The documentation for Bento4 consists of pages hosted on this site, documents stored as files in the source distribution and SDKs, as well as embedded documentation in the source code header files.
MPEG DASH Packager
The MPEG DASH Overview page is the starting point for information on MPEG DASH packaging.
For a more advanced, detailed set of options, you can also directly consult the documentation for the

Library API Documentation
Some of the API documentation is produced from the source code comments using Doxygen. The doxygen output is available as a windows CHM file in Bento4.chm, and a set of HTML pages zipped together in Bento4-HTML.zip (to start, open the file named index.html with an HTML browser)
