使用 chromium-widevine Debian 软件包

至少从 Debian 9（延伸版本）开始，Debian 包含 contrib 软件包 chromium-widevine。这个包的描述是：

该软件包提供对 Widevine 内容解密模块的支持。

但是，安装此软件包后，我找不到任何 Chromium 识别或正在加载此插件的迹象。 Widevine 在这个包中的位置是/usr/lib/chromium/libwidevinecdmadapter.so。

我目前使用这个包是在 Chromium 上播放 Amazon Prime Video。目前我收到错误：

您的网络浏览器缺少数字版权组件。转到 chrome://components，然后在 WidevineCdm 下单击检查更新。

chrome://components 没有列出 Chromium 下的 WidevineCdm。

对于更奇怪的是，我得到：

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)

那么就libwidevinecdm.so一事无成吗？

知道我应该在这里做什么吗？没有chromium-widevine任何文件或指示应如何进行。

注意：这个问题至少从 Debian 10/buster 开始已经过时了，因为 chromium-widevine 软件包不再存在。

答案1

我在 debian 9.3 上使用 netflix 时运气不佳，chromium-widevine来自 contrib repo。我所做的是：

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

答案2

Debian 声明官方发行版中包含的所有软件包都是免费软件，但 Widevine CDM 库不属于此类别。有一个二进制 blob 可用Chrome 参考构建尽管。

我更新了在 Arch Linux 上找到的一个脚本，用于在 chromium 中下载并安装 Widevine。您只需更新 chromium 安装目录的路径即可。主要区别在于，它还将安装下载的存档中包含的清单，这样可以通过 chrome://components 在 chromium 中显示 Widevine 版本。这里是：

#!/bin/sh

# For ARM use this instead
# https://gist.github.com/ruario/19a28d98d29d34ec9b184c42e5f8bf29

}

# Make sure we have wget or curl
if available wget; then
  SILENT_DL="wget -qO-"
  LOUD_DL="wget"
elif available curl; then
  SILENT_DL="curl -s"
  LOUD_DL="curl -O"

  echo "Install wget or curl" >&2
  exit 1

答案4

由于我没有找到 chromium-widevine Debian 软件包，因此我使用了替代方法“在没有 Google Chrome 的情况下单独安装 Widevine”https://github.com/proprietary/chromium-widevine?tab=readme-ov-file#alternative-install-widevine-alone-without-google-chrome。

您可以使用 GitHub 中的脚本，它将检查最新的 Widevine 版本：https://dl.google.com/widevine-cdm/versions.txt并下载一个（基于您的架构 x64 或 x32），例如https://dl.google.com/widevine-cdm/4.10.2710.0-linux-x64.zip在您的 Chromium 文件夹中创建此目录结构之前（在 Debian 上它以 /usr/lib/chromium/ 开头，但它可能会根据您的 Linux 发行版而变化）：

  /usr/lib/chromium/WidevineCdm
  ├── LICENSE
  ├── manifest.json
  └── _platform_specific
      └── linux_x64
            └── libwidevinecdm.so

该脚本还向文件夹添加权限 755，向文件添加权限 644。
