DESCRIPTION

   tcextract is part of and usually called by transcode.
   However, it can also be used independently.
   tcextract  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.   tcextract
          reads streams from file or from stdin.

   -C s-e extract  and print out only this frame interval (video) or bytes
          (audio) [all]. This option  is  only  supported  if  the  source
          contains proper information to perform a selective extraction.

   -t magic
          source  file  magic.  This option is used to identify the source
          file format if reading is  performed  from  stdin  or  tcextract
          fails  to identify the source file format. Supported formats are
          labeled with magic:

          avi       RIFF AVI-file

          vob       MPEG program streams

          m2v       MPEG elementary video stream

          vdr       MPEG digital video recording

          raw       raw bitstream

          wav       RIFF WAVE audio

          yuv4mpeg  mjpeg-tools stream header format

   -x codec
          source pdeudo-codec, if not detected when  reading  from  stdin.
          Currently, supported parameter for codec are

          mp3       MPEG audio

          ac3       AC3 audio

          a52       A52 audio

          dv        Digital Video DV

          mpeg2          MPEG video

          yv12      Y'CbCr YUV

          rgb       RGB 24-bit

          ps1       MPEG private stream (subtitles)

          pcm       raw audio stream

   -a track
          extract selected audio or video track from source.

   -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

   tcextract  is  a  front  end  for  extracting  various  raw  or encoded
   audio/video tracks from a source and  is  used  in  transcode's  import
   pipeline.

EXAMPLES

   The  command tcextract -i foo.avi -x mp3 -a 3 extracts MPEG audio track
   3 from the AVI-file foo.avi and prints the bitstream to stdout.
