FFPROBE(1) FFPROBE(1)

NAME
ffprobe - ffprobe media prober

SYNOPSIS
ffprobe [options] input_url

DESCRIPTION
ffprobe gathers information from multimedia streams and prints it in human-
and machine-readable fashion.

For example it can be used to check the format of the container used by a
multimedia stream and the format and type of each media stream contained in
it.

If a url is specified in input, ffprobe will try to open and probe the url
content. If the url cannot be opened or recognized as a multimedia file, a
positive exit code is returned.

If no output is specified as output with o ffprobe will write to stdout.

ffprobe may be employed both as a standalone application or in combination
with a textual filter, which may perform more sophisticated processing,
e.g. statistical processing or plotting.

Options are used to list some of the formats supported by ffprobe or for
specifying which information to display, and for setting how ffprobe will
show it.

ffprobe output is designed to be easily parsable by a textual filter, and
consists of one or more sections of a form defined by the selected writer,
which is specified by the output_format option.

Sections may contain other nested sections, and are identified by a name
(which may be shared by other sections), and an unique name. See the output
of sections.

Metadata tags stored in the container or in the streams are recognized and
printed in the corresponding "FORMAT", "STREAM", "STREAM_GROUP_STREAM" or
"PROGRAM_STREAM" section.

OPTIONS
All the numerical options, if not specified otherwise, accept a string rep-
resenting a number as input, which may be followed by one of the SI unit
prefixes, for example: 'K', 'M', or 'G'.

If 'i' is appended to the SI unit prefix, the complete prefix will be in-
terpreted as a unit prefix for binary multiples, which are based on powers
of 1024 instead of powers of 1000. Appending 'B' to the SI unit prefix mul-
tiplies the value by 8. This allows using, for example: 'KB', 'MiB', 'G'
and 'B' as number suffixes.

Options which do not take arguments are boolean options, and set the corre-
sponding value to true. They can be set to false by prefixing the option
name with "no". For example using "-nofoo" will set the boolean option with
name "foo" to false.

Options that take arguments support a special syntax where the argument
given on the command line is interpreted as a path to the file from which
the actual argument value is loaded. To use this feature, add a forward
slash '/' immediately before the option name (after the leading dash). E.g.

ffmpeg -i INPUT -/filter:v filter.script OUTPUT

will load a filtergraph description from the file named filter.script.

Stream specifiers
Some options are applied per-stream, e.g. bitrate or codec. Stream speci-
fiers are used to precisely specify which stream(s) a given option belongs
to.

A stream specifier is a string generally appended to the option name and
separated from it by a colon. E.g. "-codec:a:1 ac3" contains the "a:1"
stream specifier, which matches the second audio stream. Therefore, it
would select the ac3 codec for the second audio stream.

A stream specifier can match several streams, so that the option is applied
to all of them. E.g. the stream specifier in "-b:a 128k" matches all audio
streams.

An empty stream specifier matches all streams. For example, "-codec copy"
or "-codec: copy" would copy all the streams without reencoding.

Possible forms of stream specifiers are:

stream_index
Matches the stream with this index. E.g. "-threads:1 4" would set the
thread count for the second stream to 4. If stream_index is used as an
additional stream specifier (see below), then it selects stream number
stream_index from the matching streams. Stream numbering is based on
the order of the streams as detected by libavformat except when a
stream group specifier or program ID is also specified. In this case it
is based on the ordering of the streams in the group or program.

stream_type[:additional_stream_specifier]
stream_type is one of following: 'v' or 'V' for video, 'a' for audio,
's' for subtitle, 'd' for data, and 't' for attachments. 'v' matches
all video streams, 'V' only matches video streams which are not at-
tached pictures, video thumbnails or cover arts. If addi-
tional_stream_specifier is used, then it matches streams which both
have this type and match the additional_stream_specifier. Otherwise, it
matches all streams of the specified type.

g:group_specifier[:additional_stream_specifier]
Matches streams which are in the group with the specifier group_speci-
fier. if additional_stream_specifier is used, then it matches streams
which both are part of the group and match the additional_stream_speci-
fier. group_specifier may be one of the following:

group_index
Match the stream with this group index.

