ffmpeg.org official website
GENERATE THE WEBSITE
--------------------
`lessc` and `clean-css` are required to generate CSS of the website.[1]
Type `make` to generate the website.
Type `make clean` to remove the generated files.
GENERATE THE DOCUMENTATION
--------------------------
/!\ None of the generated versions of the website contain the documentation.
To generate the documentation pages, just `./generate-doc.sh <ffmpeg-src>`.
In case of a major CSS update, please also update the `style.min.css` file in
the main FFmpeg repo
  $ cp htdocs/css/{bootstrap.min.css,style.min.css} /path/to/ffmpeg/doc/
WEBSITE DEVELOPERS INSTRUCTIONS
-------------------------------
npm, lessc and bower are required to generate the website in development.[2]
Type `make DEV=1` to generate the website for development.
Type `make clean DEV=1` to remove the generated files.
In development mode, the external dependencies are downloaded through bower.
Thanks to lessc, you can edit the *.less sources and see the changes on your
browser without having to reload it.
-----
[1] lessc is available on the packages of some distributions.
Otherwise, follow the instructions in [2].
lessc depends on lots of stuff including npm, so if you wish to use a lighter version,
you might want to check out the C++ version: https://www.vanderkroef.net/clessc.html
