CefSharp音视频编译与免费下载

注：Cefharp 音频和视频播放编译，生成相应的dll文件，从而支持项目开发。 建议编译至少 16G 的 RAM和至少 250G 的 SSD。该脚本以 E 盘为例，您需要在 E 盘上手动创建 cef 文件夹。禁止在转载后通过发布其他平台向用户收取下载费用。

md E:\cef\chromium\src

1.版本选择

配置 Web 地址：
https://bitbucket.org/chromiumembedded/cef/wiki/BranchesAndBuilding.md

选择所需的版本并配置环境。

例如：install vs2022，选择相应的sdk，10.0.22621.2428。
VS2022 requires the selection of C++.

2.网络选择

选择适当的网络来访问 Internet，然后根据网络工具，可以设置代理。 例如，建议每次打开cmd时手动执行它，以实际端口号为准。

set HTTP_PROXY=http://127.0.0.1:7890
set HTTPS_PROXY=http://127.0.0.1:7890

3.环境初始化

以管理员身份运行 cmd 并进入批处理脚本所在的目录，在cmd窗口执行批处理脚本。

:: Disable automatic update of depot_tools
setx DEPOT_TOOLS_UPDATE "0"

:: Using a locally installed version of Visual Studio
setx DEPOT_TOOLS_WIN_TOOLCHAIN "0"

:: GN Build Tool
set CEF_USE_GN=1
:: Creating a Project with VS2022
set GN_ARGUMENTS=--ide=vs2022 --sln=cef --filters=//cef/*
:: Use the official build and add ffmpeg audio/video decoding
set GN_DEFINES=is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome chrome_pgo_phase=0
set GYP_DEFINES=buildtype=Official

set GYP_GENERATORS=ninja,msvs-ninja
set GYP_MSVS_VERSION=2022

set SDK_VERSION=10.0.22621.0

for /f "tokens=3,*" %i in ('reg query HKCU\Environment /v Path') do setx Path "E:\cef\depot_tools\;%i%j"

命令行执行 0.environment_init.bat

4.CEF下载

根据选择的分支执行，这里以 6422 分支为例

cd E:\cef
::Clone the source code and switch to the 6422 branch
git clone https://bitbucket.org/chromiumembedded/cef.git -b 6422

命令行执行 1.downing_cef.bat

5.Chromium下载

根据所选分支的CHROMIUM_BUILD_COMPATIBILITY.txt检查版本。

# The Chromium Embedded Framework (CEF) project is built on top of the Chromium
# project source tree. Chromium should be updated to the URL and revision listed
# below before building CEF. Chromium compatibility information for older CEF
# revisions is available by viewing this file's change history.
#
# Instructions for building CEF are available at:
# https://bitbucket.org/chromiumembedded/cef/wiki/BranchesAndBuilding

{
  'chromium_checkout': 'refs/tags/125.0.6422.142',
  'depot_tools_checkout': '3e4ab13934'
}

cd E:\cef\chromium
::  (cef 6422 branch corresponds to chromiun tag: 125.0.6422.142)
git clone https://chromium.googlesource.com/chromium/src.git -b 125.0.6422.142 --depth 1

命令行执行2.downing_chromium.bat

6.depot_tools下载

cd E:\cef
:: Download depot_tools tool
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
cd E:\cef\depot_tools
:: Temporary permission to update
set DEPOT_TOOLS_UPDATE=1
:: depot_tools batch script Update_Depot_tools.bat
update_depot_tools.bat
:: prohibit updating
set DEPOT_TOOLS_UPDATE=0
:: checkout,(CEF 6422 branch corresponds to depot_tools commit ID: 3e4ab13934)
checkout 3e4ab13934

命令行执行 3.downing_depot_tools

7.同步

cd E:\cef\chromium

:: Create the .gclient file with the command
gclient config  https://chromium.googlesource.com/chromium/src.git --unmanaged

gclient sync --nohooks --no-history

set DEPOT_TOOLS_WIN_TOOLCHAIN=0

@echo "gclient runhooks"
gclient runhooks

建议手动执行4.chromium_client剩下的命令

8.构建项目

cd E:\cef\chromium\src\cef
set CEF_USE_GN=1
set GN_ARGUMENTS=--ide=vs2022 --sln=cef --filters=//cef/*
set GN_DEFINES=is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome chrome_pgo_phase=0
set GYP_DEFINES=buildtype=Official
set GYP_GENERATORS=ninja,msvs-ninja
set GYP_MSVS_VERSION=2022
set CEF_ARCHIVE_FORMAT=tar.bz2
set VS_CRT_ROOT=D:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.40.33807\crt
set WIN_CUSTOM_TOOLCHAIN=1
::set CEF_VCVARS=none
set GYP_MSVS_OVERRIDE_PATH=D:\Program Files\Microsoft Visual Studio\2022\Professional
set MSVC_VERSION=14.40.33807
set SDK_ROOT=D:\Program Files (x86)\Windows Kits\10
set WINDOWSSDKDIR=D:\Program Files (x86)\Windows Kits\10
set SDK_VERSION=10.0.22621.0

:: create project
call cef_create_projects.bat

cef需要移动到chromium/src目录下，手动执行5.build_project

9.CEF编译

根据计算机配置，相对编译时间更长，8~10小时，甚至更长。

cd E:\cef\chromium\src
ninja -C out\Release_GN_x64_sandbox cef_sandbox
ninja -C out/Release_GN_x64 cef

命令行手动执行6.cef_compile

10.打包生成

cd E:\cef\chromium\src\cef\tools
set CEF_VCVARS=none
set CEF_ARCHIVE_FORMAT=tar.bz2
::  --minimal（可选择stable版本等等）
make_distrib.bat --ninja-build --no-docs --x64-build --no-symbols --minimal

11.结果展示

使用生成的 dll 测试站点

测试 h264 是否打开，即音频/视频播放。
