-Accelerated Streaming with Plex, Jellyfin & Emby on ZimaOS, The Definitive Guide
Giorgio Zhang - Aug 29, 2025
Your 4K movie stutters. Your server’s CPU hits 100%. The fan screams. You’ve hit the transcoding wall. On the road, it’s even worse: that massive 20GB file is impossible to stream over slow hotel Wi-Fi or your expensive mobile data plan. You’ve hit the transcoding wall. But what if you could build a media server that handles multiple 4K streams effortlessly, without breaking a sweat?
Welcome to the world of Hardware-Accelerated Streaming. With ZimaOS, this isn’t a complex command-line nightmare. It’s a reality you can build in minutes. This is how you leverage your GPU to create a media powerhouse. Today, we will use an nvidia GPU as an example.
Hardware-Accelerated Streaming: What and Why
A media server, powered by apps like Plex, Jellyfin, or Emby, organizes your personal movie, TV show, and music collections, letting you stream them to any device.
But here’s the catch: your 4K video file isn’t always compatible with your phone or browser. The server must “transcode” (convert) it in real-time. This is incredibly CPU-intensive.
Hardware Transcoding offloads this job to your system’s GPU (Graphics Processing Unit). The result?
- Flawless 4K Playback: No more buffering.
- Smooth Remote Streaming: Watch on the go without killing your data plan.
- Multiple Streams: Your family can watch different things at once.
- Low CPU Usage: Your NAS stays responsive for other tasks, like file transfers or backups.
Real World Setup by Community Users
We see users building incredible setups. Of course, you can make it in a single machine. Here, a popular and highly efficient approach is shared: the dual-device strategy, separating tasks for maximum performance while maintaining flexibility. Here’s a look at Bill’s personal setup:
Pro-Tip: Many of our users also start with CasaOS as a lightweight app server and use a more powerful ZimaOS machine purely for storage and backup. The flexibility is yours. See comparison between CasaOS and ZimaOS.
Setting it up is shockingly simple:
- 1. One-Click Install: On ZimaOS App Server (
10.0.0.68), Bill opened the ZimaOS App Store. Then he searched for “Jellyfin” and clicked Install. That’s it. ZimaOS handles the complex Docker configurations behind the scenes. No YAML files, no manualdocker runcommands. - 2. Connect the Storage: In the Jellyfin web interface, Bill added his media library. Simply pointed it to his Storage Server’s SAMBA share (e.g.,
/media/10.0.0.84/movies). About how to understand Docker App path on ZimaOS, please refer to this documentation. - 3. Enable Hardware Acceleration: This is the final, crucial step. Inside Jellyfin’s dashboard:
- – Navigate to
dashboard > playback > transcoding - – Select NVIDIA NVENC as the hardware acceleration option.
- – Check all the boxes for formats you want to accelerate (H.264, HEVC, etc.).
- – Hit Save.
You are done. Your ZimaOS media server is now using the GPU for all heavy lifting. The great news is that the process for Plex and Emby is virtually identical. You can find them in the ZimaOS App Store for the same one-click installation. Once installed, you’ll find the hardware acceleration toggle within their respective
Transcoding menus.
Feature availability can differ between these applications. For Plex and Emby, hardware-accelerated transcoding is generally a premium feature unlocked via subscription services (Plex Pass and Emby Premiere) while Jellyfin includes this functionality by default. ZimaOS provides a robust platform for whichever ecosystem you choose.
Conclusion
Building a high-performance media server used to be a badge of honor for tinkerers who spent weekends in the command line.
With ZimaOS, that’s history. We believe powerful technology should be accessible. You just saw how a one-click app installation and a few simple clicks can create a streaming setup that rivals expensive, off-the-shelf solutions. You didn’t just install an app; you deployed a fully hardware-accelerated media powerhouse.
