====== xjinfo - extract an A/V file information ======

''xjinfo'' is a small command-line utility that comes with [[xjadeo]]. Its purpose it to retrieve information about audio/video files in a standard way: either CSV, XML or simplified human readable text. A DTD for the XML is available from the [[http://xjadeo.svn.sourceforge.net/viewvc/xjadeo/trunk/src/xjadeo/avinfo.dtd?revision=112|repository]].

''xjinfo'' uses ffmpeg's libavformat to determine the information. Basically it can read any format ffmpeg supports (''ffmpeg -formats'').

  usage: xjinfo [Options] <video-file>
  Options:
    -h   display this help and exit
    -V   print version information and exit
    -x   print XML (default).
    -t   print duration of file in seconds.
    -v   dump human readable video stream information.
    -c   dump comma separated video stream information.
         one line for each video stream:
          file-duration,file-fps,stream-fps,width,height,codec,colorspace
         Units: file-len: sec; fps: 1/sec; w&h: pixels; codec+fmt: text

===== Example Output: =====

  * "Human readable":
  00:04:37.4 - fps:25.00 w:352 h:264 #mpeg1video,yuv420p

  * Comma separated value:

  * "duration only" (in seconds):
  277
