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 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 sample.

       -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 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.
