  16. @c man begin DESCRIPTION
  17. FFprobe gathers information from multimedia streams and prints it in
  18. human- and machine-readable fashion.
  19. For example it can be used to check the format of the container used
  20. by a multimedia stream and the format and type of each media stream
  21. contained in it.
  22. If a filename is specified in input, ffprobe will try to open and
  23. probe the file content. If the file cannot be opened or recognized as
  24. a multimedia file, a positive exit code is returned.
  25. FFprobe may be employed both as a standalone application or in
  26. combination with a textual filter, which may perform more
  27. sophisticated processing, e.g. statistical processing or plotting.
  28. Options are used to list some of the formats supported by ffprobe or
  29. for specifying which information to display, and for setting how
  30. ffprobe will show it.
  31. FFprobe output is designed to be easily parsable by a textual filter,
  32. and consists of one or more sections of the form:
  33. @example
  34. [SECTION]
  35. key1=val1
  36. ...
  37. keyN=valN
  38. [/SECTION]
  39. @end example
  40. Metadata tags stored in the container or in the streams are recognized
  41. and printed in the corresponding ``FORMAT'' or ``STREAM'' section, and
  42. are prefixed by the string ``TAG:''.
