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
