群晖918 docker命令行方式安装jellyfin并开启GPU硬解的方法

问题

jellyfin是一个开源的视频管理平台，比群晖自带的video station功能更强，但是直接通过918的docker界面直接安装的jellyfin，由于没有进行device的映射，因此实际上是没有启动硬解的。

表面上jellyfin的控制台开启了VAAPI，但实际上在后台一直在报错。

后台报错如下：

原因

这是由于群晖的docker控制台的限制，群晖核显/dev/dri/renderD128并没有真正映射到容器中。

解决方案

ssh到群晖后台，利用root账户启动docker，例如：

核心就在于--device /dev/dri/renderD128:/dev/dri/renderD128 --device /dev/dri/card0:/dev/dri/card0这两句，之后就可以愉快的玩耍啦，实测一台白918和另一台蜗牛j1900安装的黑群晖均可以硬解。而且后续通过群晖docker控制台停止、重启该容器，都不影响硬解。

更新：截止2020年11月17日，jellyfin已更新至10.6.4
