# 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

Some functions are symmetric (e.g. ARGBToBGRA is the same as BGRAToARGB, so its a macro).
ARGBBlend expects preattenuated ARGB. The R,G,B are premultiplied by alpha. Other functions don't care.
# RGB24 and RAW
There are 2 RGB layouts - RGB24 (aka 24BG) and RAW
RGB24 is B,G,R in memory
RAW is R,G,B in memory
# AR30 and XR30
AR30 is 2 10 10 10 ARGB stored in little endian order.

The 10 bit RGB values range from 0 to 1023.
XR30 is the same as AR30 but with no alpha channel.
# NV12 and NV21
NV12 is a biplanar format with a full sized Y plane followed by a single
chroma plane with weaved U and V values.
NV21 is the same but with weaved V and U values.
The 12 in NV12 refers to 12 bits per pixel. NV12 has a half width and half
height chroma channel, and therefore is a 420 subsampling.
NV16 is 16 bits per pixel, with half width and full height. aka 422.
NV24 is 24 bits per pixel with full sized chroma channel. aka 444.
