+
+@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:".
