/*
* This is the source code for our Coverity user model file. The

* code Coverity can't see (out of tree libraries) or doesn't
* sufficiently understand. Better accuracy means both fewer false
* positives and more true defects. Memory leaks in particular.
*
* - A model file can't import any header files. Some built-in primitives are
* available but not wchar_t, NULL etc.
* - Modeling doesn't need full structs and typedefs. Rudimentary structs
* and similar types are sufficient.
* - An uninitialized local variable signifies that the variable could be
* any value.
*
* The model file must be uploaded by an admin in the analysis settings of
* https://scan.coverity.com/projects/54

* above text is based on https://github.com/qemu/qemu/blob/master/scripts/coverity-model.c

=head1 NAME
dvd2concat - create a concat script for a DVD title
=head1 SYNOPSIS
tools/dvd2concat I<path/to/dvd/structure> > I<file.concat>
=head1 DESCRIPTION
This script uses B<lsdvd> to produce concat script for a DVD title.
The resulting script can be used to play the DVD using B<ffplay>, to
transcode it using B<ffmpeg> or any other similar use.
I<path/to/dvd/structure> is the path to the DVD structure hierarchy; it
normally contains a directory named B<VIDEO_TS>. It must not be encrypted
with CSS.
I<file.concat> is the output file. It can be used as an input to ffmpeg.
It will require the B<-safe 0> option.

/*
* To create a simple file for smooth streaming:
* ffmpeg <normal input/transcoding options> -movflags frag_keyframe foo.ismv
* ismindex -n foo foo.ismv
* This step creates foo.ism and foo.ismc that is required by IIS for
* serving it.
*
* With -ismf, it also creates foo.ismf, which maps fragment names to
* start-end offsets in the ismv, for use in your own streaming server.
*
* By adding -path-prefix path/, the produced foo.ism will refer to the
* files foo.ismv as "path/foo.ismv" - the prefix for the generated ismc
* file can be set with the -ismc-prefix option similarly.
*
* To pre-split files for serving as static files by a web server without
* any extra server support, create the ismv file as above, and split it:
* ismindex -split foo.ismv
* This step creates a file Manifest and directories QualityLevel(...),
* that can be read directly by a smooth streaming player.
*
* The -output dir option can be used to request that output files
* (both .ism/.ismc, or Manifest/QualityLevels* when splitting)
* should be written to this directory instead of in the current directory.
* (The directory itself isn't created if it doesn't already exist.)

=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:
tools/make_chlayout_test 5.1 surround.flac

=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.

/* Targeted fuzzer that targets specific codecs depending on two
compile-time flags.
INSTRUCTIONS:
* Get the very fresh clang, e.g. see http://libfuzzer.info#versions
* Get and build libFuzzer:
svn co http://llvm.org/svn/llvm-project/llvm/trunk/lib/Fuzzer
./Fuzzer/build.sh
* build ffmpeg for fuzzing:
FLAGS="-fsanitize=address -fsanitize-coverage=trace-pc-guard,trace-cmp -g" CC="clang $FLAGS" CXX="clang++ $FLAGS" ./configure --disable-x86asm
make clean && make -j
* build the fuzz target.
Choose the value of FFMPEG_CODEC (e.g. AV_CODEC_ID_DVD_SUBTITLE) and
choose one of FUZZ_FFMPEG_VIDEO, FUZZ_FFMPEG_AUDIO, FUZZ_FFMPEG_SUBTITLE.
