       avimerge	- merge	several	AVI-files into one

       avimerge	-o name	-i file1 [ file2 [ ... ] ] [ -p	file ] [ -a num	] [ -A
       num ] [ -b num ]	[ -c ] [ -f commentfile	] [ -x indexfile ]

       avimerge	is Copyright (C) by Thomas Oestreich.

       avimerge	is a  versatile	tool.  It can contatenate several AVI files
       into one. It can	also be	used to	fix an index of	a broken file and can
       also replace audio tracks or muxes new ones. It can read	raw AC3	and
       MP3 files for multplexing.

       -o name
	      Specify the name of the output file.

       -i file
	      Specify the name(s) of the input file(s) to merge	into the out-
	      put file.

       -p file
	      Specify the name of the audio file to multiplex into the output
	      file. The	type of	file can be either another AVI file or an MP3
	      or AC3 file.

       -b num Specify if avimerge should write an VBR mp3 header into the AVI
	      file. Default is dependent on the	input file (and	usually	cor-
	      rect). num is either 1 or	0.

       -c     Drop video frames	in case	audio is missing [off]
	      Only when	merging	multiple AVI files. Some AVI files run a lit-
	      tle bit (usually for one or two video frames) short on audio.
	      This means avimerge cannot keep up sync when concatinating them.
	      The files	play fine when played individually but not when	merged
	      because audio from the new file gets played back with video from
	      the old file.  avimerge will print a message like

		No audiodata left for track 0->0 (59950.25=59950.25) continuing	..

	      When you turn on the -c option, the video	which is too much will
	      be dropped.

       -f commentfile
	      Read AVI tombstone data for header comments from commentfile.
	      See /docs/avi_comments.txt for a sample.

       -x indexfile
	      Read the AVI index from indexfile.  See aviindex(1) for informa-
	      tion on how to create such a file.

       -a num Specify the number of the	audio track you	want to	use from the
	      input file.

       -A num Specify the number of the	audio track you	want to	use in the
	      output file. If you specify an existing track number, the	track
	      will be replaced.	If omitted, the	next free slot will be used.

       The command

       avimerge	-o big.avi -i my_file1.avi my_file2.avi	my_file3.avi

       merges the three	input files my_file[123].avi into one big AVI-file

       avimerge	-o out.avi -i in.avi -p	audio2.avi -a 1

       merges track number 1 form in.avi to the	next free track	number in
       out.avi.	You can	create audio-only AVI-files using

       transcode -i song.mp3 -x	null,mp3 -g 0x0	-y raw -a 1 -o audio2.avi -u 50

       The command

       avimerge	-o out.avi -i in.avi -p	sound.mp3

       merges the file sound.mp3 as an additional audio	track into out.avi.
