Specify the input file type magic. Useful for
using tcdemux in pipelines. This is normally
Process only packets containing given audio track
ach and video track vch. Most program stream fea-
ture multiple audio tracks but only a single video
stream. Default is "-a 0,0".
Select specific multimedia track using the standard
identifier 0xnn. This useful to extract subtitle
-f fps Specify the frame rate fps for subtitle meta infor-
mation used by external applications.
Select a program unit unit and a selected GOP range
s1-s2 for processing. A unit is usually a set of
GOPs that need to be synchronized at the very
beginning. This option can be used to eleminate
junk units at the beginning of the main presenta-
tion or to select certain episodes of a TV series
from a DVD. A GOP is a logical unit to be properly
decoded, i.e., decoding can only start at the
beginning of a GOP.
-O Do not skip initial sequence. Used internally by
Select packets using an identifier for extracting
only selected streams without processing. This is
useful for size reduction of your multimedia
tcdemux -i big_dvd.vob -A 0xe0,0x81,0x20 >
extracts all packets for the video stream, AC3
audio track (1) and the first subtitle stream (0).
Select synchronization strategy mode. This is how
transcode selects the beginning of a video and
audio stream to assure both streams are sychronized
for further processing:
0 no synchronization. Packets are printed
directly to stdout.
1 synchronization based on PTS information found
in the packet header. Audio packets are delayed
until a suitable starting point is found. Default
for PAL videos.
2 NTSC adapted synchronization mode. Detailed
information for each GOP contained in the video
stream are piped to a stdout to be processed by the
certain import modules. This enables adjusting the
frame rate or inverse telecine, if necessary.
3 more advanced synchronization mode 1 with
msec granular adjustment. Details delegated to
4 more advanced synchronization mode 2 with
msec granular adjustment for NTSC materail. Details
delegated to transcode.
5-7 undocumented debugging modes for internal use.
Write GOP meta information to file instead of
-W Print a navigation log file for a given video
stream to stdout. This is used for transcode's "psu
mode" and "cluster mode".
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:
-v Print version information and exit.
tcdemux is a front end for de-multiplexing program streams
and is used in transcode's import modules.
tcprobe -i movie.vob -x mpeg2
extracts only MPEG video packets. Further processing,
i.e., extracting the elementary video stream is done by
