10
12 ffprobe gathers information from multimedia streams and prints it in
13 human- and machine-readable fashion.
14 For example it can be used to check the format of the container used by
16 a multimedia stream and the format and type of each media stream
17 contained in it.
18 If a url is specified in input, ffprobe will try to open and probe the
20 url content. If the url cannot be opened or recognized as a multimedia
21 file, a positive exit code is returned.
22 ffprobe may be employed both as a standalone application or in
24 combination with a textual filter, which may perform more sophisticated
25 processing, e.g. statistical processing or plotting.
26 Options are used to list some of the formats supported by ffprobe or
28 for specifying which information to display, and for setting how
29 ffprobe will show it.
30 ffprobe output is designed to be easily parsable by a textual filter,
32 and consists of one or more sections of a form defined by the selected
33 writer, which is specified by the print_format option.
34 Sections may contain other nested sections, and are identified by a
36 name (which may be shared by other sections), and an unique name. See
37 the output of sections.
38 Metadata tags stored in the container or in the streams are recognized
40 and printed in the corresponding "FORMAT", "STREAM" or "PROGRAM_STREAM"
41 section.
42
44 All the numerical options, if not specified otherwise, accept a string
45 representing a number as input, which may be followed by one of the SI
46 unit prefixes, for example: 'K', 'M', or 'G'.
47 If 'i' is appended to the SI unit prefix, the complete prefix will be
49 interpreted as a unit prefix for binary multiples, which are based on
50 powers of 1024 instead of powers of 1000. Appending 'B' to the SI unit
51 prefix multiplies the value by 8. This allows using, for example: 'KB',
52 'MiB', 'G' and 'B' as number suffixes.
53 Options which do not take arguments are boolean options, and set the
55 corresponding value to true. They can be set to false by prefixing the
56 option name with "no". For example using "-nofoo" will set the boolean
57 option with name "foo" to false.
58 Stream specifiers
60 Some options are applied per-stream, e.g. bitrate or codec. Stream
61 specifiers are used to precisely specify which stream(s) a given option
62 belongs to.
63 A stream specifier is a string generally appended to the option name
65 and separated from it by a colon. E.g. "-codec:a:1 ac3" contains the
66 "a:1" stream specifier, which matches the second audio stream.
67 Therefore, it would select the ac3 codec for the second audio stream.
68 A stream specifier can match several streams, so that the option is
70 applied to all of them. E.g. the stream specifier in "-b:a 128k"
71 matches all audio streams.
72 An empty stream specifier matches all streams. For example, "-codec
74 copy" or "-codec: copy" would copy all the streams without reencoding.
75 Possible forms of stream specifiers are:
77 stream_index
79 Matches the stream with this index. E.g. "-threads:1 4" would set
80 the thread count for the second stream to 4. If stream_index is
81 used as an additional stream specifier (see below), then it selects
82 stream number stream_index from the matching streams. Stream
83 numbering is based on the order of the streams as detected by
84 libavformat except when a program ID is also specified. In this
85 case it is based on the ordering of the streams in the program.
86 stream_type[:additional_stream_specifier]
88 stream_type is one of following: 'v' or 'V' for video, 'a' for
89 audio, 's' for subtitle, 'd' for data, and 't' for attachments. 'v'
90 matches all video streams, 'V' only matches video streams which are
91 not attached pictures, video thumbnails or cover arts. If
92 additional_stream_specifier is used, then it matches streams which
93 both have this type and match the additional_stream_specifier.
94 Otherwise, it matches all streams of the specified type.
95 p:program_id[:additional_stream_specifier]
97 Matches streams which are in the program with the id program_id. If
98 additional_stream_specifier is used, then it matches streams which
99 both are part of the program and match the
100 additional_stream_specifier.
101 #stream_id or i:stream_id
103 Match the stream by stream id (e.g. PID in MPEG-TS container).
104 m:key[:value]
106 Matches streams with the metadata tag key having the specified
107 value. If value is not given, matches streams that contain the
108 given tag with any value.
109 u Matches streams with usable configuration, the codec must be
111 defined and the essential information such as video dimension or
112 audio sample rate must be present.
