 # Building from source
 **mpegflow** depends only on a recent FFmpeg, **vis** depends on FFmpeg, OpenCV and libpng. The tools are known to work with FFmpeg 3.1 and OpenCV 3.1. You may use [wigwam](http://wigwam.in) to install them to a local directory (no root required):
-```wigwam init && wigwam install opencv ffmpeg``` 
+```wigwam init && wigwam install opencv ffmpeg```

+You will probably end up with a shared build, for static build, please feel free to play with Makefile.
 
 Once the dependencies are visible to g++, run:

You need to keep `avutil-54.dll`, `avformat-56.dll`, `avcodec-56.dll`, `swresample-2.dll` (for **mpegflow**) and `opencv_world310.dll` (for **vis**) in the same directory as the binary. Note that the instructions and the Makefile assume x64 machine architecture.
