       playdv - display digital video streams on screen

       playdv [ options ] file

       playdv reads in DV-encoded video data from file and displays it on screen.

       -v, --version
	      show playdv version number.

	      skip audio decoding.

	      skip video decoding.

       -n, --num-frames=count
	      stop playing after count frames.

	      save  a  PPM image of each frame to an individual file. pattern determines the file
	      names and may be given in  printf-style  taking  one  numeric  argument  that  gets
	      replaced	with  the  current  frame  number.  Like  capture%05d.ppm  for files cap-
	      ture00001.ppm, capture00002.ppm, etc.  Use - to stream the frames to stdout.

	      don't use mmap for reading (useful for pipes).

       -l, --loop-count=count
	      loop playback count= times, 0 for infinite.

       Audio Output Options

	      target audio device; e.g. /dev/dsp, which is also the default.

	      send raw decoded audio stream to file, skipping audio ioctls.

       --audio-mix=(-16 .. 16)
	      mixing level of 4 channel audio for 32KHz 12bit. 0 [default].  -16  selects  second
	      channel, 16 selects first channel.

       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.

	      video display aspect ratio (for Xv only): n=normal 4:3, w=wide 16:9 .  Not all win-
	      dow manager support resizing at fixed aspect ratio. If they do, resizing is done at
	      fixed aspect ratio.

       --size=(10 .. 100)
	      initial scaleing percentage (for Xv only): 10 <= n <= 100.

       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 DV),	3=625/50  4:1:1  (PAL,SMPTE  314M
	      DV).  Autoselect	usually works fine. Only use this option if you know what you are

       Video Decode Options

       -q, --quality=(1|2|3)
	      quality level of desired video decoding.	The process of decoding DV data is  split
	      into  several  steps.   Each additional step enhances output quality, but of course
	      also slows down decoding.  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 sin-
	      gle-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,

       -e, --emphasis=(0|1|2)
	      first-order preemphasis of 50/15 us: 0=autodetect [default], 1=on, 2=off.

       Help Options

       -?, --help
	      Show help message. Use this  command  to	get  a	brief  description  of	available

	      Display brief usage message.
