NAME

       esfilter - Output a filtered or truncated version of a ES

SYNOPSIS

       esfilter [actions/switches] <infile> <outfile>

DESCRIPTION

	      TS tools version 1.11, esfilter built Nov 11 2008 17:15:39

	      Output a filtered or truncated version of an elementary stream.  The input is either H.264 (MPEG-4/AVC) or H.262 (MPEG-2).  The out-
	      put is either an elementary stream, or an H.222 transport stream

	      If output is to an H.222 Transport Stream, then fixed values for the PMT PID (0x66) and video PID (0x68) are used.

   Files:
       <infile>
	      is the input elementary stream (but see -stdin below).

	      <outfile> is the output stream, either an equivalent elementary

	      stream, or an H.222 Transport Stream (but see -stdout and -host below).

   Actions:
       -copy  Copy the input data to the output file (mostly useful as a way of truncating data with -max)

       -filter
	      Filter data from input to output, aiming to keep every <n>th frame (where <n> is specified by -freq).

       -strip For H.264, output just the IDR and I pictures, for H.262, output just the I pictures, but see -allref below.

   Switches:
       -verbose, -v
	      Output extra (debugging) messages

       -quiet, -q
	      Only output error messages

       -stdin Take input from <stdin>, instead of a named file

       -stdout
	      Write output to <stdout>, instead of a named file Forces -quiet.

       -host <host>, -host <host>:<port>
	      Writes output (over TCP/IP) to the named <host>, instead of to a named file. If <port> is not specified, it defaults to 88.  Implies
	      -tsout.

       -max <n>, -m <n>
	      Maximum number of frames to read (for -filter and -strip), or ES units/NAL units (for -copy).

       -freq <n>
	      Specify the frequency of frames to try to keep with -filter. Defaults to 8.

       -allref
	      With -strip, keep all reference pictures (H.264) or all I and P pictures (H.262)

       -tsout Output data as Transport Stream PES packets (the default is as Elementary Stream)

       -pes, -ts
	      The input file is TS or PS, to be read via the PES->ES reading mechanisms. Not allowed with -stdin.

   Stream type:
	      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 or H.262 data. This
	      process may occasionally come to the wrong conclusion, in which case the user can override the choice using the following switches.

	      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.

       -h264, -avc
	      Force the program to treat the input as MPEG-4/AVC.

       -h262  Force the program to treat the input as MPEG-2.
