It will be further developed with a few incompatible changes. ffmpeg.c will stay as is for some time, so any scripts using it won't be broken.

@chapter Synopsis

The generic syntax is:
|
|
|
|
@example
|
|
@c man begin SYNOPSIS
|

avprobe [options] [@file{input_file}]
|
|
@c man end

@chapter Description
|
|
@c man begin DESCRIPTION
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
Options are used to list some of the formats supported by avprobe or
|
|
for specifying which information to display, and for setting how
|
|
avprobe will show it.
|
|
|
|
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:".
