NAME

ffprobe - FFprobe media prober

SYNOPSIS

ffprobe [options] [input_file]

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:

         [SECTION]
         key1=val1
         ...
         keyN=valN
         [/SECTION]

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:''.