113 Note that in ffmpeg, matching by metadata will only work properly
115 for input files.
116 Generic options
118 These options are shared amongst the ff* tools.
119 -L Show license.
121 -h, -?, -help, --help [arg]

228 provide system-dependent source names that cannot be autodetected.
229 The returned list cannot be assumed to be always complete.
230 ffmpeg -sources pulse,server=192.168.0.4
232 -sinks device[,opt1=val1[,opt2=val2]...]
234 Show autodetected sinks of the output device. Some devices may
235 provide system-dependent sink names that cannot be autodetected.
236 The returned list cannot be assumed to be always complete.
237 ffmpeg -sinks pulse,server=192.168.0.4
239 -loglevel [flags+]loglevel | -v [flags+]loglevel
241 Set logging level and flags used by the library.
242 The optional flags prefix can consist of the following values:
244 repeat
246 Indicates that repeated log output should not be compressed to
247 the first line and the "Last message repeated n times" line
248 will be omitted.
249 level
251 Indicates that log output should add a "[level]" prefix to each
252 message line. This can be used as an alternative to log
253 coloring, e.g. when dumping the log to file.
254 Flags can also be used alone by adding a '+'/'-' prefix to
256 set/reset a single flag without affecting other flags or changing
257 loglevel. When setting both flags and loglevel, a '+' separator is
258 expected between the last flags value and before loglevel.
259 loglevel is a string or a number containing one of the following
261 values:
262 quiet, -8
264 Show nothing at all; be silent.
265 panic, 0
267 Only show fatal errors which could lead the process to crash,
268 such as an assertion failure. This is not currently used for
269 anything.
270 fatal, 8
272 Only show fatal errors. These are errors after which the
273 process absolutely cannot continue.
274 error, 16
276 Show all errors, including ones which can be recovered from.
277 warning, 24
279 Show all warnings and errors. Any message related to possibly
280 incorrect or unexpected events will be shown.
281 info, 32
283 Show informative messages during processing. This is in
284 addition to warnings and errors. This is the default value.
285 verbose, 40
287 Same as "info", except more verbose.
288 debug, 48
290 Show everything, including debugging information.
291 trace, 56
293 For example to enable repeated log output, add the "level" prefix,
295 and set loglevel to "verbose":
296 ffmpeg -loglevel repeat+level+verbose -i input output
298 Another example that enables repeated log output without affecting
300 current state of "level" prefix flag or loglevel:
301 ffmpeg [...] -loglevel +repeat
303 By default the program logs to stderr. If coloring is supported by
305 the terminal, colors are used to mark errors and warnings. Log
306 coloring can be disabled setting the environment variable
307 AV_LOG_FORCE_NOCOLOR, or can be forced setting the environment
308 variable AV_LOG_FORCE_COLOR.
309 -report
311 Dump full command line and log output to a file named
312 "program-YYYYMMDD-HHMMSS.log" in the current directory. This file
313 can be useful for bug reports. It also implies "-loglevel debug".
314 Setting the environment variable FFREPORT to any value has the same
316 effect. If the value is a ':'-separated key=value sequence, these
317 options will affect the report; option values must be escaped if
318 they contain special characters or the options delimiter ':' (see
319 the ``Quoting and escaping'' section in the ffmpeg-utils manual).
320 The following options are recognized:
322 file
324 set the file name to use for the report; %p is expanded to the
325 name of the program, %t is expanded to a timestamp, "%%" is
326 expanded to a plain "%"
327 level
329 set the log verbosity level using a numerical value (see
330 "-loglevel").
331 For example, to output a report to a file named ffreport.log using
333 a log level of 32 (alias for log level "info"):
334 FFREPORT=file=ffreport.log:level=32 ffmpeg -i input output
336 Errors in parsing the environment variable are not fatal, and will
338 not appear in the report.
339 -hide_banner
341 Suppress printing banner.
342 All FFmpeg tools will normally show a copyright notice, build
344 options and library versions. This option can be used to suppress
345 printing this information.
346 -cpuflags flags (global)
348 Allows setting and clearing cpu flags. This option is intended for
349 testing. Do not use it unless you know what you're doing.
