.SH NAME
iso13818ps \- multiplexer for ISO 13818 program streams
.SH SYNOPSIS
iso13818ps [COMMAND...]
.SH DESCRIPTION
Generates an ISO 13818-1 conforming program stream from multiple
input streams.
The result is sent to \fIstdout\fR,
the input streams are read from explicitely opened files.
All of the following commands may also be fed to \fIstdin\fR during
operation by omitting the leading hyphen (e.g. \fBQ\fR) or
double-hyphen (e.g. \fBquit\fR).
.TP
\fB\-\-help\fR
Display this help.
.TP
\fB\-V\fR, \fB\-\-version\fR
Output version information.
.TP
\fB\-Q\fR, \fB\-\-quit\fR
Quit this program.
.TP
\fB\-v\fR, \fB\-\-verbose\fR [\fIlevel\fR]
Verbose mode, \fIlevel\fR = 0..6, default is 2 (providing warnings
concerning data errors), initial verbosity is 1 (providing only
program errors).
.TP
\fB\-p\fR, \fB\-\-pes\fR \fIfile\fR
Open a PES input \fIfile\fR,
output the contained stream.
.TP
\fB\-p\fR, \fB\-\-pes\fR \fIfile\fR \fItarget_stream_id\fR
Open a PES input \fIfile\fR,
output the contained stream
with \fItarget_stream_id\fR (recommended range 0xBD..0xFE).
The \fIfile\fR may be specified as \fB=\fR to denote
the last previously mentioned file.
.TP
\fB\-P\fR, \fB\-\-ps\fR \fIfile\fR
Open a PS input \fIfile\fR,
output the contained program.
.TP
\fB\-P\fR, \fB\-\-ps\fR \fIfile\fR \fIsource_stream_id\fR [\fItarget_stream_id\fR]
Open a PS input \fIfile\fR,
extract the stream with \fIsource_stream_id\fR (range 0x00..0xFF)
and output that stream
with \fItarget_stream_id\fR (recommended range 0xBD..0xFE).
If no \fItarget_stream_id\fR is given, \fIsource_stream_id\fR is used instead.
The \fIfile\fR may be specified as \fB=\fR to denote
the last previously mentioned file.
.TP
\fB\-T\fR, \fB\-\-ts\fR \fIfile\fR
Open a TS input \fIfile\fR,
extract all programs from it and output them.
.TP
\fB\-T\fR, \fB\-\-ts\fR \fIfile\fR \fIsource_program\fR
Open a TS input \fIfile\fR,
extract the program \fIsource_program\fR (range 0x0001..0xFFFF)
and output that program.
The \fIfile\fR may be specified as \fB=\fR to denote
the last previously mentioned file.
.TP
\fB\-T\fR, \fB\-\-ts\fR \fIfile\fR \fIsource_program\fR \fIsource_stream_id\fR [\fItarget_stream_id\fR]
Open a TS input \fIfile\fR,
extract the stream with \fIsource_stream_id\fR (range 0x00..0xFF)
from the program \fIsource_program\fR (range 0x0001..0xFFFF)
and output that stream as \fItarget_stream_id\fR (recommended range 0xBD..0xFE)
.
If no \fItarget_stream_id\fR is given, use \fIsource_stream_id\fR instead.
The \fIfile\fR may be specified as \fB=\fR to denote
the last previously mentioned file.
.TP
\fB\-T\fR, \fB\-\-ts\fR \fIfile\fR 0 \fIsource_stream_id\fR [\fItarget_stream_id\fR]
As before, but extract a stream with \fIsource_stream_id\fR (range 0x00..0xFF)
from a transport stream with broken or missing PAT/PMT information.
The stream is opened only, if there is \fBnot\fR any entry in the
tables for that stream.
Note, that if there is more than one stream with the given
\fIsource_stream_id\fR,
only one matching stream will be opened, and
the choice is not deterministic.
.TP
\fB\-c\fR, \fB\-\-close\fR \fIfile\fR
Close input \fIfile\fR, as if eof is reached.
In combination with \fB\-\-repeat\fR this causes the next repeatition
to start immediately.
Note, that the input data file is cut of as is, i.e. no attempt
is made to close the file on a clean audio or video frame boundary.
.TP
\fB\-a\fR, \fB\-\-append\fR \fIfile1\fR \fIfile2\fR [\fInum\fR]
Earmark another \fIfile2\fR to be opened as soon as \fIfile1\fR
comes to its end.
The appended \fIfile2\fR is foreseen to be repeated \fInum\fR
times, default is 1 (see \fB\-\-repeat\fR).
Both files must contain the same type of data,
as the data of both files is chained without considering clean
transition of audio or video sequences.
The \fIfile1\fR may be specified as \fB=\fR to denote
the last previously mentioned file.
.TP
\fB\-f\fR, \fB\-\-file\fR \fIreference_number\fR \fIfile_name\fR
The positive \fIreference_number\fR is associated with a \fIfile_name\fR.
For all following commands, the \fIreference_number\fR may be
used instead of the \fIfile_name\fR. This allows better control
over file handles, as the same file may be addressed via different
\fIreference_number\fRs.
.TP
\fB\-x\fR, \fB\-\-crop\fR [\fItarget_stream_id\fR]
Delete a stream given by \fItarget_stream_id\fR,
or the complete program
from the output.
