This programs motivation was sometimes when downloading videos they are not encoded properly. Thus some video players integrated in apps like Signal cannot play these videos, and you have to download and open them in an external video player. By feeding the video through FFmpeg, it gets reencoded. This fixes the problem most of the time.
This program is a simple UI to not have to deal with commandline arguments for FFmpeg manually. It is created using PureBasic to have a very minimal executable size. FFmpeg is downloaded at runtime.
Please be aware that this program might be flagged by Anti-Malware Software due to it running an external program (FFmpeg). A VirusTotal scan for the current version can be seen here. The source code can be found here.
Updated compilation flags and changed update method to (hopefully) create less false-positives by anti-malware software
