为什么minidlna要关闭与客户的连接？

Question

操作系统: NixOS不稳定应用程序：迷你型

我在Debian和我的电视上成功地使用了minidlna。但我在NixOS上遇到了问题。

这是我的NixOS配置(/etc/nixos/configuration.nix)：

#DLNA
services.minidlna.enable = true;
services.minidlna.settings = {
  friendly_name = "PCMEDIA";
  media_dir = ["V,/mnt/ORION/DLNA/"];
  log_level = "debug";
};

这是当我试图用我的电视连接到DLNA服务器时的日志：

$ sudo journalctl --unit minidlna -r

如何使微型机器人工作？不只是我的电视，它不工作与VLC或任何其他DLNA能力的应用程序。

Answer 1

minidlna无法访问指定的“媒体目录”。NixOS以用户minidlna的身份运行minidlna。因此，需要将用户minidlna添加到访问媒体目录中指定位置的用户组中。

/etc/nixos/configuration.nix:

services.minidlna.enable = true;
services.minidlna.settings = {
  friendly_name = "Movies";
  media_dir = ["V,/mnt/ORION/DLNA/"];

  # so changes in media dirs are updates in the server listing
  # also make sure "inotify-tools" packages is installed
  inotify = "yes"; 
  #log_level = "debug";
};

users.users.minidlna = {
  extraGroups = [ "users" ];
};

另外，如果您试图以系统用户的身份运行minidlna，您可能希望清除/var/cache/minidlna或db_dir。

Answer 2

使用类似于/mnt/ORION/DLNA/的内容检查ls -ld /mnt/ORION/DLNA的名称和权限。

而且，而不是

media_dir = ["V,/mnt/ORION/DLNA/"];

试一试

media_dir = V,/mnt/ORION/DLNA

(按照大写，没有括号，没有引号，也没有尾随斜杠)，否则您可能会没有有效的路径，这可能是早期关闭的原因之一。
