.Sh DESCRIPTION
|
|
Convert an elementary video stream to H.222 transport stream.
|
|
Supports input streams conforming to MPEG-2 (H.262), MPEG-4/AVC
|
|
(H.264) and AVS. Also supports MPEG-1 input streams, insofar as MPEG-2
|
|
is backwards compatible with MPEG-1.
|
|
.Pp
|
|
Note that this program works by reading and packaging the elementary
|
|
stream packages directly - it does not parse them as H.262 or H.264
|
|
data.
|
|
.Ss Files
|
|
.Bl -tag
|
|
.It Ar in_file
|
|
is a file containing the Elementary Stream data (but see -stdin below)
|
|
.It Ar out_file
|
|
is an H.222 Transport Stream file (but see -stdout and -host below)
|
|
.El
|
|
.Ss Switches
|
|
.Bl -tag
|
|
.It Fl "err stdout"
|
|
Write error messages to standard output (the default)
|
|
.It Fl "err stderr"
|
|
Write error messages to standard error (Unix traditional)
|
|
.It Fl v , Fl verbose
|
|
Output summary information about each ES packet as it is read
|
|
.It Fl q , Fl quiet
|
|
Only output error messages
|
|
.It Fl pid Ar pid_no
|
|
.Ar pid_no
|
|
is the video PID to use for the data.
|
|
Use '-pid 0x<pid>' to specify a hex value.
|
|
.Bq default = 0x68
|
|
.It Fl pmt Ar pmt_pid_no
|
|
.Ar pmt_pid_no
|
|
is the PMT PID to use.
|
|
Use '-pmt 0x<pid>' to specify a hex value.
|
|
.Bq default = 0x66
|
|
.It Fl max Ar max_units , Fl m Ar max_units
|
|
Maximum number of ES data units to read
|
|
.It Fl stdin
|
|
Input from standard input, instead of a file
|
|
.It Fl stdout
|
|
Write output to <stdout>, instead of a named file
|
|
Forces -quiet and -err stderr.
|
|
.It Fl host Ar host Ns Op : Ns Ar port
|
|
Writes output (over TCP/IP) to the named
|
|
.Ar host ,
|
|
instead of to a named file. If
|
|
.Ar port
|
|
is not specified, it defaults to 88.
|
|
.El
|
|
.Ss Stream type
|
|
When the TS data is being output, it is flagged to indicate whether
|
|
it conforms to H.262, H.264 or AVS. It is important to get this right,
|
|
as it will affect interpretation of the TS data.
|
|
.Pp
|
|
If input is from a file, then the program will look at the start of
|
|
the file to determine if the stream is H.264, H.262 or AVS. This
|
|
process may occasionally come to the wrong conclusion, in which case
|
|
the user can override the choice using the following switches.
|
|
.Pp
|
|
If input is from standard input (via -stdin), then it is not possible
|
|
for the program to make its own decision on the input stream type.
|
|
Instead, it defaults to H.262, and relies on the user indicating if
|
|
this is wrong.
|
|
.Bl -tag
|
|
.It Fl h264 , avc
|
|
Force the program to treat the input as MPEG-4/AVC.
|
|
.It Fl h262
|
|
Force the program to treat the input as MPEG-2.
|
|
.It Fl avs
|
|
Force the program to treat the input as AVS.

For the moment, the video input must be H.264 or AVS, and the audio input
|
|
ADTS, AC-3 ATSC or MPEG layer 2. Also, the audio is assumed to have a
|
|
constant number of samples per frame.
