external libraries
|
||||
==================
|
||||
|
||||
FFmpeg can be combined with a number of external libraries, which sometimes
|
||||
affect the licensing of binaries resulting from the combination.
|
||||
|
||||
### Compatible libraries

|
||||
--------------------
|
||||
|
||||
The following libraries are under GPL:
|
||||
- frei0r
|
||||
- libcdio
|
||||
- librubberband
|
||||
- libvidstab
|
||||
- libx264

passing `--enable-gpl` to configure.
|

passing --enable-gpl to configure.
|
||||
|

The OpenCORE and VisualOn libraries are under the Apache License 2.0. That
|
||||
license is incompatible with the LGPL v2.1 and the GPL v2, but not with
|
||||
version 3 of those licenses. So to combine these libraries with FFmpeg, the
|
||||
license version needs to be upgraded by passing `--enable-version3` to configure.

### Incompatible libraries
|

incompatible libraries
|
||||
----------------------
|
||||
|
||||
There are certain libraries you can combine with FFmpeg whose licenses are not
|
||||
compatible with the GPL and/or the LGPL. If you wish to enable these
|
||||
libraries, even in circumstances that their license may be incompatible, pass
|
||||
`--enable-nonfree` to configure. But note that if you enable any of these
|
||||
libraries the resulting binary will be under a complex license mix that is
|
||||
more restrictive than the LGPL and that may result in additional obligations.
|
||||
It is possible that these restrictions cause the resulting binary to be
|
||||
unredistributable.
|
||||
|
||||
The Fraunhofer FDK AAC and OpenSSL libraries are under licenses which are
|
||||
incompatible with the GPLv2 and v3. To the best of our knowledge, they are
|
||||
compatible with the LGPL.
|
||||
|
||||
The FAAC library is incompatible with all versions of GPL and LGPL.
|
||||
|
||||
The NVENC library, while its header file is licensed under the compatible MIT
|
||||
license, requires a proprietary binary blob at run time, and is deemed to be
|
||||
incompatible with the GPL. We are not certain if it is compatible with the
|
||||
LGPL, but we require `--enable-nonfree` even with LGPL configurations in case
|
||||
it is not.
|
||||
The Fraunhofer AAC library, FAAC and aacplus are under licenses which
|
||||
are incompatible with the GPLv2 and v3. We do not know for certain if their
|
||||
licenses are compatible with the LGPL.
|
||||
If you wish to enable these libraries, pass --enable-nonfree to configure.
|
||||
But note that if you enable any of these libraries the resulting binary will
|
||||
be under a complex license mix that is more restrictive than the LGPL and that
|
||||
may result in additional obligations. It is possible that these
|
||||
restrictions cause the resulting binary to be unredistributeable.

|
||||
Add FF_PROFILE_H264_MULTIVIEW_HIGH and FF_PROFILE_H264_STEREO_HIGH.
|
||||
|
||||
2016-06-30 - c1c7e0ab - lavf 57.41.100 - avformat.h
|
||||
Moved codecpar field from AVStream to the end of the struct, so that
|
||||
the following private fields are in the same location as in FFmpeg 3.0 (lavf 57.25.100).
|
||||
|
||||
2016-06-30 - 042fb69d - lavu 55.28.100 - frame.h
|
||||
Moved hw_frames_ctx field from AVFrame to the end of the struct, so that
|
||||
the following private fields are in the same location as in FFmpeg 3.0 (lavu 55.17.103).
|
||||
|
||||
2016-06-29 - 1a751455 - lavfi 6.47.100 - avfilter.h
|
||||
Fix accidental ABI breakage in AVFilterContext.
|
||||
ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
|
||||
|
||||
Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
|
||||
compatible with lavfi>=6.47.100. Potentially also affects other users of
|
||||
libavfilter if they are using one of the affected fields.
|
||||
|
||||
-------- 8< --------- FFmpeg 3.1 was cut here -------- 8< ---------
|

