Automate remux and remove junk from avi files

[jorb]

Trying to use avi files on a popcorn hour I discovered playback problems. The solution is that the avi's need to be remuxed and the junk removed from the header. I've tried this and it works. I used AVI-Mux GUI as recommended by the person that helped me out.

However I now have a new problem. I have to do this to several hundred files and doing it via a GUI is going to be painful - the tool I used does not seem to have any automation functions. Can anyone recommend a tool that will perform these functions to a large number of files at a time, or will accept command line parameters so I can write a batch script to do this.

Am a relative newbie at this, so don't assume I know anything.

AVI-Mux GUI does have a command-line interface. There's also MMCL, the Mpeg4modifier command line tool which you can use for unpacking packed bitstream divx files and/or changing the PAR/DAR and FourCC in the header.

The following is an extract from a windows batch script that creates an AMG script for input to AVI-Mux GUI:

echo CLEAR>"%AMG_FILE%"
echo LOAD %VIDEO_FILE%>>"%AMG_FILE%"
echo LOAD %AUDIO_FILE%>>"%AMG_FILE%"
echo SELECT FILE ^1>>"%AMG_FILE%"
echo ADD VIDEOSOURCE>>"%AMG_FILE%"
echo SET OUTPUT OPTIONS>>"%AMG_FILE%"
echo WITH SET OPTION>>"%AMG_FILE%"
echo OVERWRITEDLG ^0>>"%AMG_FILE%"
echo CLOSEAPP ^1>>"%AMG_FILE%"
echo DONEDLG ^0>>"%AMG_FILE%"
echo MAXFILES OFF>>"%AMG_FILE%"
echo STDOUTPUTFMT AVI>>"%AMG_FILE%"
echo AVI ADDJUNKBEFOREHEADERS ^0>>"%AMG_FILE%"
echo AUDIO INTERLEAVE 4 FR>>"%AMG_FILE%"
echo PRELOAD 20^0>>"%AMG_FILE%"
echo AVI HAALIMODE ^0>>"%AMG_FILE%"
echo OPENDML ^0>>"%AMG_FILE%"
echo LEGACY ^0>>"%AMG_FILE%"
echo RECLISTS ^0>>"%AMG_FILE%"
echo END WITH>>"%AMG_FILE%"
echo START %DST_FILE%>>"%AMG_FILE%"

(Thanks to celtic druid at doom9 for the original script on which this is based)
%AMG_FILE% holds the name of the amg script file (i.e. set AMG_FILE=c:\temp\myscript.amg)
%VIDEO_FILE% holds the name of the video source
%AUDIO_FILE% holds the name of the audio source
%DST_FILE% holds the name of the destination avi file
You can run the script by simply calling AVI-Mux GUI with the name of the script as an argument:
AVIMux_GUI.exe c:\temp\myscript.amg
With your situation you will probably want to modify the script a little since your audio and video source will be taken from the same file; google is your best source for this as I haven't found any definitive documentation as yet.

If you want some pointers with windows batch file processing you might want to check out my batch xvid conversion script.
