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