|
||||
|
||||
2016-04-02 - e8a9b64 - lavu 55.20.100 - base64.h
|
||||
Add AV_BASE64_DECODE_SIZE(x) macro.
|
||||
|
||||
2016-xx-xx - lavc 57.33.100 / 57.14.0 - avcodec.h
|
||||
f9b1cf1 / 998e1b8 - Add AVCodecParameters and its related API.
|
||||
e6053b3 / a806834 - Add av_get_audio_frame_duration2().
|
||||
|
||||
2016-03-11 - 6d8ab35 - lavf/lavc 57.28.101
|
||||
Add requirement to bitstream filtering API that returned packets with
|
||||
size == 0 and side_data_elems == 0 are to be skipped by the caller.
|
||||
|
||||
2016-03-04 - 9362973 - lavf 57.28.100
|
||||
Add protocol blacklisting API
|
||||
|
||||
2016-02-28 - 4dd4d53 - lavc 57.27.101
|
||||
Validate AVFrame returned by get_buffer2 to have required
|
||||
planes not NULL and unused planes set to NULL as crashes
|
||||
and buffer overflow are possible with certain streams if
|
||||
that is not the case.
|
||||
|
||||
2016-02-26 - 30e7685 - lavc 57.27.100 - avcodec.h
|
||||
"flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
|
||||
the reset of the ASS ReadOrder field on flush. This affects the content of
|
||||
AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
|
||||
previous entry).
|
||||
|
||||
2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
|
||||
Add a "sub_text_format" subtitles decoding option allowing the values "ass"
|
||||
(recommended) and "ass_with_timings" (not recommended, deprecated, default).
|
||||
The default value for this option will change to "ass" at the next major
|
||||
libavcodec version bump.
|
||||
|
||||
The current default is "ass_with_timings" for compatibility. This means that
|
||||
all subtitles text decoders currently still output ASS with timings printed
|
||||
as strings in the AVSubtitles.rects[N]->ass fields.
|
||||
|
||||
Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
|
||||
timing is limited to a 1/100 time base, so this is relevant for any subtitles
|
||||
format needing a bigger one), ease timing adjustments, and prevents the need
|
||||
of removing the timing from the decoded string yourself. This form is also
|
||||
known as "the Matroska form". The timing information (start time, duration)
|
||||
can be found in the AVSubtitles fields.
|
||||
|
||||
2016-02-24 - 7e49cdd / 7b3214d0 - lavc 57.25.100 / 57.13.0 - avcodec.h
|
||||
Add AVCodecContext.hw_frames_ctx.
|
||||
|
||||
2016-02-24 - 1042402 / b3dd30d - lavfi 6.36.100 / 6.2.0 - avfilter.h
|
||||
avfilter.h - Add AVFilterLink.hw_frames_ctx.
|
||||
buffersrc.h - Add AVBufferSrcParameters and functions for handling it.
|

||||
Add AV_PKT_DATA_MPEGTS_STREAM_ID for exporting the MPEGTS stream ID.
|

|

@item @code{inpoint @var{timestamp}}
|
||||
In point of the file. When the demuxer opens the file it instantly seeks to the

specified timestamp. Seeking is done so that all streams can be presented
|
||||
successfully at In point.
|
||||
|
||||
This directive works best with intra frame codecs, because for non-intra frame
|
||||
ones you will usually get extra packets before the actual In point and the
|
||||
decoded content will most likely contain frames before In point too.
|
||||
|
||||
For each file, packets before the file In point will have timestamps less than
|
||||
the calculated start timestamp of the file (negative in case of the first
|
||||
file), and the duration of the files (if not specified by the @code{duration}

@item @code{outpoint @var{timestamp}}
|

Out point of the file. When the demuxer reaches the specified decoding

timestamp in any of the streams, it handles it as an end of file condition and
|
||||
skips the current and all the remaining packets from all streams.
|
||||
|
||||
Out point is exclusive, which means that the demuxer will not output packets
|
||||
with a decoding timestamp greater or equal to Out point.
|
||||
|
||||
This directive works best with intra frame codecs and formats where all streams
|
||||
are tightly interleaved. For non-intra frame codecs you will usually get
|
||||
additional packets with presentation timestamp after Out point therefore the
|
||||
decoded content will most likely contain frames after Out point too. If your

