## 前期准备

### 1. 安装 AME 并激活

### 2. Patch synocodectool

> 脚本来自：https://github.com/wirgen/synocodectool-patch

执行下面的脚本：

```shell
#!/bin/bash

wget https://raw.githubusercontent.com/wirgen/synocodectool-patch/master/patch.sh
chmod +x patch.sh
./patch.sh -p
```

执行输出如下，这里需要输入：`2`，然后按回车

最终输出如下：

```
Detected DSM version: 7.2 64570-1
Patch for DSM Version (7.2 64570-1) AVAILABLE!
Available binaries to patch/restore:
1) /usr/syno/bin/synocodectool
2) /volume1/@appstore/VideoStation/bin/synocodectool
3) /volume1/@appstore/CodecPack/bin/synocodectool
4) Quit
Please choose which binary you want to patch/restore:2

## VideoStation 硬解配置

由于 SA6400 是 AMD 机型，默认 VideoStation 是不支持开启硬解的，需要相关的补丁才行，理论上本教程里的补丁，适用于所有想使用英特尔核显来硬解的机型。

## 操作步骤

### 1. 更新 VideoStation 相关补丁

> 在 VideoStation 3.1.0-3153 上测试通过

> 硬解的前提是 AME 正常激活，同时 synocodectool 也正确 Patch 了，请自行研究

> 该教程还需要继续优化，不能正常硬解属于正常情况，可以留言反馈无法硬解的环境、以及影片信息

> 该教程引用了 SynoCommunity 的 `ffmpeg` 套件，以及 `VideoStation-FFMPEG-Patcher` 补丁

执行下面的脚本后，可以在 VideoStation 设置的`高级选项`里，自由切换是否使用`硬件转码`

```shell
#!/bin/bash

synopkgctl stop VideoStation

if [ ! -f /usr/sbin/elf-func-overwrite ]; then
  wget -O /usr/sbin/elf-func-overwrite -c https://alist.jim.plus/d/public/synology/tools/elf-func-overwrite
  chmod +x /usr/sbin/elf-func-overwrite
fi

elf-func-overwrite /var/packages/VideoStation/target/lib/libvideostation_webapi.so _ZN5libvs4util13PlatformUtils12IsGeminiLakeEv "B8 01 00 00 00 C3"
chown VideoStation:VideoStation /var/packages/VideoStation/target/lib/libvideostation_webapi.so

elf-func-overwrite /var/packages/VideoStation/target/lib/libsynovte.so _ZN5libvs4util13PlatformUtils12IsGeminiLakeEv "B8 01 00 00 00 C3"
chown VideoStation:VideoStation /var/packages/VideoStation/target/lib/libsynovte.so

elf-func-overwrite /var/packages/VideoStation/target/ui/cgi/advanced_manage.cgi _ZN5libvs4util13PlatformUtils12IsGeminiLakeEv "B8 01 00 00 00 C3"
chown VideoStation:VideoStation /var/packages/VideoStation/target/ui/cgi/advanced_manage.cgi

wget -O /var/packages/VideoStation/target/etc/TransInfo_VAAPI_HLS https://alist.jim.plus/d/public/synology/config/VideoStation/TransInfo_VAAPI_HLS-3.1.0-3153.json

ffmpeg_status=$(synopkg status ffmpeg | jq .status)
if [ "$ffmpeg_status" = '"non_installed"' ]; then
   echo install ffmpeg
   wget -O /tmp/ffmpeg.spk -c https://packages.synocommunity.com/ffmpeg/49/ffmpeg.v49.f42661%5Bapollolake-avoton-braswell-broadwell-broadwellnk-broadwellnkv2-broadwellntbap-bromolow-cedarview-denverton-epyc7002-geminilake-grantley-kvmx64-purley-r1000-v1000%5D.spk
   synopkg install /tmp/ffmpeg.spk
   # rm -f /tmp/ffmpeg.spk
fi

curl https://raw.githubusercontent.com/AlexPresso/VideoStation-FFMPEG-Patcher/main/patcher.sh | bash

# disable apparmor check
apparmor=/var/packages/VideoStation/target/apparmor
/usr/syno/etc/rc.sysv/apparmor.sh remove_packages_profile 0 VideoStation
if [ -e "${apparmor}" ]; then
  mv -f "${apparmor}" "${apparmor}.bak"
fi

synopkgctl start VideoStation
```

### 2. 在引导中更新 `apparmor` 配置

> user-config.yml 配置在 arpl 里的路径为：/mnt/p1/user-config.yml

修改引导第一分区下的 user-config.yml，在 `cmdline` 下新增一行 `apparmor.mode: "complain"`，注意前面加两个空格与下面的参数对齐。

下面是样例，供参考。

```yaml
cmdline:
  apparmor.mode: "complain"
  netif_num: "4"
```

修改完毕后重新构建引导，然后进入 VideoStation 设置里重建索引，然后再开启硬解即可。
