@chapter Introduction
|
|
|
|
@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:''.