350 ffmpeg -cpuflags -sse+mmx ...
352 ffmpeg -cpuflags mmx ...
353 ffmpeg -cpuflags 0 ...
354 Possible flags for this option are:
356 x86

402 -cpucount count (global)
403 Override detection of CPU count. This option is intended for
404 testing. Do not use it unless you know what you're doing.
405 ffmpeg -cpucount 2
407 -max_alloc bytes
409 Set the maximum size limit for allocating a block on the heap by
410 ffmpeg's family of malloc functions. Exercise extreme caution when
411 using this option. Don't use if you do not understand the full
412 consequence of doing so. Default is INT_MAX.
413 AVOptions
415 These options are provided directly by the libavformat, libavdevice and
416 libavcodec libraries. To see the list of available AVOptions, use the
417 -help option. They are separated into two categories:
418 generic
420 These options can be set for any container, codec or device.
421 Generic options are listed under AVFormatContext options for
422 containers/devices and under AVCodecContext options for codecs.
423 private
425 These options are specific to the given container, device or codec.
426 Private options are listed under their corresponding
427 containers/devices/codecs.
428 For example to write an ID3v2.3 header instead of a default ID3v2.4 to
430 an MP3 file, use the id3v2_version private option of the MP3 muxer:
431 ffmpeg -i input.flac -id3v2_version 3 out.mp3
433 All codec AVOptions are per-stream, and thus a stream specifier should
435 be attached to them:
436 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
438 In the above example, a multichannel audio stream is mapped twice for
440 output. The first instance is encoded with codec ac3 and bitrate 640k.
441 The second instance is downmixed to 2 channels and encoded with codec
442 aac. A bitrate of 128k is specified for it using absolute index of the
443 output stream.
444 Note: the -nooption syntax cannot be used for boolean AVOptions, use
446 -option 0/-option 1.
447 Note: the old undocumented way of specifying per-stream AVOptions by
449 prepending v/a/s to the options name is now obsolete and will be
450 removed soon.
451 Main options
453 -f format
454 Force format to use.
455 -unit
457 Show the unit of the displayed values.
458 -prefix
460 Use SI prefixes for the displayed values. Unless the
461 "-byte_binary_prefix" option is used all the prefixes are decimal.
462 -byte_binary_prefix
464 Force the use of binary prefixes for byte values.
465 -sexagesimal
467 Use sexagesimal format HH:MM:SS.MICROSECONDS for time values.
468 -pretty
470 Prettify the format of the displayed values, it corresponds to the
471 options "-unit -prefix -byte_binary_prefix -sexagesimal".
472 -of, -print_format writer_name[=writer_options]
474 Set the output printing format.
475 writer_name specifies the name of the writer, and writer_options
477 specifies the options to be passed to the writer.
478 For example for printing the output in JSON format, specify:
480 -print_format json
482 For more details on the available output printing formats, see the
484 Writers section below.
485 -sections
487 Print sections structure and section information, and exit. The
488 output is not meant to be parsed by a machine.
489 -select_streams stream_specifier
491 Select only the streams specified by stream_specifier. This option
492 affects only the options related to streams (e.g. "show_streams",
493 "show_packets", etc.).
494 For example to show only audio streams, you can use the command:
496 ffprobe -show_streams -select_streams a INPUT
498 To show only video packets belonging to the video stream with index
500 1:
501 ffprobe -show_packets -select_streams v:1 INPUT
503 -show_data
505 Show payload data, as a hexadecimal and ASCII dump. Coupled with
506 -show_packets, it will dump the packets' data. Coupled with
507 -show_streams, it will dump the codec extradata.
508 The dump is printed as the "data" field. It may contain newlines.
510 -show_data_hash algorithm
512 Show a hash of payload data, for packets with -show_packets and for
513 codec extradata with -show_streams.
514 -show_error
516 Show information about the error found when trying to probe the
517 input.
518 The error information is printed within a section with name
520 "ERROR".
521 -show_format
523 Show information about the container format of the input multimedia
524 stream.
525 All the container format information is printed within a section
527 with name "FORMAT".
