Add FFprobe tool.
This is a simplified / cleaned-up version of the SourceForge program: http://sourceforge.net/projects/ffprobe/ Syntax / features may be different, in particular the options -show_packets and -show_frames are not yet supported in this version.

@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:''.
|
||||

||||

|
||||
|
||||
@section Main options
|
||||
|
||||
@table @option
|
||||
@item -unit
|
||||
Show the unit of the displayed values.
|
||||
|
||||
@item -prefix
|
||||
Show a SI prefixes of the displayed values.
|
||||
Unless ``-byte_binary_prefix'' option is used all the prefix
|
||||
are decimal.
|
||||
|
||||
@item -byte_binary_prefix
|
||||
Force the use of binary prefixes for byte values.
|
||||
|
||||
@item -sexagesimal
|
||||
Use sexagesimal format HH:MM:SS.MICROSECONDS for time values.
|
||||
|
||||
@item -pretty
|
||||
Prettify the format of the displayed values, it corresponds to the
|
||||
options ``-unit -prefix -byte_binary_prefix -sexagesimal''.
|
||||
|
||||
@item -show_format
|
||||
Show information about the container format of the input multimedia
|
||||
stream.
|
||||
|
||||
All the container format information is printed within a section with
|
||||
name ``FORMAT''.
|
||||
|
||||
@item -show_streams
|
||||
Show information about each media stream contained in the input
|
||||
multimedia stream.
|
||||
|
||||
Each media stream information is printed within a dedicated section
|
||||
with name ``STREAM''.
