最近用到视频格式转码,发现谷歌的开源库 libyuv 很好用,所以记录下编译过程
直接贴 官网的编译流程
https://chromium.googlesource.com/libyuv/libyuv/+/master/docs/getting_started.md
不过我得吐槽一下,我特么就想编译个libyuv 你特么非要让我把chrome项目check 下来是几个意思。。。。如果没猜错 应该是好几个g
Getting Started
How to get and build the libyuv code.
Pre-requisites
You‘ll need to have depot tools installed: https://www.chromium.org/developers/how-tos/install-depot-tools Refer to chromium instructions for each platform for other prerequisites.
说明:依赖工具,谷歌的这套东西还是比较好用的,首先要安装depottools 这点不多说,命令行就行,最重要的是在下载完成之后要有
export PATH=`pwd`/depot_tools:"$PATH" 命令使能这个工具
Getting the Code
Create a working directory, enter it, and run:
说明:设置与同步代码,里面自带脚本,关于代码如何同步的就无需关心了。
Then you‘ll get a .gclient file like:
solutions = [ { "name" : "libyuv", "url" : "https://chromium.googlesource.com/libyuv/libyuv", "deps_file" : "DEPS", "managed" : True, "custom_deps" : { }, "safesync_url": "", },];
For iOS add ios‘];
to your OSX .gclient and run Browse the Git reprository: https://chromium.googlesource.com/libyuv/libyuv/+/master
Android
For Android add android‘];
to your Linux .gclient
solutions = [ { "name" : "libyuv", "url" : "https://chromium.googlesource.com/libyuv/libyuv", "deps_file" : "DEPS", "managed" : True, "custom_deps" : { }, "safesync_url": "", },];target_os = ["android", "unix"];
Then run:
Caveat: Theres an error with Google Play services updates. If you get the error “Your version of the Google Play services library is not up to date”, run the following: cd chromium/src ./build/android/play_services/update.py download cd ../..
For Windows the gclient sync must be done from an Administrator command prompt.
The sync will generate native build files for your environment using gyp (Windows: Visual Studio, OSX: XCode, linux: make). This generation can also be forced manually: To get just the source (not buildable): git clone https://chromium.googlesource.com/libyuv/libyuv
Building the Library and Unittests
Windows
Building with clangcl
OSX
Clang 64 bit shown. Remove clang=1
for GCC and change x64 to ia32 for 32 bit.
iOS
http://www.chromium.org/developers/how-tos/build-instructions-ios
Add to .gclient last line: target_os=[‘ios‘];
armv7
arm64
both armv7 and arm64 (fat)
simulator
Android
https://code.google.com/p/chromium/wiki/AndroidBuildInstructions
Add to .gclient last line: target_os=[‘android‘];
armv7
arm64
ia32
mipsel
arm32 disassembly:
arm64 disassembly:
Running tests:
Running test as benchmark:
Running test with C code:
Building with GN
Building Offical with GN
Linux
CentOS
On CentOS 32 bit the following work around allows a sync:
Windows Shared Library
Modify libyuv.gyp from ‘static_library’ to ‘shared_library’, and add ‘LIBYUV_BUILDING_SHARED_LIBRARY’ to ‘defines’.
After this command follow the building the library instructions above.
If you get a compile error for atlthunk.lib on Windows, read http://www.chromium.org/developers/how-tos/build-instructions-windows
Build targets
Building the Library with make
Linux
Building the Library with cmake
Install cmake: http://www.cmake.org/
Default debug build:
Release build/install
Windows 8 Phone
Pre-requisite:
- Install Visual Studio 2012 and Arm to your environment.
Then:
or with Visual Studio 2013:
Windows Shared Library
Modify libyuv.gyp from ‘static_library’ to ‘shared_library’, and add ‘LIBYUV_BUILDING_SHARED_LIBRARY’ to ‘defines’. Then run this.
After this command follow the building the library instructions above.
If you get a compile error for atlthunk.lib on Windows, read http://www.chromium.org/developers/how-tos/build-instructions-windows
64 bit Windows
ARM Linux
export GYP_DEFINES="target_arch=arm"export CROSSTOOL=`<path>`/arm-none-linux-gnueabiexport CXX=$CROSSTOOL-g++export CC=$CROSSTOOL-gccexport AR=$CROSSTOOL-arexport AS=$CROSSTOOL-asexport RANLIB=$CROSSTOOL-ranlibgclient runhooks
Running Unittests
Windows
OSX
Linux
Replace --gtest_filter=“*” with specific unittest to run. May include wildcards. e.g.
CPU Emulator tools
Intel SDE (Software Development Emulator)
Pre-requisite: Install IntelSDE for Windows: http://software.intel.com/en-us/articles/intel-software-development-emulator
Then run:
Memory tools
Running Dr Memory memcheck for Windows
Pre-requisite: Install Dr Memory for Windows and add it to your path: http://www.drmemory.org/docs/page_install_windows.html
Running UBSan
See Chromium instructions for sanitizers: https://www.chromium.org/developers/testing/undefinedbehaviorsanitizer
Sanitizers available: TSan, MSan, ASan, UBSan, LSan
Running Valgrind memcheck
Memory errors and race conditions can be found by running tests under special memory tools. [Valgrind] 1 is an instrumentation framework for building dynamic analysis tools. Various tests and profilers are built upon it to find memory handling errors and memory leaks, for instance.
Then run:
For more information, see http://www.chromium.org/developers/how-tos/using-valgrind
Running Thread Sanitizer (TSan)
For more info, see http://www.chromium.org/developers/how-tos/using-valgrind/threadsanitizer
Running Address Sanitizer (ASan)
For more info, see http://dev.chromium.org/developers/testing/addresssanitizer
Benchmarking
The unittests can be used to benchmark.
Windows
Linux and Mac
Indicates 0.547 ms/frame for 1280 x 720.
