\fBtcextract\fP reads source (from stdin if not explicitely defined) and
prints on the standard output.
.SH OPTIONS

.IP "\fB-t \fImagic\fP"
source file magic. This option is used to identify the source file format if reading is performed from stdin or \fItcextract\fP fails to identify the source
file format. Supported formats are labeled with \fImagic\fP:
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
.IP "\fB-x \fIcodec\fP"
source pdeudo-codec, if not detected when reading from stdin. Currently, supported parameter for \fIcodec\fP are
mp3 MPEG audio
ac3 AC3 audio
a52 A52 audio
