Based on ccrisan's version 20170710, but with hwaccel for Raspberry Pi. More information about hwaccel here motioneye-project#365.
This is completely untested and highly experimental. Use at your own risk.

To get the optimum configuration, tune the following:

  • Resolution : higher resolution uses more memory and CPU
  • Framerate : higher frame rate uses more CPU
  • Pre-capture : pre-captured frames are stored in RAM
  • Minimum motion frames : frames are stored in RAM as well
  • bcm2835-v4l2 max_video_width and max_video_height : higher number uses more GPU memory, if set lower than configured resolution, camera uses still mode i.e. low fps, no AE/AGC.
    • Remount root filesystem as read-write.
    • Edit /etc/modules file.
  • GPU memory : allocating less GPU memory means more memory for MotionEye. Examples below for bcm2835-v4l2 max_video_width=1920 max_video_height=1200
    • 800 x 600 resolution : 66MB
    • 1280 x 720 resolution : 70MB
    • 1280 x 1024 resolution : 75MB
    • 1920 x 1080 resolution : 83MB
    • Use "gpu_stats" script to check GPU available memory.
  • Disable FTP server and/or Samba server if not needed.

Pi Zero W example configuration:

  • GPU memory: 70M
  • Resolution: 1280 x 720
  • Frame rate: 20 fps
  • Movie format: H.264 (mp4 or mkv)
  • Pre-capture: 20 frames or less (higher pre-cap uses more RAM)
  • Minimum motion frames: 15 frames (higher value uses more RAM)
  • Disable FTP server and/or Samba server if not needed.
  • No live-stream and no web browser connection as it loads the CPU.

It is possible to run 1024 x 576 resolution on Raspberry Pi 256MB RAM, but need to tweak a few things to optimize the memory usage:

  • /etc/modules: bcm2835-v4l2 max_video_width=1024 max_video_height=600
  • GPU memory: 66MB
  • Pre-capture: 0 frame
  • Frame rate: 15 fps
  • Minimum motion frames: 10 frames or less
  • Disable FTP server and Samba server (under web UI services section)
  • No live-stream and no web browser connection as it loads the CPU.

Known issues / limitations:

  • Wifi stops working after first boot when connecting to certain access points. Workaround here: motioneye-project#1012
  • Samba server may not work with Windows 10.