streams are not tightly interleaved you may not get all the packets from all

Advanced Audio Coding (AAC) encoder.
|

|
||||
This encoder is the default AAC encoder, natively implemented into FFmpeg. Its
|
||||
quality is on par or better than libfdk_aac at the default bitrate of 128kbps.
|
||||
This encoder also implements more options, profiles and samplerates than
|
||||
other encoders (with only the AAC-HE profile pending to be implemented) so this
|
||||
encoder has become the default and is the recommended choice.
|
||||
This encoder is an experimental FFmpeg-native AAC encoder. Currently only the
|
||||
low complexity (AAC-LC) profile is supported. To use this encoder, you must set
|
||||
@option{strict} option to @samp{experimental} or lower.
|
||||
|
||||
As this encoder is experimental, unexpected behavior may exist from time to
|
||||
time. For a more stable AAC encoder, see @ref{libvo-aacenc}. However, be warned
|
||||
that it has a worse quality reported by some users.

FAAC-inspired method.
|
||||
|
||||
This method is a simplified reimplementation of the method used in FAAC, which
|
||||
sets thresholds proportional to the band energies, and then decreases all the
|
||||
thresholds with quantizer steps to find the appropriate quantization with
|
||||
distortion below threshold band by band.
|
||||
|
||||
The quality of this method is comparable to the two loop searching method
|
||||
described below, but somewhat a little better and slower.
|
||||
|
||||
@item anmr
|
||||
Average noise to mask ratio (ANMR) trellis-based solution.
|
||||
|
||||
This has a theoretic best quality out of all the coding methods, but at the
|
||||
cost of the slowest speed.
|
||||
|
||||
@item twoloop
|
||||
Two loop searching (TLS) method.
|
||||
|
||||
This method first sets quantizers depending on band thresholds and then tries
|
||||
to find an optimal combination by adding or subtracting a specific value from
|
||||
all quantizers and adjusting some individual quantizer a little.
|
||||
Will tune itself based on whether aac_is/aac_ms/aac_pns are enabled.
|
||||
This is the default choice for a coder.
|
||||
|
||||
@item anmr
|
||||
Average noise to mask ratio (ANMR) trellis-based solution.
|
||||
|
||||
This is an experimental coder which currently produces a lower quality, is more
|
||||
unstable and is slower than the default twoloop coder but has potential.
|
||||
Currently has no support for the @option{aac_is} or @option{aac_pns} options.
|
||||
Not currently recommended.
|
||||
This method produces similar quality with the FAAC method and is the default.
|
||||

Constant quantizer method.
|
||||
|
||||
This method sets a constant quantizer for all bands. This is the fastest of all

|
||||
@item aac_ms
|
||||
Sets mid/side coding mode. The default value of auto will automatically use
|
||||
M/S with bands which will benefit from such coding. Can be forced for all bands
|
||||
using the value "enable", which is mainly useful for debugging or disabled using
|
||||
"disable".
|
||||
|
||||
@item aac_is
|
||||
Sets intensity stereo coding tool usage. By default, it's enabled and will
|
||||
automatically toggle IS for similar pairs of stereo bands if it's benefitial.
|
||||
Can be disabled for debugging by setting the value to "disable".
|
||||
|
||||
@item aac_pns
|
||||
Uses perceptual noise substitution to replace low entropy high frequency bands
|
||||
with imperceivable white noise during the decoding process. By default, it's
|
||||
enabled, but can be disabled for debugging purposes by using "disable".
|
||||
|
||||
@item aac_tns
|
||||
Enables the use of a multitap FIR filter which spans through the high frequency
|
||||
bands to hide quantization noise during the encoding process and is reverted
|
||||
by the decoder. As well as decreasing unpleasant artifacts in the high range
|
||||
this also reduces the entropy in the high bands and allows for more bits to
|
||||
be used by the mid-low bands. By default it's enabled but can be disabled for
|
||||
debugging by setting the option to "disable".
|
||||
|
||||
@item aac_ltp
|
||||
Enables the use of the long term prediction extension which increases coding
|
||||
efficiency in very low bandwidth situations such as encoding of voice or
|
||||
solo piano music by extending constant harmonic peaks in bands throughout
|
||||
frames. This option is implied by profile:a aac_low and is incompatible with
|
||||
aac_pred. Use in conjunction with @option{-ar} to decrease the samplerate.
|
||||
|
||||
@item aac_pred
|
||||
Enables the use of a more traditional style of prediction where the spectral
|
||||
coefficients transmitted are replaced by the difference of the current
|
||||
coefficients minus the previous "predicted" coefficients. In theory and sometimes
|
||||
in practice this can improve quality for low to mid bitrate audio.
|
||||
This option implies the aac_main profile and is incompatible with aac_ltp.
|
||||
|
||||
@item profile
|
||||
Sets the encoding profile, possible values:
|
||||
|
||||
@table @samp
|
||||
@item aac_low
|
||||
The default, AAC "Low-complexity" profile. Is the most compatible and produces
|
||||
decent quality.
|
||||
|
||||
@item mpeg2_aac_low
|
||||
Equivalent to -profile:a aac_low -aac_pns 0. PNS was introduced with the MPEG4
|
||||
specifications.
|
||||
|
||||
@item aac_ltp
|
||||
Long term prediction profile, is enabled by and will enable the aac_ltp option.
|
||||
Introduced in MPEG4.
|
||||
|
||||
@item aac_main
|
||||

