       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 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.

              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.

       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

       -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.
