@chapter Synopsis

The generic syntax is:

@example

@c man begin SYNOPSIS

ffprobe [options] [@file{input_file}]

@c man end

@end example

@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 the form:

@example

[SECTION]

key1=val1

...

keyN=valN

[/SECTION]

@end example

Metadata tags stored in the container or in the streams are recognized

and printed in the corresponding "FORMAT" or "STREAM" section, and

are prefixed by the string "TAG:".