528 -show_format_entry name
530 Like -show_format, but only prints the specified entry of the
531 container format information, rather than all. This option may be
532 given more than once, then all specified entries will be shown.
533 This option is deprecated, use "show_entries" instead.
535 -show_entries section_entries
537 Set list of entries to show.
538 Entries are specified according to the following syntax.
540 section_entries contains a list of section entries separated by
541 ":". Each section entry is composed by a section name (or unique
542 name), optionally followed by a list of entries local to that
543 section, separated by ",".
544 If section name is specified but is followed by no "=", all entries
546 are printed to output, together with all the contained sections.
547 Otherwise only the entries specified in the local section entries
548 list are printed. In particular, if "=" is specified but the list
549 of local entries is empty, then no entries will be shown for that
550 section.
551 Note that the order of specification of the local section entries
553 is not honored in the output, and the usual display order will be
554 retained.
555 The formal syntax is given by:
557 <LOCAL_SECTION_ENTRIES> ::= <SECTION_ENTRY_NAME>[,<LOCAL_SECTION_ENTRIES>]
559 <SECTION_ENTRY> ::= <SECTION_NAME>[=[<LOCAL_SECTION_ENTRIES>]]
560 <SECTION_ENTRIES> ::= <SECTION_ENTRY>[:<SECTION_ENTRIES>]
561 For example, to show only the index and type of each stream, and
563 the PTS time, duration time, and stream index of the packets, you
564 can specify the argument:
565 packet=pts_time,duration_time,stream_index : stream=index,codec_type
567 To show all the entries in the section "format", but only the codec
569 type in the section "stream", specify the argument:
570 format : stream=codec_type
572 To show all the tags in the stream and format sections:
574 stream_tags : format_tags
576 To show only the "title" tag (if available) in the stream sections:
578 stream_tags=title
580 -show_packets
582 Show information about each packet contained in the input
583 multimedia stream.
584 The information for each single packet is printed within a
586 dedicated section with name "PACKET".
587 -show_frames
589 Show information about each frame and subtitle contained in the
590 input multimedia stream.
591 The information for each single frame is printed within a dedicated
593 section with name "FRAME" or "SUBTITLE".
594 -show_log loglevel
596 Show logging information from the decoder about each frame
597 according to the value set in loglevel, (see "-loglevel"). This
598 option requires "-show_frames".
599 The information for each log message is printed within a dedicated
601 section with name "LOG".
602 -show_streams
604 Show information about each media stream contained in the input
605 multimedia stream.
606 Each media stream information is printed within a dedicated section
608 with name "STREAM".
609 -show_programs
611 Show information about programs and their streams contained in the
612 input multimedia stream.
613 Each media stream information is printed within a dedicated section
615 with name "PROGRAM_STREAM".
616 -show_chapters
618 Show information about chapters stored in the format.
619 Each chapter is printed within a dedicated section with name
621 "CHAPTER".
622 -count_frames
624 Count the number of frames per stream and report it in the
625 corresponding stream section.
626 -count_packets
628 Count the number of packets per stream and report it in the
629 corresponding stream section.
630 -read_intervals read_intervals
632 Read only the specified intervals. read_intervals must be a
633 sequence of interval specifications separated by ",". ffprobe will
634 seek to the interval starting point, and will continue reading from
635 that.
636 Each interval is specified by two optional parts, separated by "%".
638 The first part specifies the interval start position. It is
640 interpreted as an absolute position, or as a relative offset from
641 the current position if it is preceded by the "+" character. If
642 this first part is not specified, no seeking will be performed when
643 reading this interval.
644 The second part specifies the interval end position. It is
646 interpreted as an absolute position, or as a relative offset from
647 the current position if it is preceded by the "+" character. If the
648 offset specification starts with "#", it is interpreted as the
649 number of packets to read (not including the flushing packets) from
650 the interval start. If no second part is specified, the program
651 will read until the end of the input.
652 Note that seeking is not accurate, thus the actual interval start
654 point may be different from the specified position. Also, when an
655 interval duration is specified, the absolute end time will be
656 computed by adding the duration to the interval start point found
657 by seeking the file, rather than to the specified start value.
