Usando il pacchetto Debian chromium-widevine

Almeno da Debian 9 (stretch), Debian contiene il pacchetto contrib chromium-widevine. La descrizione di questo pacchetto è:

Questo pacchetto fornisce supporto per il modulo di decodifica del contenuto widevine.

Tuttavia, dopo aver installato questo pacchetto, non riesco a trovare alcun segno che Chromium riconosce o sta caricando questo plugin. La posizione di Widevine in questo pacchetto è /usr/lib/chromium/libwidevinecdmadapter.so.

Il mio attuale utilizzo per questo pacchetto è riprodurre Amazon Prime Video su Chromium. Attualmente sto ricevendo l'errore:

Nel tuo browser web manca un componente per i diritti digitali. Vai a chrome: // Components e in WidevineCdm, fai clic su Controlla aggiornamenti.

chrome: // componenti non elenca WidevineCdm in Chromium.

Per extra strano, sto ottenendo:

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)

Quindi non si libwidevinecdm.sorisolve in niente?

Hai idea di cosa dovrei fare qui? Non chromium-widevineha documentazione o indicazioni su come procedere.

NOTA: questa domanda non è aggiornata, almeno a partire da Debian 10 / buster, perché il pacchetto cromo-widevine non esiste più.

Non ho avuto fortuna usando netflix con chromium-widevinedebian 9.3 dal contrib repo. Quello che ho fatto è stato:

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 afferma che tutti i pacchetti inclusi nella distribuzione ufficiale sono software gratuiti, ma le librerie CDM Widevine non rientrano in questa categoria. Tuttavia, nella build di riferimento di Chrome è disponibile un BLOB binario .

Ho aggiornato uno script trovato su Arch Linux per scaricare e installare widevine in chromium. Devi solo aggiornare il percorso alla directory di installazione di chromium. La differenza principale è che installerà anche il manifest incluso nell'archivio scaricato e in questo modo può mostrare la versione widevine tramite chrome: // componenti in cromo. Ecco qui:

#!/bin/sh

# For ARM use this instead
