=head1 NAME
make_chlayout_test - produce a multichannel test file with the channels
clearly identified
=head1 SYNOPSIS
tools/make_chlayout_test I<channels> I<out_options>
=head1 DESCRIPTION
This script uses B<ffmpeg> and B<libflite> to produce a file with audio
channels clearly identified by their name. The resulting file can be used to
check that the layout and order of channels is correctly handled by a piece
of software, either a part of B<FFmpeg> or not.
I<channels> is a list of channels or channel layouts, separated by '+'.
I<out_options> is a list of valid ffmpeg outout options, including the
output file.
Note that some output codecs or formats can not handle arbitrary channel
layout.
This script requires a B<ffmpeg> binary, either in the source tree or in the
search path; it must have the flite audio source enabled.
=head1 EXAMPLES
Check that the speakers are correctly plugged:
tools/make_chlayout_test FL+FR -f alsa default
Produce a 5.1 FLAC file:

=head1 NAME
plotframes - Plot video frame sizes using ffprobe and gnuplot
=head1 SYNOPSIS
plotframes [I<options>] [I<input>]
=head1 DESCRIPTION
plotframes reads a multimedia files with ffprobe, and plots the
collected video sizes with gnuplot.
=head1 OPTIONS
=over 4
=item B<--input|-i> I<infile>
Specify multimedia file to read. This is the file passed to the
ffprobe command. If not specified it is the first argument passed to
the script.
=item B<--help|--usage|-h|-?>
Print a brief help message and exit.
=item B<--manpage|-m>
Print the man page.
=item B<--output|-o> I<outfile>
Set the name of the output used by gnuplot. If not specified no output
is created. Must be used in conjunction with the B<terminal> option.
=item B<--stream|--s> I<stream_specifier>
Specify stream. The value must be a string containing a stream
specifier. Default value is "v".
=item B<--terminal|-t> I<terminal>
Set the name of the terminal used by gnuplot. By default it is
"x11". Must be used in conjunction with the B<output> option. Check
the gnuplot manual for the valid values.

/*
* qt-faststart.c, v0.2
* by Mike Melanson (melanson@pcisys.net)
* This file is placed in the public domain. Use the program however you
* see fit.
*
* This utility rearranges a Quicktime file such that the moov atom
* is in front of the data, thus facilitating network streaming.
*
* To compile this program, start from the base directory from which you
* are building FFmpeg and type:
* make tools/qt-faststart
* The qt-faststart program will be built in the tools/ directory. If you
* do not build the program in this manner, correct results are not
* guaranteed, particularly on 64-bit platforms.
* Invoke the program with:
* qt-faststart <infile.mov> <outfile.mov>
*
* Notes: Quicktime files can come in many configurations of top-level
* atoms. This utility stipulates that the very last atom in the file needs
* to be a moov atom. When given such a file, this utility will rearrange
* the top-level atoms by shifting the moov atom from the back of the file
* to the front, and patch the chunk offsets along the way. This utility
* presently only operates on uncompressed moov atoms.