658 The formal syntax is given by:
660 <INTERVAL> ::= [<START>|+<START_OFFSET>][%[<END>|+<END_OFFSET>]]
662 <INTERVALS> ::= <INTERVAL>[,<INTERVALS>]
663 A few examples follow.
665 • Seek to time 10, read packets until 20 seconds after the found
667 seek point, then seek to position "01:30" (1 minute and thirty
668 seconds) and read packets until position "01:45".
669 10%+20,01:30%01:45
671 • Read only 42 packets after seeking to position "01:23":
673 01:23%+#42
675 • Read only the first 20 seconds from the start:
677 %+20
679 • Read from the start until position "02:30":
681 %02:30
683 -show_private_data, -private
685 Show private data, that is data depending on the format of the
686 particular shown element. This option is enabled by default, but
687 you may need to disable it for specific uses, for example when
688 creating XSD-compliant XML output.
689 -show_program_version
691 Show information related to program version.
692 Version information is printed within a section with name
694 "PROGRAM_VERSION".
695 -show_library_versions
697 Show information related to library versions.
698 Version information for each library is printed within a section
700 with name "LIBRARY_VERSION".
701 -show_versions
703 Show information related to program and library versions. This is
704 the equivalent of setting both -show_program_version and
705 -show_library_versions options.
706 -show_pixel_formats
708 Show information about all pixel formats supported by FFmpeg.
709 Pixel format information for each format is printed within a
711 section with name "PIXEL_FORMAT".
712 -show_optional_fields value
714 Some writers viz. JSON and XML, omit the printing of fields with
715 invalid or non-applicable values, while other writers always print
716 them. This option enables one to control this behaviour. Valid
717 values are "always"/1, "never"/0 and "auto"/"-1". Default is auto.
718 -bitexact
720 Force bitexact output, useful to produce output which is not
721 dependent on the specific build.
722 -i input_url

727 A writer defines the output format adopted by ffprobe, and will be used
728 for printing all the parts of the output.
729 A writer may accept one or more arguments, which specify the options to
731 adopt. The options are specified as a list of key=value pairs,
732 separated by ":".
733 All writers support the following options:
735 string_validation, sv
737 Set string validation mode.
738 The following values are accepted.
740 fail
742 The writer will fail immediately in case an invalid string
743 (UTF-8) sequence or code point is found in the input. This is
744 especially useful to validate input metadata.
745 ignore
747 Any validation error will be ignored. This will result in
748 possibly broken output, especially with the json or xml writer.
749 replace
751 The writer will substitute invalid UTF-8 sequences or code
752 points with the string specified with the
753 string_validation_replacement.
754 Default value is replace.
756 string_validation_replacement, svr
758 Set replacement string to use in case string_validation is set to
759 replace.
760 In case the option is not specified, the writer will assume the
762 empty string, that is it will remove the invalid sequences from the
763 input strings.
764 A description of the currently available writers follows.
766 default
768 Default format.
769 Print each section in the form:
771 [SECTION]
773 key1=val1
774 ...
775 keyN=valN
776 [/SECTION]
777 Metadata tags are printed as a line in the corresponding FORMAT, STREAM
779 or PROGRAM_STREAM section, and are prefixed by the string "TAG:".
780 A description of the accepted options follows.
782 nokey, nk
784 If set to 1 specify not to print the key of each field. Default
785 value is 0.
786 noprint_wrappers, nw
788 If set to 1 specify not to print the section header and footer.
789 Default value is 0.
790 compact, csv
792 Compact and CSV format.
793 The "csv" writer is equivalent to "compact", but supports different
795 defaults.
796 Each section is printed on a single line. If no option is specified,
798 the output has the form:
799 section|key1=val1| ... |keyN=valN
801 Metadata tags are printed in the corresponding "format" or "stream"
803 section. A metadata tag key, if printed, is prefixed by the string
804 "tag:".
805 The description of the accepted options follows.
807 item_sep, s
809 Specify the character to use for separating fields in the output
810 line. It must be a single printable character, it is "|" by
811 default ("," for the "csv" writer).
