+
+@chapter Description
+@c man begin 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 filename is specified in input, ffprobe will try to open and
+probe the file content. If the file cannot be opened or recognized as
+a multimedia file, a positive exit code is returned.
+
+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 @option{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 @option{sections}.
+
+Metadata tags stored in the container or in the streams are recognized
+and printed in the corresponding "FORMAT" or "STREAM" section.

+@chapter Options
+@c man begin OPTIONS
+
+@include avtools-common-opts.texi
+
+@section Main options
+
+@table @option
+
+@item -f @var{format}
+Force format to use.
+
+@item -unit
+Show the unit of the displayed values.
+
+@item -prefix
+Use SI prefixes for the displayed values.
+Unless the "-byte_binary_prefix" option is used all the prefixes
+are decimal.
+
+@item -byte_binary_prefix
+Force the use of binary prefixes for byte values.
+
+@item -sexagesimal
+Use sexagesimal format HH:MM:SS.MICROSECONDS for time values.
+
+@item -pretty
+Prettify the format of the displayed values, it corresponds to the
+options "-unit -prefix -byte_binary_prefix -sexagesimal".
+
+@item -of, -print_format @var{writer_name}[=@var{writer_options}]
+Set the output printing format.
+
+@var{writer_name} specifies the name of the writer, and
+@var{writer_options} specifies the options to be passed to the writer.
+
+For example for printing the output in JSON format, specify:
+@example
+-print_format json
+@end example
+
+For more details on the available output printing formats, see the
+Writers section below.
+
+@item -sections
+Print sections structure and section information, and exit. The output
+is not meant to be parsed by a machine.
+
+@item -select_streams @var{stream_specifier}
+Select only the streams specified by @var{stream_specifier}. This
+option affects only the options related to streams
+(e.g. @code{show_streams}, @code{show_packets}, etc.).
+
+For example to show only audio streams, you can use the command:
+@example
+ffprobe -show_streams -select_streams a INPUT
+@end example
+
+To show only video packets belonging to the video stream with index 1:
+@example
+ffprobe -show_packets -select_streams v:1 INPUT
+@end example
+
+@item -show_data
+Show payload data, as an hexadecimal and ASCII dump. Coupled with
+@option{-show_packets}, it will dump the packets' data. Coupled with
+@option{-show_streams}, it will dump the codec extradata.
+
+The dump is printed as the "data" field. It may contain newlines.
+
+@item -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".
+
+@item -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".
+
+@item -show_format_entry @var{name}
+Like @option{-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 @code{show_entries} instead.
+
+@item -show_entries @var{section_entries}
+Set list of entries to show.
+
+Entries are specified according to the following
+syntax. @var{section_entries} contains a list of section entries
+separated by @code{:}. 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 @code{,}.
+
+If section name is specified but is followed by no @code{=}, 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 @code{=} 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:
+@example
+@var{LOCAL_SECTION_ENTRIES} ::= @var{SECTION_ENTRY_NAME}[,@var{LOCAL_SECTION_ENTRIES}]
+@var{SECTION_ENTRY} ::= @var{SECTION_NAME}[=[@var{LOCAL_SECTION_ENTRIES}]]
+@var{SECTION_ENTRIES} ::= @var{SECTION_ENTRY}[:@var{SECTION_ENTRIES}]
+@end example
+
+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:
+@example
+packet=pts_time,duration_time,stream_index : stream=index,codec_type
+@end example
+
+To show all the entries in the section "format", but only the codec
+type in the section "stream", specify the argument:
+@example
+format : stream=codec_type
+@end example
+
+To show all the tags in the stream and format sections:
+@example
+format_tags : format_tags
+@end example
+
+To show only the @code{title} tag (if available) in the stream
+sections:
+@example
+stream_tags=title
+@end example
+
+@item -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".
+
+@item -show_frames
+Show information about each frame contained in the input multimedia
+stream.
+
+The information for each single frame is printed within a dedicated
+section with name "FRAME".
+
+@item -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".
+
+@item -count_frames
+Count the number of frames per stream and report it in the
+corresponding stream section.
+
+@item -count_packets
+Count the number of packets per stream and report it in the
+corresponding stream section.
+
+@item -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.
+
+@item -show_program_version
+Show information related to program version.
+
+Version information is printed within a section with name
+"PROGRAM_VERSION".
