我安装了 Linux 和 Windows 双启动，现在我无法播放来自其他已安装分区的任何视频。
我还应该提到，只有视频有这个问题，我可以毫无问题地打开图片、文档、音乐……。另外，问题不在于视频编解码器，如果我将视频复制并粘贴到 Linux 分区中，它可以完美播放。
我尝试使用 smPlayer 和媒体播放器打开，但没有成功。SmPlayer 错误日志：

我尝试使用 sudo 安装分区，但问题并没有得到解决。
我从某处读到，问题可能是因为分区格式不是 ext4，但在此之前我有 linux manjaro，并且从同一个分区播放视频没有问题。
答案1
SMPlayer snap 似乎没有权限访问该分区。这似乎是 snap 的问题。安装 APT 版本应该可以解决这个问题。
sudo snap remove smplayer
sudo apt install smplayer
答案2
这很可能是由于折断关于连接的应用程序可移动媒体接口通常不是默认授予...您可以smplayer像这样检查是否已安装 snap：
$ snap connections smplayer
