# When vpython is invoked, it finds this file and builds a python VirtualEnv,
# containing all of the dependencies described in this file, fetching them from

# 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

# Planar YUV
The following formats contains a full size Y plane followed by 1 or 2
planes for UV: I420, I422, I444, I400, NV21, NV12, I400
The size (subsampling) of the UV varies.
I420, NV12 and NV21 are half width, half height
I422, NV16 and NV61 are half width, full height
I444, NV24 and NV42 are full width, full height
I400 and J400 have no chroma channel.
# Color space
The YUV formats start with a letter to specify the color space. e.g. I420
I = BT.601 limited range
J = BT.601 full range (J = JPEG that uses this)
H = BT.709 limited range (H for HD)
F = BT.709 full range (F for Full range)
U = BT.2020 limited range (U for UHD)
V = BT.2020 full range
For YUV to RGB conversions, a matrix can be passed. See also convert_argh.h
# HDR formats
Planar formats with 10 or 12 bits use the following fourcc:
I010, I012, P010, P012 are half width, half height
I210, I212, P210, P212 are half width, full height
I410, I412, P410, P412 are full width, full height
where
I is the color space (see above) and 3 planes: Y, U and V.
P is a biplanar format, similar to NV12 but 16 bits, with the valid bits in the high bits. There is a Y plane and a UV plane.
0, 2 or 4 is the last digit of subsampling: 4:2:0, 4:2:2, or 4:4:4
10 or 12 is the bits per channel. The bits are in the low bits of a 16 bit channel.
# The ARGB FOURCC
@ -131,3 +163,46 @@ Some are channel order agnostic (e.g. ARGBScale).
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 2 bit alpha has 4 values. Here are the comparable 8 bit alpha values.
0 - 0. 00000000b = 0x00 = 0
1 - 33%. 01010101b = 0x55 = 85
2 - 66%. 10101010b = 0xaa = 170
3 - 100%. 11111111b = 0xff = 255
The 10 bit RGB values range from 0 to 1023.
XR30 is the same as AR30 but with no alpha channel.
# AB64 and AR64
AB64 is similar to ABGR, with 16 bit (2 bytes) per channel. Each channel stores an unsigned short.
In memory R is the lowest and A is the highest.
Each channel has value ranges from 0 to 65535.
AR64 is similar to ARGB.
# 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.
Most NV12 functions allow the destination Y pointer to be NULL.
# YUY2 and UYVY
YUY2 is a packed YUV format with half width, full height.
YUY2 is YUYV in memory
UYVY is UYVY in memory

I420Mirror and ARGBMirror can also be used to rotate by 180 degrees by passing a negative height.
# Cropping - Vertical Flip
When cropping from a subsampled format like NV21, the method of setting the start pointers wont work for odd crop start y on the UV plane.
If the height after cropping will be odd, invert the source - point to the last row, negate the strides, and pass negative height, which
will re-invert the image as the conversion outputs.

Because chromium/src is transitioning to Git (from SVN), we needed to
change the way that the WebRTC standalone checkout works. Instead of
individually syncing subdirectories of Chromium in SVN, we're now
syncing Chromium (and all of its DEPS, as defined by its own DEPS file),
into the `chromium/src` directory.
As such, all Chromium directories which are currently pulled by DEPS are
now replaced with a symlink into the full Chromium checkout.
To avoid disrupting developers, we've chosen to not delete your
directories forcibly, in case you have some work in progress in one of
them :).
ACTION REQUIRED:
Before running `gclient sync|runhooks` again, you must run:
%s%s --force
Which will replace all directories which now must be symlinks, after
prompting with a summary of the work-to-be-done.