The corresponding input file(s) will be closed, if not needed otherwise.
.TP
\fB\-r\fR, \fB\-\-repeat\fR \fIfile\fR \fInum\fR
Set the repeatition counter for \fIfile\fR to \fInum\fR
(or to infinite if \fInum\fR=0).
The file will be reset as soon as eof is reached
(or it is closed by the command \fB\-\-close\fR).
Note, that the file will be reset without considering clean transition
of audio or video sequences at the restart point.
The \fIfile\fR may be specified as \fB=\fR to denote
the last previously mentioned file.
.TP
\fB\-R\fR, \fB\-\-reopen\fR
This command shall precede one of the commands that open a new file
(i.e. \fB\-\-pes\fR, \fB\-\-ps\fR or \fB\-\-ts\fR must follow
\fIon the same line\fR).
The next file will be opened with a new file handle,
regardless of whether the same file is yet open or not.
.TP
\fB\-\-descr\fR [\fIdescr_tag\fR [\fIdescr_length\fR \fIdata\fR...]]
Add, inhibit or delete in the PMT section a descriptor,
that does \fBnot\fR belong to a specific stream.
To add a descriptor, all parameters must be given,
\fIdescr_tag\fR (range 0x00..0xFF),
\fIdescr_length\fR (range 1..255),
and the appropriate amount of bytes given as \fIdata\fR (range 0x00..0xFF).
To inhibit any descriptor with a given \fIdescr_tag\fR,
\fIdescr_length\fR is set to \fB0\fR and no \fIdata\fR is given.
This causes matching descriptors from input streams to
be discarded instead of being copied to the target stream.
To delete the manual setting of a descriptor,
\fIdescr_length\fR is omitted. This causes descriptors
with matching \fIdescr_tag\fR to be passed from input to
the target stream.
To delete all manual settings,
that do \fBnot\fR belong to a specific stream,
the \fIdescr_tag\fR is omitted, too.
Note, that \fB\-\-descr\fR never modifies descriptors,
that belong to a specific stream.
To modify these, use the command \fB\-\-sdescr\fR.
.TP
\fB\-\-sdescr\fR [\fIstream_id\fR [\fIdescr_tag\fR [\fIdescr_length\fR \fIdata\fR...]]]
Add, inhibit or delete in the PMT section a descriptor,
that does belong to a specific stream.
To add a descriptor, all parameters must be given,
\fIstream_id\fR (recommended range 0xBD..0xFE),
\fIdescr_tag\fR (range 0x00..0xFF),
\fIdescr_length\fR (range 1..255),
and the appropriate amount of bytes given as \fIdata\fR (range 0x00..0xFF).
To inhibit any descriptor with a given \fIdescr_tag\fR,
\fIdescr_length\fR is set to \fB0\fR and no \fIdata\fR is given.
This causes matching descriptors from the corresponding input streams to
be discarded instead of being copied to the target stream.
To delete the manual setting of a descriptor,
\fIdescr_length\fR is omitted. This causes descriptors
with matching \fIdescr_tag\fR to be passed from input to
the target stream.
To delete all manual settings for a \fIstream_id\fR,
the \fIdescr_tag\fR is omitted, too.
To delete all manual settings for all streams \fBand\fR those
that do not belong to a specific stream,
the \fIstream_id\fR is omitted, too.
.TP
\fB\-B\fR, \fB\-\-busy\fR [\fInum\fR]
Set the busy flag to \fInum\fR (range 0..1, default is 1).
Whenever the program has no more data to handle and
the busy flag is not set, it stops.
.TP
\fB\-\-timed\fR
Force delay timing, even if solely disk files are in use.
If not so, if delay is to be awaited while processing regular files,
the delay is skipped instead and timing information in the resulting
file is adjusted accordingly.
.TP
\fB\-F\fR, \fB\-\-fpsi\fR \fItime\fR
Set the PSI table frequency to \fItime\fR msec
(or to infinite if \fItime\fR=0, initial value is infinite).
The PAT and PMT will be generated at more or less the given
frequency, even if the tables did not change.
In any case, the next tables will be generated immediately.
.TP
\fB\-\-trigin\fR \fItime\fR
Set the input buffer trigger timing to \fItime\fR.
For any input stream, that is newly opened
(or has to be retriggered, e.g. due to intermediate emptiness),
the buffer is triggered for promotion to the splice unit
with a delay of \fItime\fR msec compared to the time
of data entrance into the buffer.
For any stream yet triggered the timing is not changed
unless retriggering takes place.
Not affected by this value are the other trigger conditions,
mainly a certain buffer fullness
and cotriggering with a corresponding stream that is triggered.
.TP
\fB\-\-trigout\fR \fItime\fR
Set the output buffer trigger timing to \fItime\fR.
As the output buffer is triggered for promotion to \fIstdout\fR,
this is done with a delay of \fItime\fR msec compared to the time
of data entrance into the buffer.
The new timing is only valid if set before the first triggering
of the output buffer,
or if retriggering takes place, e.g. due to intermediate emptiness.
Not affected by this value is the trigger condition
of a certain buffer fullness.
.TP
\fB\-C\fR, \fB\-\-config\fR \fInum\fR
Order output configuration of target stream with \fInum\fR=1,
switch off with \fInum\fR=0.
Set \fInum\fR=2, to get information about descriptors, too.
