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.