encoder use CAVLC instead of CABAC.
|
||||
|
||||
@end itemize
|
||||
|
||||
@section vc2
|
||||
|
||||
SMPTE VC-2 (previously BBC Dirac Pro). This codec was primarily aimed at
|
||||
professional broadcasting but since it supports yuv420, yuv422 and yuv444 at
|
||||
8 (limited range or full range), 10 or 12 bits, this makes it suitable for
|
||||
other tasks which require low overhead and low compression (like screen
|
||||
recording).
|
||||
|
||||
@subsection Options
|
||||
|
||||
@table @option
|
||||
|
||||
@item b
|
||||
Sets target video bitrate. Usually that's around 1:6 of the uncompressed
|
||||
video bitrate (e.g. for 1920x1080 50fps yuv422p10 that's around 400Mbps). Higher
|
||||
values (close to the uncompressed bitrate) turn on lossless compression mode.
|
||||
|
||||
@item field_order
|
||||
Enables field coding when set (e.g. to tt - top field first) for interlaced
|
||||
inputs. Should increase compression with interlaced content as it splits the
|
||||
fields and encodes each separately.
|
||||
|
||||
@item wavelet_depth
|
||||
Sets the total amount of wavelet transforms to apply, between 1 and 5 (default).
|
||||
Lower values reduce compression and quality. Less capable decoders may not be
|
||||
able to handle values of @option{wavelet_depth} over 3.
|
||||
|
||||
@item wavelet_type
|
||||
Sets the transform type. Currently only @var{5_3} (LeGall) and @var{9_7}
|
||||
(Deslauriers-Dubuc)
|
||||
are implemented, with 9_7 being the one with better compression and thus
|
||||
is the default.
|
||||
|
||||
@item slice_width
|
||||
@item slice_height
|
||||
Sets the slice size for each slice. Larger values result in better compression.
|
||||
For compatibility with other more limited decoders use @option{slice_width} of
|
||||
32 and @option{slice_height} of 8.
|
||||
|
||||
@item tolerance
|
||||
Sets the undershoot tolerance of the rate control system in percent. This is
|
||||
to prevent an expensive search from being run.
|
||||
|
||||
@item qm
|
||||
Sets the quantization matrix preset to use by default or when @option{wavelet_depth}
|
||||
is set to 5
|
||||
@itemize @minus
|
||||
@item
|
||||
@var{default}
|
||||
Uses the default quantization matrix from the specifications, extended with
|
||||
values for the fifth level. This provides a good balance between keeping detail
|
||||
and omitting artifacts.
|
||||
|
||||
@item
|
||||
@var{flat}
|
||||
Use a completely zeroed out quantization matrix. This increases PSNR but might
|
||||
reduce perception. Use in bogus benchmarks.
|
||||
|
||||
@item
|
||||
@var{color}
|
||||
Reduces detail but attempts to preserve color at extremely low bitrates.

