NAME
       encodedv	- encode a series of images to a digital video stream

SYNOPSIS
       encodedv	[ options ] video_pattern [ audio_input	]

DESCRIPTION
       encodedv	 takes	a series of images in PPM/PGM/video format and option-
       ally an audio stream and	compiles them into a DV-encoded	video  stream.
       pattern	specifies  where the input data	is located and may be either -
       for stdin, or a printf-style pattern taking one numeric	argument  that
       gets  replaced  by the current frame number.  Like image%03d.ppm, which
       gets expanded to	image000.ppm, image001.ppm, etc.

       --version
	      show encodedv version number.

       -s, --start-frame=count
	      start encoding at	frame number count (defaults to	0).

       -e, --end-frame=count
	      end encoding at frame number count (defaults to unlimited).

       -l, --wrong-interlace
	      flip lines to compensate for  wrong  interlacing	in  the	 input
	      data. Happened with mpeg2dec generated data.

       -p, --vlc-passes
	      vlc code distribution passes (1-3) greater values	= better qual-
	      ity but not necessarily slower encoding! This defaults for  best
	      quality =	3.

       -v, --verbose
	      show encoder statistics /	status information

       -i, --input=filter-name
	      Choose  input-filter:  [>ppm<,  pgm,  video] The ppm-filter only
	      supports raw rgb ppm files.  The pgm file	format is the one gen-
	      erated by	mpeg2dec of the	livid project. ( http://linuxvideo.org
	      )	This means: Y-data appended by U and V data which  are	scaled
	      down  by 2 and placed side by side. This option defaults to PPM.
	      Some things you want to keep in mind:

	      1) If you	want to	stream video  frames  (using  video_pattern  =
	      "-")  you	have to	make sure that there is	no trailing garbage at
	      the end of the pictures. This is ignored by most image manipula-
	      tion programs!

	      2)  If you are one of the	poor persons with a buggy PCI bus-mas-
	      tering board be sure to have a backup handy if you want  to  use
	      video  support.  Some  versions  of the VIA board	chipsets crash
	      your machine and even your harddisk. Since  encodedv  uses  full
	      resolution  capturing  it	 is  more likely to trigger these bugs
	      than other programs. If you have a VIA board you definitely want
	      to upgrade to Linux 2.4.3	or higher.

	      3)  The  encoded	pictures  must have the	correct	resolution. If
	      they don't, you may want to try ppmqscale. The used video	format
	      is chosen	by picture resolution. Use 720x576 for PAL and 720x480
	      for NTSC.

	      4) If you	want to	speed up things	a little bit and you are  gen-
	      erating  the  input  pictures  automatically you may want	to try
	      pgm's instead of ppm's since they	are encoded  somewhat  faster.
	      But  keep	 in mind, that this pgm	format is only optimal for PAL
	      since NTSC averages the U	and V values somewhat differently.

       -a, --audio-input=filter-name
	      Choose audio-input-filter: [>none<, wav, dsp]

       -o, --output=filter-name
	      Choose output-filter: [>raw<]

       -q, --static-qno=table-no
	      Static qno tables	for quantisation on 2 VLC passes.   For	 turbo
	      (but  somewhat lossy encoding) try -q [1,2] -p [2,3].  There are
	      only two static qno tables registered right now:

	      1	: for sharp DV pictures

	      2	: for somewhat noisy satelite television signal

	      If you want to add some more, go ahead ;-)

       -f, --fps=fps-number
	      Set frames per second (default: use all frames)

       -d, --force-dct=dct-mode
	      Force dct	mode (88 or 248) for whole picture

       Help Options

       -?, --help
	      Show help	message.

       --usage
	      Display brief usage message.
