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 multplexing.

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 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.

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.
