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 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