#group_id or i:group_id
Match the stream with this group id.

p:program_id[:additional_stream_specifier]
Matches streams which are in the program with the id program_id. If ad-
ditional_stream_specifier is used, then it matches streams which both
are part of the program and match the additional_stream_specifier.

#stream_id or i:stream_id
Match the stream by stream id (e.g. PID in MPEG-TS container).

m:key[:value]
Matches streams with the metadata tag key having the specified value.
If value is not given, matches streams that contain the given tag with
any value. The colon character ':' in key or value needs to be back-
slash-escaped.

disp:dispositions[:additional_stream_specifier]
Matches streams with the given disposition(s). dispositions is a list
of one or more dispositions (as printed by the -dispositions option)
joined with '+'.

u Matches streams with usable configuration, the codec must be defined
and the essential information such as video dimension or audio sample
rate must be present.

Note that in ffmpeg, matching by metadata will only work properly for
input files.

Generic options
These options are shared amongst the ff* tools.

-L, -license
Show license.

-h, -?, -help, --help [arg]
Show help. An optional parameter may be specified to print help about a
specific item. If no argument is specified, only basic (non advanced)
tool options are shown.

Possible values of arg are:

longPrint advanced tool options in addition to the basic tool options.

fullPrint complete list of options, including shared and private op-
tions for encoders, decoders, demuxers, muxers, filters, etc.

Note that the term 'codec' is used throughout this documentation as a
shortcut for what is more correctly called a media bitstream format.

-decoders
Show available decoders.

-encoders
Show all available encoders.

-bsfs
Show available bitstream filters.

-protocols
Show available protocols.

-filters
Show available libavfilter filters.

Show available sample formats.

-layouts
Show channel names and standard channel layouts.

-dispositions
Show stream dispositions.

-colors
Show recognized color names.

-sources device[,opt1=val1[,opt2=val2]...]
Show autodetected sources of the input device. Some devices may pro-
vide system-dependent source names that cannot be autodetected. The
returned list cannot be assumed to be always complete.

ffmpeg -sources pulse,server=192.168.0.4

-sinks device[,opt1=val1[,opt2=val2]...]
Show autodetected sinks of the output device. Some devices may provide
system-dependent sink names that cannot be autodetected. The returned
list cannot be assumed to be always complete.

ffmpeg -sinks pulse,server=192.168.0.4

-loglevel [flags+]loglevel | -v [flags+]loglevel
Set logging level and flags used by the library.

The optional flags prefix can consist of the following values:

repeat
Indicates that repeated log output should not be compressed to the
first line and the "Last message repeated n times" line will be
omitted.

level
Indicates that log output should add a "[level]" prefix to each
message line. This can be used as an alternative to log coloring,
e.g. when dumping the log to file.

timeIndicates that log lines should be prefixed with time information.

datetime
Indicates that log lines should be prefixed with date and time in-
formation.

Flags can also be used alone by adding a '+'/'-' prefix to set/reset a
single flag without affecting other flags or changing loglevel. When
setting both flags and loglevel, a '+' separator is expected between
the last flags value and before loglevel.

loglevel is a string or a number containing one of the following val-
ues:

quiet, -8
Show nothing at all; be silent.

panic, 0
Only show fatal errors which could lead the process to crash, such
as an assertion failure. This is not currently used for anything.

fatal, 8
Only show fatal errors. These are errors after which the process
absolutely cannot continue.

error, 16
Show all errors, including ones which can be recovered from.

warning, 24
Show all warnings and errors. Any message related to possibly in-
correct or unexpected events will be shown.

info, 32
Show informative messages during processing. This is in addition to
warnings and errors. This is the default value.

verbose, 40
Same as "info", except more verbose.

debug, 48
Show everything, including debugging information.

trace, 56

For example to enable repeated log output, add the "level" prefix, and
set loglevel to "verbose":

ffmpeg -loglevel repeat+level+verbose -i input output

Another example that enables repeated log output without affecting cur-
rent state of "level" prefix flag or loglevel:

ffmpeg [...] -loglevel +repeat

By default the program logs to stderr. If coloring is supported by the
terminal, colors are used to mark errors and warnings. Log coloring can
be disabled setting the environment variable AV_LOG_FORCE_NOCOLOR, or
can be forced setting the environment variable AV_LOG_FORCE_COLOR.

