编译分三大步：
一、配置必须的环境
二、下载
三、编译
一、准备工作
1.Win10系统，必须64位，至少8GB的RAM，我采用win10 64位，16GRAM
2.比较新的VS,最近免费的社区版（编译不同版本要求不一样，具体看Cef官网帮助，我用的是VS2019），需要安装“C++桌面组件” 和 “MFC和ATL支持”,最好安装在默认路径
3.Win10 SDK（VS2019中有）
4.至少200G剩余空间，NTFS文件系统，部分文件超过4G，部分资料显示最少60G，编译结束后发现远超60G
5.设置系统区域为英语（美国）。（控制面板-区域-管理-更改系统区域设置-英语（美国）），设置完需要重启
6.创建工作目录，路径不能包含空格及特殊字符。例如f:\cef
7.下载编译工具包，解压至工作目录。例如f:\cef\depot_tools
建议从git仓库获取最新的：
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
8.下载编译脚本至工作目录。例如f:\cef
9.在工作目录下创建源码目录。例如f:\cef\source
10.安装ninja,并加添到系统环境变量下载地址:ninja
11.一个稳定的 VPN 网络可以让你快速下载 CEF 和 Chromium 代码
二、配置环境变量
1.配置depot_tools
2.配置ninja环境变量
三、配置下载脚本并下载
新建一个 bat脚本并命名为 git_4430.bat
在脚本中写入如下代码
set CEF_USE_GN=1 set GN_DEFINES=is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome set GYP_DEFINES=buildtype=Official set GYP_MSVS_VERSION=2019 set CEF_ARCHIVE_FORMAT=tar.bz2 set GN_ARGUMENTS=--ide=vs2019 --sln=cef --filters=//cef/* python automate-git.py --download-dir=F:\cef\source --depot-tools-dir=F:\cef\depot-tools --branch=4430 --force-clean --no-build --no-distrib pause
代理运行(需要管理员)：
echo proxy setup ... echo -------------------- netsh winhttp set proxy 127.0.0.1:10809 set https_proxy=http://127.0.0.1:10809 set http_proxy=http://127.0.0.1:10809 echo env setup ... set CEF_USE_GN=1 set GN_DEFINES=is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome set GYP_DEFINES=buildtype=Official set GYP_MSVS_VERSION=2019 set CEF_ARCHIVE_FORMAT=tar.bz2 set GN_ARGUMENTS=--ide=vs2019 --sln=cef --filters=//cef/* python automate-git.py --download-dir=F:\cef\source --depot-tools-dir=F:\cef\depot-tools --branch=4430 --force-clean --no-build --no-distrib pause
10809端口要改成自己实际的
两个脚本根据实际情况选择其一
GN_DEFINES 参数介绍：
ffmpeg_branding和proprietary_codecs表示开启多媒体编解码支持，但默认仅支持一小部分，后面介绍如何支持更多。is_official_build决定了是否是编译正式版本，指定该参数为 true 基本上都是为了产品发布使用，同时也会在创建解决方案的时候生成带有 sandbox 的解决方案（如 Release_GN_x86_sandbox），而不指定这个参数是没有的。如果你不是为了贡献代码，那默认这个都加上吧。use_jumbo_build官方资料默认指定，表示是否启用试验性的 jumbo 编译，编译过程会加快很多（至少快 1 小时），但是占用 CPU 和内存（尤其是内存）会剧增。is_component_build官方资料默认指定，但我们没有开启，这个参数表示是否启用组件化编译，设置为 true 以后，base、ffmpeg 等等都会被编译为动态库，使用时也是动态链接，编译出来的 cef_sandbox.lib 只有几兆大小，并且你需要复制很多 dll 文件到项目目录下才能运行。
automate-git.py 参数介绍
--branch表示你要下载哪个版本的代码，CEF 每个版本都有固定的分支，你去 CEF 项目页查看分支名称指定即可，这里我们编译 2019年9月份目前最新的版本 3809。--no-build表示只下载代码而不编译，这里只为下载代码，我们还要修改支持多媒体的参数，所以不进行编译--no-distrib不执行打包项目，这里只为下载代码，我们还要修改支持多媒体的参数，所以不进行打包--force-clean如果你曾经执行过这个脚本，可能会出错，则加上这个参数，它执行清理残留文件（你也可以手动在 chromium 源码目录执行 git clean -xdf 来清理目录中的多余内容）。automate-git.py 的其他参数可以手动执行
python automate-git.py --help来查看
注：
如果VPN不太稳定，可能会经常中断，造成脚本运行错误，重新运行脚本即可，源码主要有三部分，depot_tools源码cef源码和chromium源码，如果发现相应部分的源码已经同步完成，可以分别使用--no-depot-tools-update, --no-cef-update, --no-chromium-update 来不进行相应部分的代码更新。
自动构建脚本在下载源码时，并没有进度提示，比如在下载chromium/src目录时时间会非常长，会一直提示still working on src...，请耐心等待。
3.cmd（管理员权限运行）git_4430.bat脚本
完整目录结构： f:/ cef/ automate-git.py depot_tools/ source/
