" stream. If the program stream data contains more than one of each,\n"
" the first will be used, and the others ignored (with a message\n"
" indicating this).\n"
"\n"
" It is assumed that the video stream will contain DTS values in its\n"
" PES packets at reasonable intervals, which can be used as PCR values\n"
" in the transport stream, and thus the video stream's PID can be used\n"
" as the PCR PID in the transport stream.\n"
"\n"
"Files:\n"
" <infile> is a file containing the program stream data\n"
" (but see -stdin below)\n"
" <outfile> is a transport stream file\n"
" (but see -stdout and -host below)\n"
"\n"
"Input switches:\n"
" -stdin Take input from <stdin>, instead of a named file\n"
" -dvd The PS data is from a DVD. This is the default.\n"
" This switch has no effect on MPEG-1 PS data.\n"
" -notdvd, -nodvd The PS data is not from a DVD.\n"
" The DVD specification stores AC-3 (Dolby), DTS and\n"
" other audio in a specialised manner in private_stream_1.\n"
" -vstream <n> Take video from video stream <n> (0..7).\n"
" The default is the first video stream found.\n"
" -astream <n> Take audio from audio stream <n> (0..31).\n"
" The default is the first audio stream found\n"
" (this includes private_stream_1 on non-DVD streams).\n"
" -ac3stream <n> Take audio from AC3 substream <n> (0..7), from\n"

"\n"
"Output switches:\n"
" -err stdout Write error messages to standard output (the default)\n"
" -err stderr Write error messages to standard error (Unix traditional)\n"
" -stdout Write output to <stdout>, instead of a named file\n"
" Forces -quiet and -err stderr.\n"
" -host <host>, -host <host>:<port>\n"
" Writes output (over TCP/IP) to the named <host>,\n"
" instead of to a named file. If <port> is not\n"
" specified, it defaults to 88.\n"
" -vpid <pid> <pid> is the video PID to use for the data.\n"
" Use '-vpid 0x<pid>' to specify a hex value.\n"
" Defaults to 0x68.\n"
" -apid <pid> <pid> is the audio PID to use for the data.\n"
" Use '-apid 0x<pid>' to specify a hex value.\n"
" Defaults to 0x67.\n"
" -noaudio Don't output the audio data\n"
" -pmt <pid> <pid> is the PMT PID to use.\n"
" Use '-pmt 0x<pid>' to specify a hex value.\n"
" Defaults to 0x66\n"
" -prepeat <n> Output the program data (PAT/PMT) after every <n>\n"
" PS packs. Defaults to 100.\n"
" -pad <n> Pad the start with <n> filler TS packets, to allow\n"
" a TS reader to synchronize with the datastream.\n"
" Defaults to 8.\n"
"\n"
"General switches:\n"
" -verbose, -v Print a 'v' for each video packet and an 'a' for \n"

" -quiet, -q Only output error messages\n"
" -max <n>, -m <n> Maximum number of PS packs to read\n"

"Stream type:\n"
" When the TS data is being output, it is flagged to indicate whether\n"
" it conforms to H.262, H.264, etc. It is important to get this right, as\n"
" it will affect interpretation of the TS data.\n"
"\n"
" If input is from a file, then the program will look at the start of\n"
" the file to determine if the stream is H.264 or H.262 data. This\n"
" process may occasionally come to the wrong conclusion, in which case\n"
" the user can override the choice using the following switches.\n"
"\n"
" If input is from standard input (via -stdin), then it is not possible\n"
" for the program to make its own decision on the input stream type.\n"
" Instead, it defaults to H.262, and relies on the user indicating if\n"
" this is wrong.\n"
"\n"
" -h264, -avc Force the program to treat the input as MPEG-4/AVC.\n"
" -h262 Force the program to treat the input as MPEG-2.\n"
" -mp42 Force the program to treat the input as MPEG-4/Part 2.\n"
" -vtype <type> Force the program to treat the input as video of\n"
" stream type <type> (e.g., 0x42 means AVS video). It is\n"
" up to the user to specify a valid <type>.\n"
"\n"
" If the audio stream being output is Dolby (AC-3), then the stream type\n"
" used to output it differs for DVB (European) and ATSC (USA) data. It\n"
" may be specified as follows:\n"
