.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.
