OH6.1移植DLNA

DLNA的移植涉及到以下几个方面：

1. 依赖libupnp（third_party/libupnp）

https://gitcode.com/ohos-oneconnect/third_party_libupnp

需要修改以下的JSON文件：

build/bundle.sjon文件，在third_party选项中加入"libupnp"

build/third_party_allow_list.son文件中加入"libupnp"

2. 依赖libjpeg-turbo（third_party/libjpeg-turbo）

需要修改BUILD.gn文件：

third_party/libjpeg-turbo/BUILD.gn文件中，在visibility选项中加入

"//foundation/CastEngine/castengine_dlna/dmr/service:cast_engine_dmr",

3. castengine_dlna（foundation/CastEngine/castengine_dlna）

https://gitcode.com/ohos-oneconnect/castengine_dlna/tree/OpenHarmony-5.1.0-Release

（1）需要修改vendor/goke/gk6780v100/config.json文件：

在castplus子系统中增加cast_engine_dlna组件

{

"component": "cast_engine_dlna",

"features": []

}

（2）需要修改foundation/CastEngine/castengine_dlna/dmr/etc/init/cast_engine_dmr.cfg文件

在cast_engine_dmr.cfg文件中的services的permission中加入后台启动权限和启动不可见组件权限，以便正常拉起投屏APP。

"ohos.permission.START_ABILITIES_FROM_BACKGROUND",

"ohos.permission.START_INVISIBLE_ABILITY"

4. cast_engine_dmr服务的group和passwd配置

需要修改base/startup/init/services/etc/group文件和base/startup/init/services/etc/passwd文件

base/startup/init/services/etc/group文件中加入 cast_engine_dmr:x:1603:

base/startup/init/services/etc/passwd文件中加入 cast_engine_dmr:x:1603:1603:::/bin/false

5. selinux的配置（base/security/selinux_adapter）

以下是相关selinux的patch包:

6. 总结

以上的步骤是在OH6.1上移植的，如果是在OH5.1上移植的话，那么libjpeg-turbo这一步不需要修改，castengine_dlna本身的cast_engine_dmr.cfg也不需要修改，相关的selinux也大致差不多。

GK6780升级oh 6.1 release适配兆通微9612U模组WIFI驱动实践总结

一、先拿到驱动源码 1、咨询模组厂商，让他们提供即可比如我这里获取到的驱动源码包名称是：ZTOP_ACEV100_Android_wifi_bt_20260326214112.tar.gz，解压后的目录截图如下 2、也可以直接取已经编好的ko文件与bin文件直接和项目一起编译（如此就跳过步骤一、步骤二）二、编译模组（如果是直接拿的ko文件则跳过这一步）
