NAME
       stream_type - attempt to determine if an input stream is TS, PS, or ES

SYNOPSIS
       stream_type [switches] <infile>

DESCRIPTION
	      TS tools version 1.11, stream_type built Nov 11 2008 17:15:48

	      Attempt to determine if an input stream is Transport Stream, Program Stream, or Elementary Stream, and if the latter, if it is H.262
	      or H.264 (i.e., MPEG-2 or MPEG-4/AVC respectively).  The mechanisms used are fairly crude, assuming that: - data is byte	aligned  -
	      for TS, the first byte in the file will be the start of a NAL unit,

	      and PAT/PMT packets will be findable

	      - for PS, the first packet starts immediately at the start of the

	      file, and is a pack header

	      - if the first 1000 packets could be H.262 *or* H.264, then the data

	      is  assumed to be H.264 (the program doesn't try to determine sensible sequences of H.262/H.264 packets, so this is a reasonable way
	      of guessing)

	      It is quite possible that data which is not relevant will be misidentified

	      The program exit value is: *  10 if it detects Transport Stream, *  11 if it detects Program Stream, *  12 if it detects	Elementary
	      Stream  containing  H.262  (MPEG-2),  *	14 if it detects Elementary Stream containing H.264 (MPEG-4/AVC), *  5 if it looks like it
	      might be PES, *  9 if it really cannot decide, or *  0 if some error occurred

   Files:
       <infile>
	      is the file to analyse

   Switches:
       -verbose, -v
	      Output more detailed information about how it is making its decision

       -quiet, -q
	      Only output error messages
