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

mp3 MPEG audio (lame)
ac3 AC3 audio (liba52)
dv Digital Video DV (libdv)
mpeg2 MPEG video (libmpeg2)
yv12 Y'CbCr YUV
mov Quicktime (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

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
