@chapter Description
@c man begin DESCRIPTION
2011-07-26 17:04:43 +00:00
avprobe 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.
2011-07-26 17:04:43 +00:00
If a filename is specified in input, avprobe 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.
2011-07-26 17:04:43 +00:00
avprobe 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.
2011-07-26 17:04:43 +00:00
Options are used to list some of the formats supported by avprobe or
for specifying which information to display, and for setting how
2011-07-26 17:04:43 +00:00
avprobe will show it.
2011-07-26 17:04:43 +00:00
avprobe 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:".
