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
