@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 any INI or JSON |
|
parsers. |
