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.
-dlevel
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.
