Free AVI tools: AVIDiag utility - performs avi sub-system health check

AVIDiag is an utility that allows you to get an additional information about your system, related to video capture, editing and playback. You may need it before you contact AM Software customer support team. Of course you can use AVIDiag for your own needs at no charge, when you solve your problem, excluding the business environment. In other words, you shouldn't offer an ad-ware (or other non-free) online help desk based on AVIDiag's check results.

AVIDiag tests some system capabilities and generates a report that can be written to a text file. Also AVIDiag creates a file dump (in general, an avi file dump) and recognises few common codecs. This allows you to avoid sending huge avi files by e-mail to the support team - just send a dump file instead.

When you need it

  • Got a Cannot find VIDS:MJPG decompressor. message (there can be reported something other instead of 'MJPG')
  • After a 60%..80% of saving to new file you got Cannot read file. message
  • You can hear the sound but see no picture on playback
  • Edited a file previous week, but today AVIedit does not see it
  • Lost a codec
  • Finished hardware upgrade - now some clips have no picture
  • Recovered or reinstalled OS clean - but mediaplayer fails to play movies
How to use it

Just run it and hit Go! button, wait a few seconds. You will get log window filled with text. Save it to a file and examine it with your own eyes, or attach the file when writing an e-mail to us.

If AVIDiag hangs for some reason, (we never seen it screwed up, but we didn't run it on your system...), you may need to switch off some tests. We assume, when you clear some check box, you know what you're doing. If you skipped few tests, please mention this fact when writing us.

To see the suspicious avi file header dump, load the file using menu or Open icon. Also (if the codec is known to AVIDiag) there will be a short string that describes the codec used to create (compress) the file. This is important because you couldn't play avi file without an appropriate codec installed.

After you performed the tests, it is time to save log to a text file. It would be a good idea to save and compare these logs each time you install and/or remove any video related software. This will put you in control over the system.

Of course, it is not necessary to attach the generated log files each time you contact AM Software. However we highly suggest you to run this diagnostic software - just because you could read the report and could detect some problems even without our help, even before you send e-mail to us. This definitely will save your time and, probably, will make our support team life a bit easier :)

At least, the information gathered by AVIDiag will help us to help you.

It covers these sections:

  • system.ini list of descriptions, list of 16 and 32 bit codecs
  • load DLL test tries to load all the codecs listed in [drivers32]
  • capture drivers (VfW) enumerates all VfW capture drivers known to the system
  • Registry - AVIFile reports most important GUIDs related to AVI
  • Registry - Uninstall list of current software that could be uninstalled via Control Panel
AVIDiag 1.2 has few improvements over the previous build.
  • win2k/NT option allows you to verify list of codecs, that is not visible in [drivers32] section of system.ini file
  • mfc42.dll test lists all important dll's common to the system
  • pending dll's reports the state of misc dll's that may be envolved into running AVIedit or other video editing software
