tcextract — read multimedia file from medium, extract or demultiplex requested stream and print to standard output

Synopsis

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

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:

aviRIFF AVI-file
vobMPEG program streams
m2vMPEG elementary video stream
vdrMPEG digital video recording
rawraw bitstream
wavRIFF WAVE audio
yuv4mpegmjpeg-tools stream header format
-x codec

source pdeudo-codec, if not detected when reading from stdin. Currently, supported parameter for codec are

mp3MPEG audio
ac3AC3 audio
a52A52 audio
dvDigital Video DV
mpeg2MPEG video
yv12Y'CbCr YUV
rgbRGB 24-bit
ps1MPEG private stream (subtitles)
pcmraw 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.