四、修改文件使得CEF支持MP4能力
修改：source\chromium\src\third_party\ffmpeg\chromium\scripts\build_ffmpeg.py 文件
configure_flags['Chrome'].extend([ '--enable-decoder=aac,h264,mp3', '--enable-demuxer=aac,mp3,mov', '--enable-parser=aac,h264,mpegaudio', ])
改为
configure_flags['Chrome'].extend([ '--enable-decoder=aac,h264,mp3,mpeg4,amrnb,amrwb,flv', '--enable-demuxer=aac,mp3,mov,avi,amr,flv', '--enable-parser=aac,h264,mpegaudio,mpeg4video,h263', ])
分别打开:
f:\cef\source\chromium\src\third_party\ffmpeg\chromium\config\Chrome\win\ia32\config.h
f:\cef\source\chromium\src\third_party\ffmpeg\chromium\config\Chrome\win\x64\config.h
在原有配置宏FFMPEG_CONFIGURATION里增加以下：
--enable-decoder=’rv10,rv20,rv30,rv40,cook,h263,h263i,mpeg4,msmpeg4v1,msmpeg4v2,msmpeg4v3,amrnb,amrwb,ac3,flv’ --enable-demuxer=’rm,mpegvideo,avi,avisynth,h263,aac,amr,ac3,flv,mpegts,mpegtsraw’ --enable-parser=’mpegvideo,rv30,rv40,h263,mpeg4video,ac3’
注：但在90.6.7中我看到FFMPEG_CONFIGURATION节点是被禁用的
因在90.6.7中看到FFMPEG_CONFIGURATION是被禁用因此我们使用下面这种方式
分别修改:
f:\cef\source\chromium\src\third_party\ffmpeg\chromium\config\Chrome\win\ia32\config.h
f:\cef\source\chromium\src\third_party\ffmpeg\chromium\config\Chrome\win\x64\config.h
把部分#define 由0改为1
#define CONFIG_FLV_DECODER 1 #define CONFIG_H263_DECODER 1 #define CONFIG_H263I_DECODER 1 #define CONFIG_MPEG4_DECODER 1 #define CONFIG_MPEGVIDEO_DECODER 1 #define CONFIG_MSMPEG4V1_DECODER 1 #define CONFIG_MSMPEG4V2_DECODER 1 #define CONFIG_MSMPEG4V3_DECODER 1 #define CONFIG_RV10_DECODER 1 #define CONFIG_RV20_DECODER 1 #define CONFIG_RV30_DECODER 1 #define CONFIG_RV40_DECODER 1 #define CONFIG_AC3_DECODER 1 #define CONFIG_AMRNB_DECODER 1 #define CONFIG_AMRWB_DECODER 1 #define CONFIG_COOK_DECODER 1 #define CONFIG_SIPR_DECODER 1 #define CONFIG_FLV_ENCODER 1 #define CONFIG_H263_ENCODER 1 #define CONFIG_MPEG4_ENCODER 1 #define CONFIG_MSMPEG4V2_ENCODER 1 #define CONFIG_MSMPEG4V3_ENCODER 1 #define CONFIG_RV10_ENCODER 1 #define CONFIG_RV20_ENCODER 1 #define CONFIG_AAC_ENCODER 1 #define CONFIG_AC3_ENCODER 1 #define CONFIG_AC3_PARSER 1 #define CONFIG_COOK_PARSER 1 #define CONFIG_H263_PARSER 1 #define CONFIG_MPEG4VIDEO_PARSER 1 #define CONFIG_MPEGVIDEO_PARSER 1 #define CONFIG_RV30_PARSER 1 #define CONFIG_RV40_PARSER 1 #define CONFIG_SIPR_PARSER 1 #define CONFIG_AC3_DEMUXER 1 #define CONFIG_AMR_DEMUXER 1 #define CONFIG_AMRNB_DEMUXER 1 #define CONFIG_AMRWB_DEMUXER 1 #define CONFIG_AVI_DEMUXER 1 #define CONFIG_AVISYNTH_DEMUXER 1 #define CONFIG_FLV_DEMUXER 1 #define CONFIG_H263_DEMUXER 1 #define CONFIG_H264_DEMUXER 1 #define CONFIG_MPEGTS_DEMUXER 1 #define CONFIG_MPEGTSRAW_DEMUXER 1 #define CONFIG_MPEGVIDEO_DEMUXER 1 #define CONFIG_RM_DEMUXER 1 #define CONFIG_AC3_MUXER 1 #define CONFIG_AMR_MUXER 1 #define CONFIG_AVI_MUXER 1 #define CONFIG_FLV_MUXER 1 #define CONFIG_H263_MUXER 1 #define CONFIG_H264_MUXER 1 #define CONFIG_MPEGTS_MUXER 1 #define CONFIG_RM_MUXER 1
