### Autotools
|
||||
Depending on the platform, some additional tools are required for compiling uvg266 with autotools.
|
||||
For Ubuntu, the required packages are `automake autoconf libtool m4 build-essential yasm`. Yasm is
|
||||
optional, but some of the optimization will not be compiled in if it's missing.
|
||||
### CMake
|
||||
Depending on the platform, some additional tools are required for compiling uvg266 with CMake.
|
||||
For Ubuntu, the required packages are `automake autoconf build-essential`.
|
||||
|
||||
Run the following commands to compile and install uvg266.
|
||||
|
||||
./autogen.sh
|
||||
./configure
|
||||
cd build
|
||||
cmake ..

make

See `./configure --help` for more options.

Visual Studio natively supports opening the `CMakeLists.txt` of the CMake build package has been installed.
|

Otherwise CMake-CLI can be used to generate the Visual Studio project files.

|

### Autotools on MinGW
|
||||
It is recommended to use Clang instead of GCC in MinGW environments. GCC also works, but AVX2 optimizations will be disabled because of a known GCC issue from 2012, so performance will suffer badly. Instead of `./configure`, run
|
||||
### Docker
|
||||
This project includes a [Dockerfile](./Dockerfile), which enables building for Docker.
|
||||
Build using Docker: `docker build -t uvg266 .`
|
||||
Example usage: `docker run -i -a STDIN -a STDOUT uvg266 -i - --input-res=320x240 -o - < testfile_320x240.yuv > out.266`
