libyuv編譯（各平台）

最近用到視頻格式轉碼，發現Google的開源庫 libyuv 很好用，所以記錄下編譯過程

直接貼 官網的編譯流程

https://chromium.googlesource.com/libyuv/libyuv/+/master/docs/getting_started.md

不過我得吐槽一下，我特麼就想編譯個libyuv 你特麼非要讓我把chrome項目check 下來是幾個意思。。。。如果沒猜錯 應該是好幾個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.

說明：依賴工具，Google的這套東西還是比較好用的，首先要安裝depottools 這點不多說，命令列就行，最重要的是在下載完成之後要有

export PATH=`pwd`/depot_tools:"$PATH" 命令使能這個工具 Getting the Code

Create a working directory, enter it, and run:

gclient config https://chromium.googlesource.com/libyuv/libyuvgclient sync

說明：設定與同步代碼，裡面內建指令碼，關於代碼如何同步的就無需關心了。

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 ;target_os=['ios']; to your OSX .gclient and run GYP_DEFINES="OS=ios" gclient sync.

Browse the Git reprository: https://chromium.googlesource.com/libyuv/libyuv/+/master Android

For Android add ;target_os=['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:

export GYP_DEFINES="OS=android"gclient sync

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: gclient runhooks

To get just the source (not buildable): git clone https://chromium.googlesource.com/libyuv/libyuv Building the Library and Unittests Windows

CentOS

On CentOS 32 bit the following work around allows a sync:

export GYP_DEFINES="host_arch=ia32"gclient sync

Windows Shared Library

Modify libyuv.gyp from ‘static_library’ to ‘shared_library’, and add ‘LIBYUV_BUILDING_SHARED_LIBRARY’ to ‘defines’.

gclient runhooks

After this command follow the building the library instructions above.
