ffprobe - ffprobe media prober
ffprobe [
options]
input_url
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
print_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" or
"PROGRAM_STREAM" section.
All the numerical options, if not specified otherwise, accept a string
representing 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
interpreted 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
multiplies 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
corresponding 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.
Some options are applied per-stream, e.g. bitrate or codec. Stream specifiers
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 program ID is also specified. In this case it
is based on the ordering of the streams in the 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 attached pictures, video thumbnails or cover arts. If
additional_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.
-
p:program_id[:additional_stream_specifier]
- Matches streams which are in the program with the id
program_id. If additional_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.
- 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.
These options are shared amongst the ff* tools.
- -L
- 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:
- long
- Print advanced tool options in addition to the basic tool
options.

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.

- Show autodetected sources of the input device. Some devices
may provide 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.
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 values:
- 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 incorrect 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 current 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-YYYYMMDD-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
effect. 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:
- file
- set 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:
- x86
- mmx
- mmxext
- sse
- sse2
- sse2slow
- sse3
- sse3slow
- ssse3
- atom
- sse4.1

- PowerPC
- Specific Processors
- pentium2
- pentium3
- pentium4
- k6
- k62
- athlon
- athlonxp
- k8
-
-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 ffmpeg'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.
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/devices/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 output.
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
-option 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.
-
-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_binary_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 options "-unit -prefix -byte_binary_prefix
-sexagesimal".
-
-of, -print_format
writer_name[=writer_options ]
- Set the output printing format.
writer_name specifies the name of the writer, and
writer_options specifies the options to be passed to the writer.
For example for printing the output in JSON format, specify:
-print_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 affects 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. 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.
- -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_format_entry name
- Like -show_format, but only prints the specified
entry of the container format information, rather than all. This option
may be given more than once, then all specified entries will be shown.
This option is deprecated, use "show_entries" instead.
-
-show_entries section_entries
- Set list of entries to show.
Entries are specified according to the following syntax.
section_entries contains a list of section entries separated by
":". Each section entry is composed by a section name (or unique
name), optionally followed 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 entries 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 retained.
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 specify 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 section
with name "LOG".
- -show_streams
- Show information about each media stream contained in the
input multimedia 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 input multimedia stream.
Each media stream information is printed within a dedicated section with
name "PROGRAM_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
corresponding stream section.
- -count_packets
- Count the number of packets per stream and report it in the
corresponding 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 interval 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 position 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 position if it
is preceded by the "+" character. If the offset specification
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 particular shown element. This option is enabled by default, but you
may need to disable it for specific uses, for example when creating
XSD-compliant XML output.
- -show_program_version
- Show information related to program version.
Version information is printed within a section with name
"PROGRAM_VERSION".
- -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_versions 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 invalid 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.
- -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.
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.
- fail
- The 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 replace.
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 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 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. Default value is 0.
Compact and CSV format.
The "csv" writer is equivalent to "compact", but supports
different defaults.
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" section. 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), carriage return ( \r), a tab (\t), a form feed
( \f), the escaping character ( \) 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
containing a newline ( \n), a carriage return (\r), a double
quote ( "), or SEP are enclosed in double-quotes.
- none
- Perform 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 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 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.
- 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.
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 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_prefix,
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

- 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_format, see TAG:timecode).
