SYNOPSIS

tcextract
  -i name [ -x codec ] [ -t magic ] [ -a track ] [ -C s-e ] [ -d verbosity ] [ -v ]

COPYRIGHT

tcextract is Copyright (C) by Thomas Oestreich.

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.
