    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 decoding. Currently, supported parameter for codec are

    mp3MPEG audio(lame)
    ac3AC3 audio(libac3)
    a52A52 audio(liba52)
    dvDigital Video DV(libdv)
    mpeg2MPEG video(libmpeg2)
    yv12Y'CbCr YUV
    af6audioaudio API(avifile)
    af6videovideo API(avifile)
    movQuicktime(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

    rgbRGB 24bit
    yv12Y'CbCr YUV
    yuy24:2:2 YUV
    pcmSIGNED 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 off1
    demux2
    dolby off4

    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:

    QUIET0
    INFO1
    DEBUG2
    STATS4
    WATCH8
    FLIST16
    VIDCORE32
    SYNC64
    COUNTER128
    PRIVATE256

    -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
