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.
