Avanti is powered by Gui4Cli and by its own additional dll's which are all written in C and C++.
Therefore Avanti is small
and relies only on the basic Windows OS resources.
It should run without problems on Windows XP and Vista.
Notes for Windows 7
and 8 users.
Avanti GUI is a free front-end for FFmpeg with the option to insert AviSynth as pre-processor.
It offers user friendly control over all basic and advanced FFmpeg options. A number of template examples are included. No need to be familiar with AviSynth to use the predefined Avanti/AviSynth pre-processor options. Avanti comes as a portable application packed in a zip folder and doesn't require installation. No adware or internet access. (more ...).

We use the Zeranoe FFmpeg builds as reference during Avanti development.
These builds are frequently updated and include all required extra libraries,
FFplay and the full html documentation.
You can download the latest static Win32 build here and copy
and ffplay.exe to the ffmpeg folder at your Avanti install directory. If the latest build fails with the current Avanti version, try an older build from this archive.

The last FFmpeg version we checked out successfully with Avanti 0.9.3 is ...
ffmpeg version N-71959-g9253cc4
 Zeranoe archive date May 7, 2015
Note that this concerns the basic functioning and that there is no guarantee
 that all FFmpeg codecs and options will work as to be expected.

vgtMPEG ...
Avanti supports vgtMPEG which is based on FFmpeg and makes it easy to extract individual titles, chapters and language tags from (unencrypted) ISO, IFO and BDMV structures. You can download a free copy of vgtmpeg here

AviSynth ...
Although optional, we highly recommend to install AviSynth (version 2.5.8 up)
to take advantage of all built-in Avanti/AviSynth options. You can download the latest AviSynth version here
The subtitle option requires you have the "VSFilter.dll" plugin in your AviSynth plugins folder. You can download this plugin here
7-ZIP ...
The Avanti package and some of the FFmpeg builds are packed with 7-Zip.
If you have problems with unpacking, you can download 7-Zip here
Support ...
The past seven years the developer of Avanti maintained a support thread at
the forums. It might be of help to read through the questions
and answers there in case the included Avanti chm help does not provide all
the answers.