-report
Dump full command line and log output to a file named "program-YYYYM-
MDD-HHMMSS.log" in the current directory. This file can be useful for
bug reports. It also implies "-loglevel debug".

Setting the environment variable FFREPORT to any value has the same ef-
fect. If the value is a ':'-separated key=value sequence, these options
will affect the report; option values must be escaped if they contain
special characters or the options delimiter ':' (see the ``Quoting and
escaping'' section in the ffmpeg-utils manual).

The following options are recognized:

fileset the file name to use for the report; %p is expanded to the name
of the program, %t is expanded to a timestamp, "%%" is expanded to
a plain "%"

level
set the log verbosity level using a numerical value (see
"-loglevel").

For example, to output a report to a file named ffreport.log using a
log level of 32 (alias for log level "info"):

FFREPORT=file=ffreport.log:level=32 ffmpeg -i input output

Errors in parsing the environment variable are not fatal, and will not
appear in the report.

-hide_banner
Suppress printing banner.

All FFmpeg tools will normally show a copyright notice, build options
and library versions. This option can be used to suppress printing this
information.

-cpuflags flags (global)
Allows setting and clearing cpu flags. This option is intended for
testing. Do not use it unless you know what you're doing.

ffmpeg -cpuflags -sse+mmx ...
ffmpeg -cpuflags mmx ...
ffmpeg -cpuflags 0 ...

Possible flags for this option are:

-cpucount count (global)
Override detection of CPU count. This option is intended for testing.
Do not use it unless you know what you're doing.

ffmpeg -cpucount 2

-max_alloc bytes
Set the maximum size limit for allocating a block on the heap by ffm-
peg's family of malloc functions. Exercise extreme caution when using
this option. Don't use if you do not understand the full consequence of
doing so. Default is INT_MAX.

AVOptions
These options are provided directly by the libavformat, libavdevice and
libavcodec libraries. To see the list of available AVOptions, use the -help
option. They are separated into two categories:

generic
These options can be set for any container, codec or device. Generic
options are listed under AVFormatContext options for containers/devices
and under AVCodecContext options for codecs.

private
These options are specific to the given container, device or codec.
Private options are listed under their corresponding containers/de-
vices/codecs.

For example to write an ID3v2.3 header instead of a default ID3v2.4 to an
MP3 file, use the id3v2_version private option of the MP3 muxer:

ffmpeg -i input.flac -id3v2_version 3 out.mp3

All codec AVOptions are per-stream, and thus a stream specifier should be
attached to them:

ffmpeg -i multichannel.mxf -map 0:v:0 -map 0:a:0 -map 0:a:0 -c:a:0 ac3 -b:a:0 640k -ac:a:1 2 -c:a:1 aac -b:2 128k out.mp4

In the above example, a multichannel audio stream is mapped twice for out-
put. The first instance is encoded with codec ac3 and bitrate 640k. The
second instance is downmixed to 2 channels and encoded with codec aac. A
bitrate of 128k is specified for it using absolute index of the output
stream.

Note: the -nooption syntax cannot be used for boolean AVOptions, use -op-
tion 0/-option 1.

Note: the old undocumented way of specifying per-stream AVOptions by
prepending v/a/s to the options name is now obsolete and will be removed
soon.

Main options
-f format
Force format to use.

-unit
Show the unit of the displayed values.

-prefix
Use SI prefixes for the displayed values. Unless the "-byte_bi-
nary_prefix" option is used all the prefixes are decimal.

-byte_binary_prefix
Force the use of binary prefixes for byte values.

-sexagesimal
Use sexagesimal format HH:MM:SS.MICROSECONDS for time values.

-pretty
Prettify the format of the displayed values, it corresponds to the op-
tions "-unit -prefix -byte_binary_prefix -sexagesimal".

-output_format, -of, -print_format writer_name[=writer_options]
Set the output printing format.

writer_name specifies the name of the writer, and writer_options speci-
fies the options to be passed to the writer.

For example for printing the output in JSON format, specify:

-output_format json

For more details on the available output printing formats, see the
Writers section below.

-sections
Print sections structure and section information, and exit. The output
is not meant to be parsed by a machine.

