If ommited, \fIstdin\fP is assumed. +.br +.IP "\fB-x \fIcodec\fP" +Process only packets containing given +.I codec +as payload. +Examples are "mpeg2" for MPEG video or "ac3" for audio packets. +.br +.IP "\fB-t \fImagic\fP" +Specify the input file type +.I magic. +Useful for using +.B tcdemux +in pipelines. This is normally autodetected. +.br +.IP "\fB-a \fIach[,vch]\fP" +Process only packets containing given audio track +.I ach +and video track +.I vch. +Most program stream feature multiple audio tracks but only a single video stream. Default is "-a 0,0". +.br +.IP "\fB-s \fI0xnn\fP" +Select specific multimedia track using the standard identifier +.I 0xnn. +This useful to extract subtitle packets. +.br +.IP "\fB-f \fIfps\fP" +Specify the frame rate +.I fps +for subtitle meta information used by external applications. +.br +.IP "\fB-S \fIunit[,s1-s2]\fP" +Select a program unit +.I unit +and a selected GOP range +.I s1-s2 +for processing. A +.I 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 presentation 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. +.br +.IP "\fB-O" +Do not skip initial sequence. Used internally by transcode. +.br +.IP "\fB-A \fIn[,m[,...]]\fP" +Select packets using an identifier for extracting only selected streams without processing. This is useful for size reduction of your multimedia stream. Example: + +.B tcdemux -i big_dvd.vob -A 0xe0,0x81,0x20 > small_dvd.vob + +extracts all packets for the video stream, AC3 audio track (1) and the +first subtitle stream (0). +.br +.IP "\fB-M \fImode\fP" +Select synchronization strategy +.I 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 \fIstdout\fP. + +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 \fIstdout\fP 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 transcode. + +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. +.br +.IP "\fB-P \fIfile\fP" +Write GOP meta information to +.I file +instead of \fstdout\fP. +.br +.IP \fB-W +Print a navigation log file for a given video stream to \fIstdout\fP. This is used for transcode's "psu mode" and "cluster mode". +.br +.IP "\fB-d\fP \fIlevel\fP" +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 +.IP "\fB-v\fP" +Print version information and exit. +.SH NOTES +\fBtcdemux\fP is a front end for de-multiplexing program streams and is used in \fBtranscode\fP's import modules. +.SH EXAMPLES +The command + +.B tcprobe -i movie.vob -x mpeg2 + +extracts only MPEG video packets.
