Raspbian is a Debian-based operating system for the Raspberry Pi.

It utilizes the following features:

• Stream videos in HD with hardware-accelerated MPEG-4 decoding.
• Play 3d video games with hardware-accelerated graphics rendering:
  • Raspberry Pi 3
    • The proprietary OpenGLES driver (better performance)
      is installed by rpi-update, which installs libEGL.so and libGLESv2.so.
    • The (experimental) open source OpenGL driver VC4
      can be enabled using raspi-config.
  • Raspberry Pi 4
    • The open source OpenGL driver V3D is enabled by default.

After Raspbian has been installed, I recommend having a look at
post_install_rasp.sh, which is found at the bottom of this page.