因为改的比较多，这里我们通过python的脚本进行帮我们修改
1.新建一个mp4_support.txt把上面的内容复制进去
2.新建一个update_mp4.py的脚本，内容如下：
## 第一参数为上面要修改的#define 的文件路径，第二参数为 F:\cef\source\chromium\src\third_party\ffmpeg\chromium\config\Chrome\win\ia32\config.h
import sys
import shutil
import re
import os
def Replace(change,content):
str_array = re.findall("#define\s\w+\s",change)
str_replace =str_array[0]
str_replace+="0"
str_dest =str_array[0]
str_dest+="1"
return content.replace(str_replace,str_dest)
if len(sys.argv) > 2 :
src_file_name =sys.argv[1]
dest_file_name=sys.argv[2]
else:
src_file_name =raw_input("Please input src file path name:").replace("\r","")
dest_file_name =raw_input("Please input dest file path name:").replace("\r","")
file_src_handle = open(src_file_name,"r")
file_src_lines = file_src_handle.readlines()
file_src_handle.close()
file_dest_handle = open(dest_file_name,"r")
dest_file_content = file_dest_handle.read()
file_dest_handle.close()
for line in file_src_lines:
dest_file_content = Replace(line,dest_file_content)
write_file_path = os.getcwd()+"\\"+ os.path.basename(dest_file_name)
ready_copy = open(write_file_path,"w")
ready_copy.write(dest_file_content)
ready_copy.close()
shutil.copy(write_file_path,dest_file_name)
os.remove(write_file_path)
print("Support mp4 Success!!!")3.新建一个bat 脚本用于启动我们的update_mp4.py脚本(也可以直接通过cmd进行启动) bat脚本内容如下:
python update_mp4.py F:/cef/script/mp4_support.txt F:/cef/source/chromium/src/third_party/ffmpeg/chromium/config/Chrome/win/ia32/config.h pause
python update_mp4.py F:/cef/script/mp4_support.txt F:/cef/source/chromium/src/third_party/ffmpeg/chromium/config/Chrome/win/x64/config.h pause
4.分别执行两个脚本
目录如下：
五、创建编译脚本
新建两个脚本分别对应x86、x64
build_x64_4430.bat文件内容如下：
set CEF_USE_GN=1 set GN_DEFINES=is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome set GYP_DEFINES=buildtype=Official set GYP_MSVS_VERSION=2019 set CEF_ARCHIVE_FORMAT=tar.bz2 set DEPOT_TOOLS_WIN_TOOLCHAIN=0 set GYP_GENERATORS=ninja,msvs-ninja set GN_ARGUMENTS=--ide=vs2019 --sln=cef --filters=//cef/* set WIN_CUSTOM_TOOLCHAIN=1 set CEF_VCVARS=none set GYP_MSVS_OVERRIDE_PATH=C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise set SDK_ROOT=C:\Program Files (x86)\Windows Kits\10 set PATH=C:\Program Files (x86)\Windows Kits\10\bin\10.0.19041.0\x64;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\bin\HostX64\x64;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Redist\MSVC\14.13.26020\x64\Microsoft.VC141.CRT;%PATH% set LIB=C:\Program Files (x86)\Windows Kits\10\Lib\10.0.19041.0\um\x64;C:\Program Files (x86)\Windows Kits\10\Lib\10.0.19041.0\ucrt\x64;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\lib\x64;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\atlmfc\lib\x64;%LIB% set