# uavs3d
 uavs3d is an opensource and cross-platform avs3 decoder, supports AVS3-P2 baseline profile. <br>
 features:
 1) AVS3-P2 baseline profile.
 2) supports to compile for Android/IOS/Windows/Linux/MacOS systems.
 3) optimized for ARMv7/ARMv8/SSE4/AVX2 chips.
 4) 10bit decoding on all supported platforms.
 5) The uavs3 codec has supported x86 and arm platforms, and has been tested and verified on the Kunpeng processor. 
 6) The ARM platform recommends the Kunpeng processor.

# compile
  The default configuration only support 8bit decoding. <br>
  To support 10bit streams decoding: cmake -DCOMPILE_10BIT=1

## windows
Prerequisites:
  Visual Studio 2017

build:
  1. ./version.bat (to generate version.h)
  2. solution file: build/x86_windows/uavs3d.sln 
  
  To support 10bit streams decoding, edit source/decore/com_def.h : #define COMPILE_10BIT 1

## linux/mac
Prerequisites:
  1. gawk (http://www.gnu.org/software/gawk/)
  2. CMake (https://cmake.org) version 3.1 or higher
  
Build:
  1. mkdir build/linux
  2. cd build/linux && cmake -DCOMPILE_10BIT=0 ../..
  3. make && make install

  To support 10bit streams decoding: cmake -DCOMPILE_10BIT=1
  to build shared library, set BUILD_SHARED_LIBS=1 please.

## ios
Prerequisites:
  XCode

Build:
  1. ./version.sh (generate the version.h) 
  2. xcode solution file: build/ios/uavs3d.xcodeproj

  To support 10bit streams decoding:
  Find Xcode -> PROJECT -> Build Settings -> Preprocessor Macros, add COMPILE_10BIT=1

## android
Prerequisites:
  Android NDK (https://developer.android.google.cn/ndk/downloads/).

Build ndk library or executable file: 
  1. ./version.sh (generate the version.h)
  2. cd build/android/ndk/jni
  3. $NDK_PATH/ndk-build  

  To support 10bit streams decoding: edit build/android/ndk/jni/uavs3d_main.mk:
  
  LOCAL_CFLAGS	+= -DCOMPILE_10BIT=1

# Run tests
## window/linux/mac/android
sample: ./uavs3d -i input.avs3 -o output.yuv -t 8 -l 2 -s 1

Arguments: <br>

| short name | long name | introduction |
|:-----------:|----------|-------------|
| -h | --help     | Print this help     |
| -v | --version  | Version information |
| -i | --input    | Input file          |
| -o | --output   | Output file         |
| -l | --loglevel | Log level: <br> 0: no message; 1: seq level; 2: frame level (default) |
| -t | --threads  | Number of frame-level threads |
| -f | --frames   | Total frames to decode        |
| -s | --check_md5| Enable to check md5 or not    |

## ios
  Edit build/ios/uavs3d/main.m to configure decoding options.