+
+@item -show_library_versions
+Show information related to library versions.
+
+Version information for each library is printed within a section with
+name "LIBRARY_VERSION".
+
+@item -show_versions
+Show information related to program and library versions. This is the
+equivalent of setting both @option{-show_program_version} and
+@option{-show_library_versions} options.
+
+@item -bitexact
+Force bitexact output, useful to produce output which is not dependent
+on the specific build.
+
+@item -i @var{input_file}
+Read @var{input_file}.
+
+@end table
+@c man end
+
+@chapter Writers
+@c man begin WRITERS
+
+A writer defines the output format adopted by @command{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 @var{key}=@var{value}
+pairs, separated by ":".
+
+A description of the currently available writers follows.
+
+@section default
+Default format.
+
+Print each section in the form:
+@example
+[SECTION]
+key1=val1
+...
+keyN=valN
+[/SECTION]
+@end example
+
+Metadata tags are printed as a line in the corresponding FORMAT or
+STREAM section, and are prefixed by the string "TAG:".
+
+A description of the accepted options follows.
+
+@table @option
+
+@item nokey, nk
+If set to 1 specify not to print the key of each field. Default value
+is 0.
+
+@item noprint_wrappers, nw
+If set to 1 specify not to print the section header and footer.
+Default value is 0.
+@end table
+
+@section compact, csv
+Compact and CSV format.
+
+The @code{csv} writer is equivalent to @code{compact}, but supports
+different defaults.
+
+Each section is printed on a single line.
+If no option is specifid, the output has the form:
+@example
+section|key1=val1| ... |keyN=valN
+@end example
+
+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.
+
+@table @option
+
+@item 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 @code{csv} writer).
+
+@item nokey, nk
+If set to 1 specify not to print the key of each field. Its default
+value is 0 (1 for the @code{csv} writer).
+
+@item escape, e
+Set the escape mode to use, default to "c" ("csv" for the @code{csv}
+writer).
+
+It can assume one of the following values:
+@table @option
+@item 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 @var{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 @var{SEP} is
+converted to "\@var{SEP}".
+
+@item csv
+Perform CSV-like escaping, as described in RFC4180. Strings
+containing a newline ('\n'), a carriage return ('\r'), a double quote
+('"'), or @var{SEP} are enclosed in double-quotes.
+
+@item none
+Perform no escaping.
+@end table
+
+@item print_section, p
+Print the section name at the begin of each line if the value is
+@code{1}, disable it with value set to @code{0}. Default value is
+@code{1}.
+
+@end table
+
+@section 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 @var{sep_char} option).
+
+The description of the accepted options follows.
+
+@table @option
+@item 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 '.'.
+
+@item 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.
+@end table
+
+@section ini
+INI format output.
+
+Print output in an INI based format.
+
+The following conventions are adopted:
+
+@itemize
+@item
+all key and values are UTF-8
+@item
+'.' is the subgroup separator
+@item
+newline, '\t', '\f', '\b' and the following characters are escaped
+@item
+'\' is the escape character
+@item
+'#' is the comment indicator
+@item
+'=' is the key/value separator
+@item
+':' is not used but usually parsed as key/value separator
+@end itemize
+
+This writer accepts options as a list of @var{key}=@var{value} pairs,
+separated by ":".
+
+The description of the accepted options follows.
+
+@table @option
+@item 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.
+@end table
+
+@section json
+JSON based format.
+
+Each section is printed using JSON notation.
+
+The description of the accepted options follows.
+
+@table @option
+
+@item compact, c
+If set to 1 enable compact output, that is each section will be
+printed on a single line. Default value is 0.
+@end table
+
+For more information about JSON, see @url{http://www.json.org/}.
+
+@section xml
+XML based format.
+
+The XML output is described in the XML schema description file
+@file{ffprobe.xsd} installed in the FFmpeg datadir.
+
+An updated version of the schema can be retrieved at the url
+@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
+@file{ffprobe.xsd} schema only when no special global output options
+(@option{unit}, @option{prefix}, @option{byte_binary_prefix},
+@option{sexagesimal} etc.) are specified.
+
+The description of the accepted options follows.
+
+@table @option
+
+@item 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.
+
+@item xsd_compliant, x
+If set to 1 perform more checks for ensuring that the output is XSD
+compliant. Default value is 0.
+This option automatically sets @option{fully_qualified} to 1.
+@end table
