21@c man begin DESCRIPTION
22
23FFprobe gathers information from multimedia streams and prints it in
24human- and machine-readable fashion.
25
26For example it can be used to check the format of the container used
27by a multimedia stream and the format and type of each media stream
28contained in it.
29
30If a filename is specified in input, ffprobe will try to open and
31probe the file content. If the file cannot be opened or recognized as
32a multimedia file, a positive exit code is returned.
33
34FFprobe may be employed both as a standalone application or in
35combination with a textual filter, which may perform more
36sophisticated processing, e.g. statistical processing or plotting.
37
38Options are used to list some of the formats supported by ffprobe or
39for specifying which information to display, and for setting how
40ffprobe will show it.
41
42FFprobe output is designed to be easily parsable by a textual filter,
43and consists of one or more sections of the form:
44@example
45[SECTION]
46key1=val1
47...
48keyN=valN
49[/SECTION]
50@end example
51
52Metadata tags stored in the container or in the streams are recognized
53and printed in the corresponding ``FORMAT'' or ``STREAM'' section, and
54are prefixed by the string ``TAG:''.
