WinFF is a GUI for the command line video converter, FFMPEG. It will
convert most any video file that FFmpeg will convert. WinFF does
multiple files in multiple formats at one time. You can for example
convert mpeg's, flv's, and mov's, all into avi's all at once.

lazarus is just a build-time dependency.

NOTE:
If you have a previous ~/.winff directory you might want to
remove it or your presets might not be updated.

WinFF is no longer maintained by the original author. It is currently
maintained by Debian maintainer Paul Gevers and the website winff.org
has been hijacked. See the following post for details:
https://github.com/WinFF/winff/issues/250

I've patched the link for the FFmpeg Windows build website in the
about section to point it to correct website as mentioned on the
FFmpeg website. See the following link for details:
https://ffmpeg.org/download.html#build-windows

The Launchpad link no longer works and I've patched it to point to
the WinFF Debian maintainer's [Paul Gevers] page. I've made sure other
websites link to the https version.

There was also an issue with opening the documentation in Slackware.
The path to the documetation is hardcoded in the source file.
I've patched it to look in the /usr/doc/$PRGNAM-$VERSION directory.

I've patched winff to use xdg-open to use the user's default
PDF viewer.

This build now uses qt5, hence libqtpas is now a dependency. Install
libqtpas before installing lazarus.
