       standard output

SYNOPSIS

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.
