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