-select_streams stream_specifier
Select only the streams specified by stream_specifier. This option af-
fects only the options related to streams (e.g. "show_streams",
"show_packets", etc.).

For example to show only audio streams, you can use the command:

ffprobe -show_streams -select_streams a INPUT

To show only video packets belonging to the video stream with index 1:

ffprobe -show_packets -select_streams v:1 INPUT

-show_data
Show payload data, as a hexadecimal and ASCII dump (other formats can
be selected using -data_dump_format). Coupled with -show_packets, it
will dump the packets' data. Coupled with -show_streams, it will dump
the codec extradata.

The dump is printed as the "data" field. It may contain newlines.

-show_data_hash algorithm
Show a hash of payload data, for packets with -show_packets and for
codec extradata with -show_streams.

-data_dump_format format
Select a format used for the data dumps enabled with the -show_data op-
tion. The default is "xxd" which is a hexdump format compatible with
the well-known xxd program. "base64" is also supported.

-show_error
Show information about the error found when trying to probe the input.

The error information is printed within a section with name "ERROR".

-show_format
Show information about the container format of the input multimedia
stream.

All the container format information is printed within a section with
name "FORMAT".

-show_entries section_entries
Set list of entries to show.

Entries are specified according to the following syntax. section_en-
tries contains a list of section entries separated by ":". Each section
entry is composed by a section name (or unique name), optionally fol-
lowed by a list of entries local to that section, separated by ",".

If section name is specified but is followed by no "=", all entries are
printed to output, together with all the contained sections. Otherwise
only the entries specified in the local section entries list are
printed. In particular, if "=" is specified but the list of local en-
tries is empty, then no entries will be shown for that section.

Note that the order of specification of the local section entries is
not honored in the output, and the usual display order will be re-
tained.

The formal syntax is given by:

<LOCAL_SECTION_ENTRIES> ::= <SECTION_ENTRY_NAME>[,<LOCAL_SECTION_ENTRIES>]
<SECTION_ENTRY> ::= <SECTION_NAME>[=[<LOCAL_SECTION_ENTRIES>]]
<SECTION_ENTRIES> ::= <SECTION_ENTRY>[:<SECTION_ENTRIES>]

For example, to show only the index and type of each stream, and the
PTS time, duration time, and stream index of the packets, you can spec-
ify the argument:

packet=pts_time,duration_time,stream_index : stream=index,codec_type

To show all the entries in the section "format", but only the codec
type in the section "stream", specify the argument:

format : stream=codec_type

To show all the tags in the stream and format sections:

stream_tags : format_tags

To show only the "title" tag (if available) in the stream sections:

stream_tags=title

-show_packets
Show information about each packet contained in the input multimedia
stream.

The information for each single packet is printed within a dedicated
section with name "PACKET".

-show_frames
Show information about each frame and subtitle contained in the input
multimedia stream.

The information for each single frame is printed within a dedicated
section with name "FRAME" or "SUBTITLE".

-show_log loglevel
Show logging information from the decoder about each frame according to
the value set in loglevel, (see "-loglevel"). This option requires
"-show_frames".

The information for each log message is printed within a dedicated sec-
tion with name "LOG".

-show_streams
Show information about each media stream contained in the input multi-
media stream.

Each media stream information is printed within a dedicated section
with name "STREAM".

-show_programs
Show information about programs and their streams contained in the in-
put multimedia stream.

Each media stream information is printed within a dedicated section
with name "PROGRAM_STREAM".

-show_stream_groups
Show information about stream groups and their streams contained in the
input multimedia stream.

Each media stream information is printed within a dedicated section
with name "STREAM_GROUP_STREAM".

-show_chapters
Show information about chapters stored in the format.

Each chapter is printed within a dedicated section with name "CHAPTER".

-count_frames
Count the number of frames per stream and report it in the correspond-
ing stream section.

-count_packets
Count the number of packets per stream and report it in the correspond-
ing stream section.

-read_intervals read_intervals
Read only the specified intervals. read_intervals must be a sequence of
interval specifications separated by ",". ffprobe will seek to the in-
terval starting point, and will continue reading from that.

Each interval is specified by two optional parts, separated by "%".

The first part specifies the interval start position. It is interpreted
as an absolute position, or as a relative offset from the current posi-
tion if it is preceded by the "+" character. If this first part is not
specified, no seeking will be performed when reading this interval.

