=head1 NAME
ffcat - the Fast & Furious Lossless Media Concatenation Tool
=head1 SYNOPSIS
ffcat [<options>] <input-files> [<output-file>]
Options are:
-o <output> Provide output filename upfront instead of at the end
-v(erbose) Show what is going on
-x(amine) Immediately play the resulting video in mpv or mplayer
-q(uiet) Turn off audio when playing resulting video
-s(ilent) Produce output video without audio
-a(udio) Produce output audio without video
-b(oxing) Plan B: prefer MP4Box over ffmpeg
-Q(uiet) Do not produce screen output
=head1 DESCRIPTION
ffcat concatenates video or sound files into a single output file without
the need of re-encoding. It can use both ffmpeg and the GPAC package.
Plan B: When ffmpeg messes up the audio sync of the resulting video or when
it cannot handle some broken mp4/mov/3gp files, you can still try out GPAC!