@section How do I make @command{pkg-config} find my libraries?
|
||||
|
||||
Somewhere along with your libraries, there is a @file{.pc} file (or several)
|
||||
in a @file{pkgconfig} directory. You need to set environment variables to
|
||||
point @command{pkg-config} to these files.
|
||||
|
||||
If you need to @emph{add} directories to @command{pkg-config}'s search list
|
||||
(typical use case: library installed separately), add it to
|
||||
@code{$PKG_CONFIG_PATH}:
|
||||
|
||||
@example
|
||||
export PKG_CONFIG_PATH=/opt/x264/lib/pkgconfig:/opt/opus/lib/pkgconfig
|
||||
@end example
|
||||
|
||||
If you need to @emph{replace} @command{pkg-config}'s search list
|
||||
(typical use case: cross-compiling), set it in
|
||||
@code{$PKG_CONFIG_LIBDIR}:
|
||||
|
||||
@example
|
||||
export PKG_CONFIG_LIBDIR=/home/me/cross/usr/lib/pkgconfig:/home/me/cross/usr/local/lib/pkgconfig
|
||||
@end example
|
||||
|
||||
If you need to know the library's internal dependencies (typical use: static
|
||||
linking), add the @code{--static} option to @command{pkg-config}:
|
||||
|
||||
@example
|
||||
./configure --pkg-config-flags=--static
|
||||
@end example
|
||||
|
||||
@section How do I use @command{pkg-config} when cross-compiling?
|
||||
|
||||
The best way is to install @command{pkg-config} in your cross-compilation
|
||||
environment. It will automatically use the cross-compilation libraries.
|
||||
|
||||
You can also use @command{pkg-config} from the host environment by
|
||||
specifying explicitly @code{--pkg-config=pkg-config} to @command{configure}.
|
||||
In that case, you must point @command{pkg-config} to the correct directories
|
||||
using the @code{PKG_CONFIG_LIBDIR}, as explained in the previous entry.
|
||||
|
||||
As an intermediate solution, you can place in your cross-compilation
|
||||
environment a script that calls the host @command{pkg-config} with
|
||||
@code{PKG_CONFIG_LIBDIR} set. That script can look like that:
|
||||
|
||||
@example
|
||||
#!/bin/sh
|
||||
PKG_CONFIG_LIBDIR=/path/to/cross/lib/pkgconfig
|
||||
export PKG_CONFIG_LIBDIR
|
||||
exec /usr/bin/pkg-config "$@@"

|

@section I have a stretched video, why does scaling does not fix it?
|
||||
|
||||
A lot of video codecs and formats can store the @emph{aspect ratio} of the
|
||||
video: this is the ratio between the width and the height of either the full
|
||||
image (DAR, display aspect ratio) or individual pixels (SAR, sample aspect
|
||||
ratio). For example, EGA screens at resolution 640×350 had 4:3 DAR and 35:48
|
||||
SAR.
|
||||
|
||||
Most still image processing work with square pixels, i.e. 1:1 SAR, but a lot
|
||||
of video standards, especially from the analogic-numeric transition era, use
|
||||
non-square pixels.
|
||||
|
||||
Most processing filters in FFmpeg handle the aspect ratio to avoid
|
||||
stretching the image: cropping adjusts the DAR to keep the SAR constant,
|
||||
scaling adjusts the SAR to keep the DAR constant.
|
||||
|
||||
If you want to stretch, or “unstretch”, the image, you need to override the
|
||||
information with the
|
||||
@url{https://ffmpeg.org/ffmpeg-filters.html#setdar_002c-setsar, @code{setdar or setsar filters}}.
|
||||
|
||||
Do not forget to examine carefully the original video to check whether the
|
||||
stretching comes from the image or from the aspect ratio information.
|
||||
|
||||
For example, to fix a badly encoded EGA capture, use the following commands,
|
||||
either the first one to upscale to square pixels or the second one to set
|
||||
the correct aspect ratio or the third one to avoid transcoding (may not work
|
||||
depending on the format / codec / player / phase of the moon):
|
||||
|
||||
@example
|
||||
ffmpeg -i ega_screen.nut -vf scale=640:480,setsar=1 ega_screen_scaled.nut
|
||||
ffmpeg -i ega_screen.nut -vf setdar=4/3 ega_screen_anamorphic.nut

For streaming at very low bitrates, use a low frame rate
|
||||
and a small GOP size. This is especially true for RealVideo where
|
||||
the Linux player does not seem to be very fast, so it can miss
|
||||
frames. An example is:
|
||||
|
||||
@example
|
||||
ffmpeg -g 3 -r 3 -t 10 -b:v 50k -s qcif -f rv10 /tmp/b.rm

