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 necessarily slower encoding! This defaults for best qual-
	      ity = 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 cap-
	      turing  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

       --usage
	      Display brief usage message.
