If you're running Emby Media Server to manage and stream your personal media collection, you probably have heard about hardware transcoding. But what exactly is hardware transcoding and why should you enable it on your Emby setup? In this blog post, we'll break down the benefits of hardware transcoding and explain why it’s a game changer for your media streaming experience. Please keep in mind that hardware transcoding is an Emby Premiere feature and can be purchased HERE.
What is Transcoding?
Transcoding is the process of converting media files from one format to another, optimizing the content to suit the device you're watching on. For example, if you have a high-bitrate 4K movie on your server, but you’re streaming it on a phone or a non 4k TV over a slow internet connection, Emby will transcode the file to a lower resolution or bitrate to ensure smooth playback.
By default, this transcoding happens in software, meaning the CPU does all the heavy lifting. But that’s where hardware transcoding comes into play and can be incredibly helpful.
What is Hardware Transcoding?
Hardware transcoding uses a dedicated component in your computer, such as a GPU or integrated graphics, to handle the transcoding process instead of relying solely on your CPU. This results in faster, more efficient media conversions, and frees up your CPU for other tasks.
Below, we will go into detail as to why hardware transcoding is so important for Emby Media Server.
Top 5 Benefits of Hardware Transcoding in Emby
1. Faster Transcoding and Smoother Playback
Hardware transcoding significantly speeds up the process of converting video files. Since dedicated hardware like GPUs are designed to handle parallel processing, they can manage transcoding tasks much faster than your CPU. This means no more waiting for videos to buffer when streaming to devices that require transcoding.
For users streaming in 4K or on multiple devices at once, the speed boost from hardware transcoding can make a huge difference in ensuring uninterrupted, smooth playback across your media library.
2. Lower CPU Usage, More Efficiency
When you use hardware transcoding, you’re offloading the intense workload of video conversion from your CPU to your GPU or dedicated hardware. This reduces the strain on your CPU, freeing it up to handle other tasks more effectively.
For home servers running on lower-end hardware or even NAS devices, this can be a crucial benefit. With reduced CPU usage, your system can run more efficiently, leading to better performance for other applications and even energy savings in the long run.
3. Better Multi-Stream Performance
If you have multiple family members or friends streaming from your Emby server at the same time, hardware transcoding is a must-have if not every file can be direct played on their client devices. Software transcoding is limited by the power of your CPU, which can quickly become overloaded when handling several streams at once.
With hardware transcoding, your server can manage multiple transcoding tasks simultaneously without lagging or crashing. Whether you’re streaming on a tablet in one room and a TV in another, or your family is accessing your media library remotely, hardware transcoding ensures a seamless experience.
4. Support for High-Resolution Content (4K and HDR)
Streaming 4K HDR content is demanding, and transcoding such high-quality files puts a significant load on your server. Without hardware acceleration, many servers struggle to downscale 4K videos, leading to stutters, buffering, or even failed streams.
Hardware transcoding, especially with modern GPUs and iGPUs, is optimized for high-resolution content. It can handle 4K, HEVC, and other high-bitrate formats much more efficiently than software transcoding, providing smoother playback for high-res media.
5. Energy Efficiency and Longevity
Since hardware transcoding is faster and more efficient than software transcoding, it uses less power overall. When your server doesn’t have to push its CPU to the limit, it consumes less electricity, which can be a big plus for those concerned about their energy bills.
Additionally, since the hardware is doing the heavy lifting, your CPU experiences less wear and tear over time. This can prolong the life of your system, especially if you're running your Emby server 24/7.
How to Enable Hardware Transcoding in Emby
Enabling hardware transcoding in Emby is straightforward, but it requires compatible hardware. Many Intel CPUs with integrated graphics, as well as dedicated NVIDIA or AMD GPUs, support hardware transcoding.
- Check Your Hardware: Ensure your CPU or GPU supports hardware transcoding. Intel Quick Sync, NVIDIA NVENC, and AMD VCE are popular options.
- Install Necessary Drivers: Make sure the correct drivers for your GPU are installed and up to date.
-
Enable Hardware Acceleration in Emby:
- Go to Server Dashboard in Emby.
- Navigate to Transcoding settings.
- Check the option to Enable hardware acceleration when available.
- Select your preferred hardware transcoding engine (e.g., Quick Sync, NVENC) under the advanced tab if preferable. - Test Your Setup: Start streaming from a device that requires transcoding or force transcoding and monitor your server's CPU and GPU usage to confirm that hardware transcoding is active.
If you’re serious about getting the most out of your Emby Media Server, hardware transcoding is a must. By leveraging the power of your GPU or integrated graphics, you can enjoy faster transcoding times, smoother playback, better multi-stream performance, and energy savings. Whether you’re streaming 4K movies or sharing your media library with family, hardware transcoding ensures that your server runs efficiently and delivers the best possible viewing experience.
