demultiplex requested stream and print to standard output
SYNOPSIS
tcextract
-i name [ -x codec ] [ -t magic ] [ -a track ] [ -C

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 sup-
ported). 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.
