       tcdecode - read multimedia streams from medium, decode to raw format and print to standard
       output

SYNOPSIS

       tcdecode
              -i name [ -x codec ] [ -t package ] [ -g WxH ] [ -s c,f,r ] [ -C s-e ] [ -y codec ]
              [ -Y ] [ -Q mode ] [ -A flag ] [ -d verbosity ] [ -v ]

DESCRIPTION

       tcdecode is part of and usually called by transcode.
       However, it can also be used independently.
       tcdecode  reads  source (from stdin if not explicitely defined) and prints on the standard
       output.

OPTIONS

       -i name
              Specify input source.  If ommited, stdin is assumed.  tcdecode reads  streams  from
              file or from stdin.

       -g WxH video frame width and height [720x576]

       -C s-e decode and print out only this frame interval (video) or bytes (audio) [all].

       -x codec
              source  codec,  if  not  detected of reading from stdin. This option also specifies
              video and audio context of the source for decoding. Currently, supported  parameter
              for codec are

               mp3        MPEG audio      (lame)
               ac3        AC3 audio       (liba52)
               dv      Digital Video DV   (libdv)
               mpeg2      MPEG video      (libmpeg2)
               yv12       Y'CbCr YUV
               mov        Quicktime       (libquicktime)

       -t package
              Currently only argument supported is "lavc". Use the codec by -x from this package.
              Available (-x) codecs for lavc are: mpeg2, divx3, divx, divx4,  mp42,  mjpg,  rv10,
              svq1, svq3, vp3, 4xm, wmv1, wmv2, hfyu, indeo3, h263p, h263i

       -y codec
              target  codec.   tcdecode  only decodes to raw format suitable for transcode. Valid
              option parameter for codec are

               rgb              RGB 24bit
               yv12            Y'CbCr YUV
               yuy2             4:2:2 YUV
               pcm    SIGNED LE 16bit PCM

       -s c,f,r
              audio gain for AC3 downmixing [1.0,1.0,1.0]

       -Y     decoded Digital Video (raw) YUV frame is  in  YUY2  (packet)  format  using  libdv.
              Downsample  frame  to YV12. PAL users should compile libdv with --with-pal-yuv=YV12
              to avoid this option [off]

       -A flag
              audio flag for  AC3/A52  decoder  [none].  This  flag  determines  the  down-mixing
              configuration. Valid choices for flag are determined by the following bits set:

               drc off     1
               demux       2
               dolby off   4

       Add those numbers to turn multiple options on.

       -Q mode
              decoding  quality.  Certain  codecs,  e.g.,  DV  with libdv allow for changing this
              parameter if speed is prefered over quality.  Valid parameter are  1=fastest-5=best
              [5].

       -d level
              With  this option you can specify a bitmask to enable different levels of verbosity
              (if supported).  You can combine several levels by adding the corresponding values:

               QUIET       0
               INFO        1
               DEBUG       2
               STATS       4
               WATCH       8
               FLIST      16
               VIDCORE    32
               SYNC       64
               COUNTER   128
               PRIVATE   256

       -v     Print version information and exit.

NOTES

       tcdecode is a front end for decoding various sources and is used in transcode(1)'s  import
       modules.

EXAMPLES

       The command
              tcdecode -i foo.mp3 -x mp3
       decodes an MPEG audio stream and prints raw PCM data to stdout.

       The command
              tcextract -i foo.avi -x mp3 | tcdecode -x mp3
       extracts  an  MPEG  audio  track  from  the AVI-file foo.avi and pipes the frames into the
       decoder
