树莓派运动权限问题

Question

我在树莓派上安装了运动，一旦我在相机前进行“运动/移动”，它就会崩溃。

错误如下：

Nov  9 14:49:55 raspberrypi motion: [1] [ERR] [ENC] ffmpeg_open: url_fopen - error opening file /var/lib/motion/01-20161109144955.avi ... check access rights to target directory:

我知道这与权限有关，但我已经在

/tmp

中创建了运动目录并设置了

chown motion:motion motion

，根据我的理解，这不应给出此类错误。

Answer 1

正如您从粘贴的日志摘录中看到的，文件写入发生在

/var/lib/motion/

目录中。因此，如果您更正该目录的权限，它应该可以工作。或者更改应用程序的设置以写入 /tmp/motion 目录。

请参阅

target_dir
