    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.
