NAME

     esreport — Report on the contents of an ES

SYNOPSIS

     esmerge [-err stdout] [-err stderr] [-verbose | -v] [-quiet | -q]
             [-frames | -findfields | -afd | -es] [-framesize] [-frametype] [-x]
             [-max max-units | -m max_units] [-pes | -ts] [-pesreport]
             [-h264 | -avc | -h262 | -avs] in_file | -stdin

DESCRIPTION

     Report on the content of an elementary stream containing H.264 (MPEG-4/AVC), H.262 (MPEG-2)
     or AVS video data.

   Files
     in_file
             is the Elementary Stream file (but see -stdin below)

   What to report
     The default is to report on H.262 items, AVS frames or H.264 NAL units.  Other choices are:

     -frames
             Report by frames. The default for AVS.

     -findfields
             Report on any fields in the data. Ignored for AVS.

     -afd    Report (just) on AFD changes in H.262. Ignored for the other types of file.

     -es     Report on ES units.

     Reporting on frames may be modified by:

     -framesize
             Report on the sizes of frames (mean, etc.).

     -frametype
             Report on the numbers of different type of frame.

     (in fact, both of these imply -frame).

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

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

     -stdin  Input from standard input, instead of a file

     -v, -verbose
             For H.262 data, output information about the data in each MPEG-2 item. For ES units,
             output information about the data in each ES unit. Ignored for H.264 data.

     -q, -quiet
             Only output summary information (i.e., the number of entities in the file,
             statistics, etc.)

     -x      Show details of each NAL unit as it is read.

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

     -max max_units, -m max_units
             Maximum number of NAL units/MPEG-2 items/AVS frames/ES units to read. If -frames,
             then the program will stop after that many frames. If reading 'frames', MPEG-2 and
             AVS will also count sequence headers and sequence end.

     -pes, -ts
             The input file is TS or PS, to be read via the PES to ES reading mechanisms

     -pesreport
             Report on PES headers. Implies -pes and -q.

   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, H.262 or AVS 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.

     -avs    Force the program to treat the input as AVS.