The second part specifies the interval end position. It is interpreted
as an absolute position, or as a relative offset from the current posi-
tion if it is preceded by the "+" character. If the offset specifica-
tion starts with "#", it is interpreted as the number of packets to
read (not including the flushing packets) from the interval start. If
no second part is specified, the program will read until the end of the
input.

Note that seeking is not accurate, thus the actual interval start point
may be different from the specified position. Also, when an interval
duration is specified, the absolute end time will be computed by adding
the duration to the interval start point found by seeking the file,
rather than to the specified start value.

The formal syntax is given by:

<INTERVAL> ::= [<START>|+<START_OFFSET>][%[<END>|+<END_OFFSET>]]
<INTERVALS> ::= <INTERVAL>[,<INTERVALS>]

A few examples follow.

* Seek to time 10, read packets until 20 seconds after the found seek
point, then seek to position "01:30" (1 minute and thirty seconds)
and read packets until position "01:45".

10%+20,01:30%01:45

* Read only 42 packets after seeking to position "01:23":

01:23%+#42

* Read only the first 20 seconds from the start:

%+20

* Read from the start until position "02:30":

%02:30

-show_private_data, -private
Show private data, that is data depending on the format of the particu-
lar shown element. This option is enabled by default, but you may need
to disable it for specific uses, for example when creating XSD-compli-
ant XML output.

-show_program_version
Show information related to program version.

Version information is printed within a section with name "PROGRAM_VER-
SION".

-show_library_versions
Show information related to library versions.

Version information for each library is printed within a section with
name "LIBRARY_VERSION".

-show_versions
Show information related to program and library versions. This is the
equivalent of setting both -show_program_version and -show_library_ver-
sions options.

-show_pixel_formats
Show information about all pixel formats supported by FFmpeg.

Pixel format information for each format is printed within a section
with name "PIXEL_FORMAT".

-show_optional_fields value
Some writers viz. JSON and XML, omit the printing of fields with in-
valid or non-applicable values, while other writers always print them.
This option enables one to control this behaviour. Valid values are
"always"/1, "never"/0 and "auto"/-1. Default is auto.

-analyze_frames
Analyze frames and/or their side data up to the provided read interval,
providing additional information that may be useful at a stream level.
Must be paired with the -show_streams option or it will have no effect.

Currently, the additional fields provided by this option when enabled
are the "closed_captions" and "film_grain" fields.

For example, to analyze the first 20 seconds and populate these fields:

ffprobe -show_streams -analyze_frames -read_intervals "%+20" INPUT

-bitexact
Force bitexact output, useful to produce output which is not dependent
on the specific build.

-i input_url
Read input_url.

-o output_url
Write output to output_url. If not specified, the output is sent to
stdout.

-c:media_specifier codec_name
-codec:media_specifier codec_name
Force a specific decoder implementation for the stream identified by
media_specifier, which can assume the values "a" (audio), "v" (video),
"s" (subtitle), and "d" (data).

WRITERS
A writer defines the output format adopted by ffprobe, and will be used for
printing all the parts of the output.

A writer may accept one or more arguments, which specify the options to
adopt. The options are specified as a list of key=value pairs, separated by
":".

All writers support the following options:

string_validation, sv
Set string validation mode.

The following values are accepted.

failThe writer will fail immediately in case an invalid string (UTF-8)
sequence or code point is found in the input. This is especially
useful to validate input metadata.

ignore
Any validation error will be ignored. This will result in possibly
broken output, especially with the json or xml writer.

replace
The writer will substitute invalid UTF-8 sequences or code points
with the string specified with the string_validation_replacement.

Default value is replace.

string_validation_replacement, svr
Set replacement string to use in case string_validation is set to re-
place.

In case the option is not specified, the writer will assume the empty
string, that is it will remove the invalid sequences from the input
strings.

A description of the currently available writers follows.

default
Default format.

Print each section in the form:

[SECTION]
key1=val1
...
keyN=valN
[/SECTION]

Metadata tags are printed as a line in the corresponding FORMAT, STREAM,
STREAM_GROUP_STREAM or PROGRAM_STREAM section, and are prefixed by the
string "TAG:".

