如何在 CPU 为 3865U 的小主机上启用 Jellyfin 的硬解功能

[ZGeek]

如题：硬件总是报遇到致命错误 docker 镜像为：nyanmisaka/jellyfin:lastest ffmpeg 的报错日志为:

别折腾了 哈哈

[ZGeek]

@colincat 怎么了

[A3m0n]

启动容器的时候需要把显卡设备传进去。

例如：/dev/dri/renderD128

[ZGeek]

@A3m0n 传进去了的

[qiaoqiao1235]

要在外面给权限
chmod 777 /dev/dri/renderD128
我用 plex 是可以的

[colincat]

@ZGeek 没啥意思。

[Suaxi]

docker-compose.yml 或者 docker run 命令里加上 root 权限试试

privileged: true

[Panameragt]

以前折腾过很久，成功后感觉真没啥意思

我觉得还蛮有用的，硬解在看一些不得不转码的视频 cpu 占用很低。
- 进容器 ls /dev/dri 看看文件是否正确传进去。
日记里似乎有 qsv ，硬解先选择兼容性好的 vaapi 试试，而非 qsv 。