INCLUDE=C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\um;C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\ucrt;C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\shared;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\include;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\atlmfc\include;%INCLUDE% set VS_CRT_ROOT=C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\crt\src\vcruntim python automate-git.py --download-dir=f:\cef\source --depot-tools-dir=F:\cef\depot-tools --branch=4430 --x64-build --no-update --build-log-file --verbose-build --force-distrib --force-build --no-debug-build pause
build_x86_4430.bat文件内容如下：
set CEF_USE_GN=1 set GN_DEFINES=is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome set GYP_DEFINES=buildtype=Official set GYP_MSVS_VERSION=2019 set CEF_ARCHIVE_FORMAT=tar.bz2 set DEPOT_TOOLS_WIN_TOOLCHAIN=0 set GYP_GENERATORS=ninja,msvs-ninja set GN_ARGUMENTS=--ide=vs2019 --sln=cef --filters=//cef/* set WIN_CUSTOM_TOOLCHAIN=1 set CEF_VCVARS=none set GYP_MSVS_OVERRIDE_PATH=C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise set SDK_ROOT=C:\Program Files (x86)\Windows Kits\10 set INCLUDE=C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\um;C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\ucrt;C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\shared;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\include;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\atlmfc\include;%INCLUDE% set PATH=C:\Program Files (x86)\Windows Kits\10\bin\10.0.19041.0\x86;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\bin\HostX64\x86;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\bin\HostX64\x64;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Redist\MSVC\14.29.30037\x64\Microsoft.VC141.CRT;%PATH% set LIB=C:\Program Files (x86)\Windows Kits\10\Lib\10.0.19041.0\um\x86;C:\Program Files (x86)\Windows Kits\10\Lib\10.0.19041.0\ucrt\x86;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\lib\x86;C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\atlmfc\lib\x86;%LIB% set VS_CRT_ROOT=C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.29.30037\crt\src\vcruntim python automate-git.py --download-dir=f:\cef\source --depot-tools-dir=F:\cef\depot-tools --branch=4430 --no-update --build-log-file --verbose-build --force-distrib --force-build --no-debug-build pause
注:根据自己的VS版本、路径，Win10 SDK版本、路径进行对应更改
备注：bat中的选项可以有：
--download-dir 源码下载目录
--depot-tools-dir 工具包目录
--branch 源码分支(默认trunk主分支)
--checkout 指定patch版本（默认最近提交)
--no-build 下载完不自动开始编译（我们需要修改编译配置)
--no-update 确定源码下载完毕仅重新编译时使用
--force-build 强制编译（发现在有成功编译的时候再编译不会执行，可以加上这个
--no-debug-build 只编译release版本
--no-release-build 只编译debug版本
六、执行对应该环境的脚本进入漫长的等待
七.编译完成
输出目录为source\chromium\src\out\Release_GN_x86 和 source\chromium\src\cef\binary_distrib，Release_GN_x86下有cefclient.exe可以测试，binary_distrib下有cef_binary_90.6.7+g19ba721+chromium-90.0.4430.212_windows32
通过cmd 运行cefclient.exe -url=http://html5test.com -single-process 结果如下：