The parameter 'q' which is displayed while encoding is the current
|
||||
quantizer. The value 1 indicates that a very good quality could
|
||||
be achieved. The value 31 indicates the worst quality. If q=31 appears
|
||||
too often, it means that the encoder cannot compress enough to meet
|
||||
your bitrate. You must either increase the bitrate, decrease the
|
||||
frame rate or decrease the frame size.
|
||||
|
||||
@item
|
||||
If your computer is not fast enough, you can speed up the
|
||||
compression at the expense of the compression ratio. You can use
|
||||
'-me zero' to speed up motion estimation, and '-g 0' to disable
|
||||
motion estimation completely (you have only I-frames, which means it
|
||||
is about as good as JPEG compression).

@item

||||
To have very low audio bitrates, reduce the sampling frequency
|
||||
(down to 22050 Hz for MPEG audio, 22050 or 11025 for AC-3).
|
||||
|
||||
@item

To have a constant quality (but a variable bitrate), use the option

This option is used to benchmark all available OpenCL devices and print the

@code{--enable-opencl}.
|
||||
|
||||
When FFmpeg is configured with @code{--enable-opencl}, the options for the
|
||||
global OpenCL context are set via @option{-opencl_options}. See the
|
||||
"OpenCL Options" section in the ffmpeg-utils manual for the complete list of
|
||||
supported options. Amongst others, these options include the ability to select
|
||||
a specific platform and device to run the OpenCL code on. By default, FFmpeg
|
||||
will run on the first device of the first platform. While the options for the
|
||||
global OpenCL context provide flexibility to the user in selecting the OpenCL
|
||||
device of their choice, most users would probably want to select the fastest
|
||||
OpenCL device for their system.
|
||||
|
||||
This option assists the selection of the most efficient configuration by
|
||||
identifying the appropriate device for the user's system. The built-in
|
||||
benchmark is run on all the OpenCL devices and the performance is measured for
|
||||
each device. The devices in the results list are sorted based on their
|
||||
performance with the fastest device listed first. The user can subsequently
|
||||
invoke @command{ffmpeg} using the device deemed most appropriate via
|
||||
@option{-opencl_options} to obtain the best performance for the OpenCL
|
||||
accelerated code.
|
||||
|
||||
Typical usage to use the fastest OpenCL device involve the following steps.

||||
Run the command:
|

@example
|

ffmpeg -opencl_bench

FFmpeg can use Intel QuickSync Video (QSV) for accelerated encoding and decoding

dispatcher, which loads the actual decoding libraries.

The dispatcher is open source and can be downloaded from

with the @code{--enable-libmfx} option and @code{pkg-config} needs to be able to

@section decklink
|

|

The decklink input device provides capture capabilities for Blackmagic
|
||||
DeckLink devices.
|
||||
|
||||
To enable this input device, you need the Blackmagic DeckLink SDK and you
|
||||
need to configure with the appropriate @code{--extra-cflags}
|
||||
and @code{--extra-ldflags}.
|
||||
On Windows, you need to run the IDL files through @command{widl}.
|
||||
|
||||
DeckLink is very picky about the formats it supports. Pixel format is
|
||||
uyvy422 or v210, framerate and video size must be determined for your device with
|
||||
@command{-list_formats 1}. Audio sample rate is always 48 kHz and the number
|
||||
of channels can be 2, 8 or 16. Note that all audio channels are bundled in one single
|
||||
audio track.

|
||||
|
||||
@item teletext_lines
|
||||
If set to nonzero, an additional teletext stream will be captured from the
|
||||
vertical ancillary data. This option is a bitmask of the VBI lines checked,
|
||||
specifically lines 6 to 22, and lines 318 to 335. Line 6 is the LSB in the mask.
|
||||
Selected lines which do not contain teletext information will be ignored. You
|
||||
can use the special @option{all} constant to select all possible lines, or
|
||||
@option{standard} to skip lines 6, 318 and 319, which are not compatible with all
|
||||
receivers. Capturing teletext only works for SD PAL sources in 8 bit mode.

To use this option, ffmpeg needs to be compiled with @code{--enable-libzvbi}.
