Managing Emby Resources on the Raspberry Pi

When running Emby server on the Raspberry Pi, there are a few things you can do to optimize performance:

  1. Use an External USB Drive for Storage

Ideally, store your media library on an external USB hard drive or flash drive rather than the SD card. This will avoid wearing out the SD card prematurely.

  1. Adjust Transcoding Settings

Emby automatically converts or transcodes media files if needed for a particular device. However, transcoding can be CPU and RAM intensive.

To avoid overloading your Pi:

  • Disable video throttling in Settings > Playback
  • Set a conservative maximum simultaneous transcodes in Settings > Server > Transcoding > Maximum concurrent transcodes
  1. Enable Hardware Accelerated Video Encoding

If you have a Raspberry Pi 4, you can offload H.264 video transcoding to the GPU:

echo “dtoverlay=vc4-fkms-v3d” | sudo tee -a /boot/config.txt

sudo reboot

This will speed up streaming to many devices.

  1. Clean Cache and Logs

Emby caches artwork, guide data and other temporary files over time. To clear space you can:

emby-server clean  # clears program data cache

emby-server restart  # restarts the server

  1. Lower Log Verbosity

Adjust logging levels in Settings > Logging if the logsgrow too large.

With a few optimizations like these, your Emby server will run smoothly on the Raspberry Pi without lag or crashing.

Troubleshooting Emby Server Issues

Some common problems and fixes:

  • Can’t login to web interface: Reset admin password via command line

emby-server changepassword your_username new_password

  • Media won’t stream: Ensure filenames don’t have special chars, restart service

sudo service emby-server restart

  • Missing metadata: Run library scan to refresh info
  • Buffering or crashes: Increase Minimum SMB protocol version to 2.0 or 3.0 in Settings

See the Emby documentation for more troubleshooting tips.
