Prepare

###macOS

Use Homebrew to install all the dependencies. Use easy_install to install pip

brew install webp
brew install cmake
brew install jsoncpp
sudo easy_install pip

###Linux

sudo apt-get install libwebp-dev
sudo apt-get install cmake
sudo apt-get install libpng-dev
sudo apt-get install zlib1g-dev
sudo apt-get install libjsoncpp-dev
sudo apt-get install python-pip

Compiling and installation:

In apng2webp_dependencies/ execute:

mkdir 'build'
cd build
cmake ..
make
sudo make install

In apng2webp/ execute:

sudo python ./setup.py install

Running:

The default loop is 0(infinity) and bgcolor is 255,255,255,255.

You can also specify a temp dir to save the webp fram and optimized original apng.

apng2webp './input.png' './output.webp'
apng2webp './input.png' [-loop LOOP_COUNT] [-bgcolor BACKGROUND_COLOR] [-tmpdir TEMP_WEBP_DIR] './output.webp'
