       playdv - display digital video streams on screen


       playdv [ options ] file


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

       -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 capture00001.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 window 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 doing.

       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 single-pass for ACs, 3=DC and multi-pass  for  ACs

       -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.

       Help Options

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