Due to legacy reasons, libyuv uses a root_dir variable in the DEPS file. It was used to make the bots checkout into a 'src' dir instead of 'libyuv', in order to get some tools working that had hard-coded assumptions on the name 'src' of the top-level directory. This changes all those dirs to be named 'src', which is needed to get tools_libyuv/autoroller/roll_deps.py to work while keeping the buildbot infrastructure working.

# 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.
|
|
|
|
## Getting the Code
|
|
|
|
Create a working directory, enter it, and run:
|
|
|
|
gclient config --name src https://chromium.googlesource.com/libyuv/libyuv
|
|
gclient sync
|
|
|
|
Then you'll get a .gclient file like:
|
|
|
|
solutions = [
|
|
{ "name" : "src",
|
|
"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" : "src",
|
|
"url" : "https://chromium.googlesource.com/libyuv/libyuv",
|
|
"deps_file" : "DEPS",
|
|
"managed" : True,
|
|
"custom_deps" : {
|
|
},
|
|
"safesync_url": "",
|
|
},
|
|
];
|
|
target_os = ["android", "linux"];
|
|
|
|
Then run:
|
|
|
|
export GYP_DEFINES="OS=android"
|
|
gclient sync
|
|
|
|
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
|
|
