DESCRIPTION

       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 multplex-
       ing.

OPTIONS

       -o name
	      Specify the name of the output file.

       -i file
	      Specify the name(s) of the input file(s) to merge
	      into the output 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 correct). 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 little 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 sam-
	      ple.

       -x indexfile
	      Read the AVI index from indexfile.  See aviindex(1)
	      for information 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 omit-
	      ted, the next free slot will be used.

EXAMPLES

       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 big.avi.

       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.
