Deprecated Builds

Older documentation on build configs which are no longer supported.

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.

Getting the Code

Create a working directory, enter it, and run:

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

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

call "c:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\x86_arm\vcvarsx86_arm.bat"
nmake /f winarm.mk clean
nmake /f winarm.mk

Windows Shared Library

Modify libyuv.gyp from 'static_library' to 'shared_library', and add 'LIBYUV_BUILDING_SHARED_LIBRARY' to 'defines'. Then run this.

gclient runhooks

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

export AS=$CROSSTOOL-as
export RANLIB=$CROSSTOOL-ranlib
gclient runhooks

Running Unittests

OSX

out/Release/libyuv_unittest --gtest_filter="*"

Linux

out/Release/libyuv_unittest --gtest_filter="*"

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.

solutions = [
  { "name"        : "libyuv",
    "url"         : "https://chromium.googlesource.com/libyuv/libyuv",
    "deps_file"   : "DEPS",
    "managed"     : True,
    "custom_deps" : {
       "libyuv/chromium/src/third_party/valgrind": "https://chromium.googlesource.com/chromium/deps/valgrind/binaries",
    },
    "safesync_url": "",
  },
]

Then run:

GYP_DEFINES="clang=0 target_arch=x64 build_for_tool=memcheck" python gyp_libyuv
ninja -C out/Debug
valgrind out/Debug/libyuv_unittest

For more information, see http://www.chromium.org/developers/how-tos/using-valgrind

Running Thread Sanitizer (TSan)

Benchmarking

The unittests can be used to benchmark.

Windows

set LIBYUV_WIDTH=1280
set LIBYUV_HEIGHT=720
set LIBYUV_REPEAT=999
set LIBYUV_FLAGS=-1
out\Release\libyuv_unittest.exe --gtest_filter=*I420ToARGB_Opt

Linux and Mac

LIBYUV_WIDTH=1280 LIBYUV_HEIGHT=720 LIBYUV_REPEAT=1000 out/Release/libyuv_unittest --gtest_filter=*I420ToARGB_Opt

libyuvTest.I420ToARGB_Opt (547 ms)

Indicates 0.547 ms/frame for 1280 x 720.
