encodedv




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 pic­
              tures. This is ignored by most  image  manipulation
              programs!
              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  differ­
              ently.

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

       -o, --output=filter-name
              Choose  output-filter: [>raw<] Hint for Arne Schir­
              macher to add AVI support ;-)

       -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
