Usando el paquete Debian chromium-widevine

Al menos a partir de Debian 9 (estiramiento), Debian contiene el paquete contrib chromium-widevine. La descripción de este paquete es:

Este paquete proporciona soporte para el módulo de descifrado de contenido widevine.

Sin embargo, después de instalar este paquete, no puedo encontrar ninguna señal de que Chromium reconozca o esté cargando este complemento. La ubicación de Widevine en este paquete es /usr/lib/chromium/libwidevinecdmadapter.so.

Mi uso actual para este paquete es reproducir Amazon Prime Video en Chromium. Actualmente recibo el error:

A su navegador web le falta un componente de derechos digitales. Vaya a chrome: // components y en WidevineCdm, haga clic en Buscar actualización.

chrome: // components no incluye WidevineCdm en Chromium.

Por extra raro, estoy obteniendo:

root@orwell:/usr/lib/chromium# ldd libwidevinecdmadapter.so 
        linux-vdso.so.1 (0x00007ffccbfad000)
        libwidevinecdm.so => not found
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f08c6e5b000)
        libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f08c6ad3000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f08c6733000)
        /lib64/ld-linux-x86-64.so.2 (0x000055e84bdbe000)
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f08c642b000)
        libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f08c6213000)

Entonces se libwidevinecdm.soresuelve a nada?

¿Alguna idea de lo que se supone que debo hacer aquí? El chromium-widevineno tiene documentación o indicación de cómo se supone que se debe proceder.

NOTA: Esta pregunta está desactualizada, al menos a partir de Debian 10 / buster, porque el paquete chromium-widevine ya no existe.

No tuve suerte usando netflix con chromium-widevinedebian 9.3 de contrib repo. Lo que hice fue:

wget https://dl.google.com/widevine-cdm/1.4.8.1008-linux-x64.zip
unzip 1.4.8.1008-linux-x64.zip
sudo mkdir /usr/lib/chromium
sudo mv libwidevinecdm.so /usr/lib/chromium
sudo chmod 644 /usr/lib/chromium/libwidevinecdm.so

Debian afirma que todos los paquetes incluidos en la distribución oficial son software libre, pero las bibliotecas Widevine CDM no están en esta categoría. Sin embargo, hay un blob binario disponible en la compilación de referencia de Chrome .

He actualizado un script que se encuentra en Arch Linux para descargar e instalar widevine en cromo. Solo necesita actualizar la ruta al directorio de instalación de chromium. La principal diferencia es que también instalará el manifiesto incluido en el archivo descargado y de esta manera puede mostrar la versión widevine a través de los componentes chrome: // en cromo. Aquí está:
