       plugger - a streaming multimedia plugin for UNIX netscape
       pluggerrc - configure file for plugger

       Plugger	is  a	Netscape  plugin which can show many types of multimedia inside your Net-
       scape. To accomplish this, Plugger uses external programs such as xanim, mtv, timidity and

       For    up-to-date    information    on	 Plugger,    see    the    plugger   home   page:

       You can configure plugger by changing the file pluggerrc which can be located  in  any  of
       the following directories:


       The  format  of	pluggerrc is very simple. The general layout is to have one or more lines
       describing mime-types followed by one or more lines describing  commands  used  to  handle
       those  mime-types. Lines beginning with # are considered comments and are ignored. Here is
       a simple example:

	    video/mpeg; mpeg; Mpeg video
	    video/quicktime; qt; Mpeg video
		 : xanim +W$window -Zr +q +Ze +f $file

	    audio/mpeg2: mp2: MPEG audio
	    audio/x-mpeg2: mp2: MPEG audio
	    audio/mpeg3: mp3: MPEG audio
	    audio/x-mpeg3: mp3: MPEG audio
	    audio/mpeg: mpa,abs,mpega: MPEG audio
	    audio/x-mpeg: mpa,abs,mpega: MPEG audio
		 stream, preload: mpg123 -q -b 128 -
		 many: splay -t 200 $file
		 many: amp -b 200 -q $file

       Each line describing a mime type has three fields:

	     mime type ; extensions ; description

       mime type
	      The mime type is the standardized name for the content type  you	want  Plugger  to
	      handle.  This  must  be  the  same type as the web server claims the file to be, or
	      Plugger will not be used for that file, regardless of the extension.

	      This is a comma separated list of extensions that should be  associated  with  this
	      particular  mime	type.  The  extensions	are  only used when a web server does not
	      report what type of file it is, or when loading files directly from disk.

	      This is the description that shows up in about:plugins and in the application pref-
	      erences section in Netscape.

	      Lines  that  describe  what command to use for a mime type must begin with a white-
	      space and have two fields:

		    flags : command

       flags  This is a comma-separated list of flags which tells plugger how to handle this par-
	      ticular application. See below for further details.

	      This is a command which is sent to /bin/sh when handling this mime type.

       When Plugger is called from netscape, it looks through the configuration file and tries to
       find a matching mime type. For an application to be chosen it has to fulfill certain  cri-
       teria, it has to exist, and it must match the flags given to plugger.

       When  it does, it tries to figure out which command to use. If the input is streamable, it
       looks through all the commands for that particular mime type to see  if	it  can  find  an
       application  that  has the stream flag. If it cannot find a streaming application it down-
       loads the file and tries again. Note that Plugger will check the first word of the command
       and  search  your  $PATH for that command. If that command is not found Plugger will go to
       the next line in your pluggerrc.

       repeat This indicates that the command uses the $repeat variable. If  this  flag  is  set,
	      Plugger will only start the application once.

       loop   This indicates that the application loops forever. If the <EMBED> tag used to start
	      Plugger indicated that the file should not loop forever, the command on  this  line
	      will not be used.

       stream This  indicates  that  this  command takes input on stdin.  Plugger will attempt to
	      stream data as it is being downloaded and send it to  the  application.  Note  that
	      streaming  applications can also be used to play files and data which is already in
	      your netscape cache.

	      This flag is only meaningful in when used together with the stream flag.	It  tells
	      plugger  to  preload  a buffer with 40000 bytes of data before starting to play the
	      file. If the buffer runs out, Plugger will stop sending  data  to  the  application
	      until the buffer is full again. This is usually a good thing for streaming sound.

       many   This  indicates  that the application can accept several files on the command line.
	      Using this option can reduce clicks, choppiness and machine load, but it	is  never

	      This options tells Plugger to ignore the exit status of the application.

       exits  This  option tells Plugger that the application exits, but should not be restarted.
	      This can be used with applications which automatically forks into the background.

       nokill This will tell plugger not to try to kill the application when  leaving  the  page.
	      This  is	normally  used	for programs which start in their own window and can play
	      multiple files, such as xmms.

       swallow ( name )
	      This is the only option that takes an argument so far. It will  tell  plugger  that
	      the  application	will  open  a window with the specified name and that this window
	      will then be moved to inside your browser.

       Plugger gives some variables to /bin/sh when starting  the  application,  these	variables

	      This  variable  contains	how  many  times the file should be played.  Applications
	      which use this variable should also set the repeat flag.

	      This is the X window Netscape has given the plugin. This can be used with  applica-
	      tions such as xanim to display graphics inside the netscape window.

       $file  This  is	the  file  to  play. This variable is not set if the application uses the
	      stream flag. It may also be more than one file if you use the many flag.

	      This variable contains the mime type of $file.

       You have to remove ~/.netscape/plugin-list after changing the  configuration,  or  nothing
       will happen. This is a netscape bug, not a Plugger bug.

       Netscape  3.x  will not play anything for <EMBED> tags for which height or width are zero.
       This too is a Netscape bug.
