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 optionally 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 quality but  not  neces-
	      sarily 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 generated 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 manipulation programs!

	      2)  If you are one of the poor persons with a buggy PCI bus-mastering 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 generating 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.
