NAME
playdv - display digital video streams on screen
SYNOPSIS
playdv [ options ] file
DESCRIPTION
playdv reads in DV-encoded video data from file and displays it on
screen.
-v, --version
show playdv version number.
--disable-audio
skip audio decoding.
--disable-video
skip video decoding.
-n, --num-frames=count
stop playing after count frames.
--dump-frames=pattern
save a PPM image of each frame to an individual file. pattern
determines the file names and may be given in printf-style tak-
ing one numeric argument that gets replaced with the current
frame number. Like capture%05d.ppm for files capture00001.ppm,
capture00002.ppm, etc. Use - to stream the frames to stdout.
--no-mmap
don't use mmap for reading (useful for pipes).
-l, --loop-count=count
loop playback count= times, 0 for infinite.
Audio Output Options
--audio-device=devicename
target audio device; e.g. /dev/dsp, which is also the default.
--audio-file=file
send raw decoded audio stream to file, skipping audio ioctls.
Video Output Options
-d, --display=(0|1|2|3)
method used to display video data on screen: 0=autoselect
[default], 1=gtk, 2=Xv, 3=SDL. Xv is usually the fastest but
requires XFree86 version 4.0 or higher with XVideo extensions.
Decoder Options
-V, --video-system=(0|1|2|3)
sets the video standard of the incoming DV data: 0=autoselect
[default], 1=525/60 4:1:1 (NTSC), 2=625/50 4:2:0 (PAL,IEC 61834
If your machine is too slow to keep up an interactive frame
rate, you might want to decrease this number: 1=DC and no ACs,
2=DC and single-pass for ACs, 3=DC and multi-pass for ACs
[default].
-m, --monochrome
skip decoding of color blocks. Another way to speed up the
decoding process.
Audio Decode Options
-f, --frequency=(0|1|2|3)
frequency of audio data in the input stream: 0=autodetect
[default], 1=32 kHz, 2=44.1 kHz, 3=48 kHz.
-Q, --quantization=(0|1|2)
dynamic range of audio data in the input stream: 0=autodetect
[default], 1=12 bit, 2=16bit.
-e, --emphasis=(0|1|2)
first-order preemphasis of 50/15 us: 0=autodetect [default],
1=on, 2=off.
