This is a guide for installing widevine on Arch Linux ARM to watch netflix on Chromium.

Prepare the Environment¶

• Make sure the system is up to date:
  

  sudo pacman -Syu
  

• Install multipath-tools:
  

  sudo yaourt multipath-tools
  

Install Widevine¶

• Download and unzip the following chromeos recovery image:
  

  wget https://dl.google.com/dl/edgedl/chromeos/recovery/chromeos_7077.134.0_daisy-skate_recovery_stable-channel_skate-mp.bin.zip
  unzip chromeos*.zip
  

• Access to the files stored on that ChromeOS image:
  

  sudo kpartx -avs chromeos*.bin
  

  • Example output
    

    add map loop0p1 (254:1): 0 28672 linear 7:0 2928640
    add map loop0p2 (254:2): 0 32768 linear 7:0 20480
    add map loop0p3 (254:3): 0 2641920 linear 7:0 286720
    add map loop0p4 (254:4): 0 32768 linear 7:0 53248
    add map loop0p5 (254:5): 0 4096 linear 7:0 282624
    add map loop0p6 (254:6): 0 1 linear 7:0 16448
    add map loop0p7 (254:7): 0 1 linear 7:0 16449
    add map loop0p8 (254:8): 0 32768 linear 7:0 86016
    add map loop0p9 (254:9): 0 1 linear 7:0 16450
    add map loop0p10 (254:10): 0 1 linear 7:0 16451
    add map loop0p11 (254:11): 0 16384 linear 7:0 64
    add map loop0p12 (254:12): 0 32768 linear 7:0 249856
    

• We're interested in the one ending in p3, which will now exist at /dev/mapper/loop0p3. Now mount it:
  

  sudo mkdir -p /tmp/chromeos
  sudo mount -t ext2 /dev/mapper/loop0p3 -o ro /tmp/chromeos/
  

• Now move into the root of that partition and search for the widevine plugins:
  

  cd /tmp/chromeos/
  find . -type f -name "libwidevine*" 
  

  • Example output
    

    ./opt/google/chrome/libwidevinecdm.so
    ./opt/google/chrome/libwidevinecdmadapter.so
    

The two files you want are named libwidevinecdm.so and libwidevinecdmadapter.so (ignore any "Permission denied" errors).

sudo cp ./opt/google/chrome/libwidevine*.so /usr/lib/chromium/

Tricking Netflix¶

• Once Chromium is loaded up, install the "User Agent Switcher" extension from the Play Store, then add the following user agent as "Chrome":
  

  Mozilla/5.0 (X11; CrOS armv7l 6946.63.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36
  

• In the "User Agent Switcher" tool, set that as a permanent override for netflix.com.