A description of the accepted options follows.

nokey, nk
If set to 1 specify not to print the key of each field. Default value
is 0.

noprint_wrappers, nw
If set to 1 specify not to print the section header and footer. De-
fault value is 0.

compact, csv
Compact and CSV format.

The "csv" writer is equivalent to "compact", but supports different de-
faults.

Each section is printed on a single line. If no option is specified, the
output has the form:

section|key1=val1| ... |keyN=valN

Metadata tags are printed in the corresponding "format" or "stream" sec-
tion. A metadata tag key, if printed, is prefixed by the string "tag:".

The description of the accepted options follows.

item_sep, s
Specify the character to use for separating fields in the output line.
It must be a single printable character, it is "|" by default ("," for
the "csv" writer).

nokey, nk
If set to 1 specify not to print the key of each field. Its default
value is 0 (1 for the "csv" writer).

escape, e
Set the escape mode to use, default to "c" ("csv" for the "csv"
writer).

It can assume one of the following values:

c Perform C-like escaping. Strings containing a newline (\n), car-
riage return (\r), a tab (\t), a form feed (\f), the escaping char-
acter (\) or the item separator character SEP are escaped using
C-like fashioned escaping, so that a newline is converted to the
sequence \n, a carriage return to \r, \ to \\ and the separator SEP
is converted to \SEP.

csv Perform CSV-like escaping, as described in RFC4180. Strings con-
taining a newline (\n), a carriage return (\r), a double quote ("),
or SEP are enclosed in double-quotes.

nonePerform no escaping.

print_section, p
Print the section name at the beginning of each line if the value is 1,
disable it with value set to 0. Default value is 1.

flat
Flat format.

A free-form output where each line contains an explicit key=value, such as
"streams.stream.3.tags.foo=bar". The output is shell escaped, so it can be
directly embedded in sh scripts as long as the separator character is an
alphanumeric character or an underscore (see sep_char option).

The description of the accepted options follows.

sep_char, s
Separator character used to separate the chapter, the section name, IDs
and potential tags in the printed field key.

Default value is ..

hierarchical, h
Specify if the section name specification should be hierarchical. If
set to 1, and if there is more than one section in the current chapter,
the section name will be prefixed by the name of the chapter. A value
of 0 will disable this behavior.

Default value is 1.

ini
INI format output.

Print output in an INI based format.

The following conventions are adopted:

* all key and values are UTF-8

* . is the subgroup separator

* newline, \t, \f, \b and the following characters are escaped

* \ is the escape character

* # is the comment indicator

* = is the key/value separator

* : is not used but usually parsed as key/value separator

This writer accepts options as a list of key=value pairs, separated by :.

The description of the accepted options follows.

Default value is 1.

json
JSON based format.

Each section is printed using JSON notation.

The description of the accepted options follows.

compact, c
If set to 1 enable compact output, that is each section will be printed
on a single line. Default value is 0.

For more information about JSON, see <http://www.json.org/>.

xml
XML based format.

The XML output is described in the XML schema description file ffprobe.xsd
installed in the FFmpeg datadir.

An updated version of the schema can be retrieved at the url
<http://www.ffmpeg.org/schema/ffprobe.xsd>, which redirects to the latest
schema committed into the FFmpeg development source code tree.

Note that the output issued will be compliant to the ffprobe.xsd schema
only when no special global output options (unit, prefix, byte_binary_pre-
fix, sexagesimal etc.) are specified.

The description of the accepted options follows.

fully_qualified, q
If set to 1 specify if the output should be fully qualified. Default
value is 0. This is required for generating an XML file which can be
validated through an XSD file.

xsd_strict, x
If set to 1 perform more checks for ensuring that the output is XSD
compliant. Default value is 0. This option automatically sets
fully_qualified to 1.

For more information about the XML format, see <https://www.w3.org/XML/>.

TIMECODE
ffprobe supports Timecode extraction:

* MPEG1/2 timecode is extracted from the GOP, and is available in the
video stream details (-show_streams, see timecode).

* MOV timecode is extracted from tmcd track, so is available in the tmcd
stream metadata (-show_streams, see TAG:timecode).

* DV, GXF and AVI timecodes are available in format metadata (-show_for-
mat, see TAG:timecode).
