NAME
       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	decod‐
	      ing. Currently, supported parameter for codec are

	       ac3     AC3 audio	       (liba52)
	       dv      Digital Video DV	       (libdv)
	       lzo     LZO compressed video    (liblzo)
	       mov     Quicktime	       (libquicktime)
	       mp2     MPEG audio	       (lame)
	       mp3     MPEG audio	       (lame)
	       mpeg2   MPEG video	       (libmpeg2)
	       ogg     Vorbis audio	       (libvorbis)
	       ulaw    u-Law PCM audio
	       yv12    Y'CbCr YUV

       -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
