NAME

       stream-type — Guess the type of a stream file

SYNOPSIS

       stream-type [-err stdout] [-err stderr] [-verbose | -v] [-quiet | -q] in_file

DESCRIPTION

       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

   Files
       in_file
               is the file to analyse

   Switches
       -err stdout
               Write error messages to standard output (the default)

       -err stderr
               Write error messages to standard error (Unix traditional)

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

       -q, -quiet
               Only output error messages

RETURN VALUES

       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