812 nokey, nk
814 If set to 1 specify not to print the key of each field. Its default
815 value is 0 (1 for the "csv" writer).
816 escape, e
818 Set the escape mode to use, default to "c" ("csv" for the "csv"
819 writer).
820 It can assume one of the following values:
822 c Perform C-like escaping. Strings containing a newline (\n),
824 carriage return (\r), a tab (\t), a form feed (\f), the
825 escaping character (\) or the item separator character SEP are
826 escaped using C-like fashioned escaping, so that a newline is
827 converted to the sequence \n, a carriage return to \r, \ to \\
828 and the separator SEP is converted to \SEP.
829 csv Perform CSV-like escaping, as described in RFC4180. Strings
831 containing a newline (\n), a carriage return (\r), a double
832 quote ("), or SEP are enclosed in double-quotes.
833 none
835 Perform no escaping.
836 print_section, p
838 Print the section name at the beginning of each line if the value
839 is 1, disable it with value set to 0. Default value is 1.
840 flat
842 Flat format.
843 A free-form output where each line contains an explicit key=value, such
845 as "streams.stream.3.tags.foo=bar". The output is shell escaped, so it
846 can be directly embedded in sh scripts as long as the separator
847 character is an alphanumeric character or an underscore (see sep_char
848 option).
849 The description of the accepted options follows.
851 sep_char, s
853 Separator character used to separate the chapter, the section name,
854 IDs and potential tags in the printed field key.
855 Default value is ..
857 hierarchical, h
859 Specify if the section name specification should be hierarchical.
860 If set to 1, and if there is more than one section in the current
861 chapter, the section name will be prefixed by the name of the
862 chapter. A value of 0 will disable this behavior.
863 Default value is 1.
865 ini
867 INI format output.
868 Print output in an INI based format.
870 The following conventions are adopted:
872 • all key and values are UTF-8
874 • . is the subgroup separator
876 • newline, \t, \f, \b and the following characters are escaped
878 • \ is the escape character
880 • # is the comment indicator
882 • = is the key/value separator
884 • : is not used but usually parsed as key/value separator
886 This writer accepts options as a list of key=value pairs, separated by
888 :.
889 The description of the accepted options follows.
891 hierarchical, h
893 Specify if the section name specification should be hierarchical.
894 If set to 1, and if there is more than one section in the current
895 chapter, the section name will be prefixed by the name of the
896 chapter. A value of 0 will disable this behavior.
897 Default value is 1.
899 json
901 JSON based format.
902 Each section is printed using JSON notation.
904 The description of the accepted options follows.
906 compact, c
908 If set to 1 enable compact output, that is each section will be
909 printed on a single line. Default value is 0.
910 For more information about JSON, see <http://www.json.org/>.
912 xml
914 XML based format.
915 The XML output is described in the XML schema description file
917 ffprobe.xsd installed in the FFmpeg datadir.
918 An updated version of the schema can be retrieved at the url
920 <http://www.ffmpeg.org/schema/ffprobe.xsd>, which redirects to the
921 latest schema committed into the FFmpeg development source code tree.
922 Note that the output issued will be compliant to the ffprobe.xsd schema
924 only when no special global output options (unit, prefix,
925 byte_binary_prefix, sexagesimal etc.) are specified.
926 The description of the accepted options follows.
928 fully_qualified, q
930 If set to 1 specify if the output should be fully qualified.
931 Default value is 0. This is required for generating an XML file
932 which can be validated through an XSD file.
933 xsd_strict, x
935 If set to 1 perform more checks for ensuring that the output is XSD
936 compliant. Default value is 0. This option automatically sets
937 fully_qualified to 1.
938 For more information about the XML format, see
940 <https://www.w3.org/XML/>.

943 ffprobe supports Timecode extraction:
944 • MPEG1/2 timecode is extracted from the GOP, and is available in the
946 video stream details (-show_streams, see timecode).
947 • MOV timecode is extracted from tmcd track, so is available in the
949 tmcd stream metadata (-show_streams, see TAG:timecode).
950 • DV, GXF and AVI timecodes are available in format metadata
952 (-show_format, see TAG:timecode).
