使用Flatpack的Linux服务器上的HandBrake命令行不起作用- hb_stream_open PATH_TO_FILE失败

Question

通过flatpack运行HandBrakeCLI -无法打开任何文件。

flatpak run --filesystem=host --command=HandBrakeCLI fr.handbrake.ghb -i "/var/www/html/mit4mit.co.il/httpdocs/vimeo/drop.avi" -o "/var/www/html/mit4mit.co.il/vimeo/converted.mp4"

无论我做什么，我都不能让HandBrakeCLI找到输入文件。我在网上看到，这里最重要的一行是hb_stream_open -上面的所有故障都是正常的。

这是因为flatpack正在沙箱它的应用程序-
