Old Codec processing?

[Phantom_E]

I have some old .AVI video clips that a friend took for me years ago.
The last time I played them I was running Windows NT. The file date is 4/2003, but may be older.

Binary edit of the file shows data organized in blocks with text in the block headers referencing Quicktime and JPEG decompresion.
There seems to be a valid jpeg type 4cc code of JFIF at offset x'0ADD' not the offset x'00BC' where something like AVIC.exe wants to put the codec type.
GSpot will not recognize this file either.

Here is the first 16 bytes if it helps.
The .MOV files I have seem to have 'skip' where the BOBO is.
This one has a .AVI extension, but other avi files seem to start with 'RIFF'.
06 07 AC 00 42 4F 42 4F 06 07 AC 00 00 00 00 00 ....BOBO........

Any ideas on what might use to read this file?

Despite the header comment I think it used to play in WMP. :confused:
TIA

Sounds like you got MJPEG in your avi. If you google around you can download a free mjpeg decoder (or use ffdshow).

Yeah, if you are missing codecs, you might as well get ffdshow.

Thanks for the suggestion.
I downloaded ffdshow.
It shows up in GSpot list of filters and codecs.
Doesn't seem to help.

Best I can figure out ffdshow is some sort of generic mpeg codec.

The problem is nothing I've tried will recognize this BOBO container.
It is not a standard AVI RIFF container or Quicktime container (although it vaguely resembles Quicktime).
Thus things never get to the point where a codec can be selected.
Or at least that's what I'm thinking.

GSpot reports
Container
File Type unknown
Mime Type Unknown.

Hi!I have some old .AVI video clips that a friend took for me years ago...Binary edit of the file shows data organized in blocks with text in the block headers referencing Quicktime and JPEG decompresion.This makes no sense.

Please be good enough to post the first 30-50 lines of the file (as "Code")...

Probably a form of an Indeo codec ...

They aren't included in a lot of "packs" or defaults now days :(

I was thinking, a lot of files put strings to identify what type they are at the beginning, like JFIF for JPEG, GIF87 or GIF89 for GIF, etc... Maybe your file type is BOBO type. A google search suggests it's files created by ClarisWorks. If it's a word processing document, it could contain embedded JPEG's in it, which would account for your spotting JPEG data in it. Just a possibility.
On the other hand, do you recall what you used to play this back when you received it? And are you certain it was a video file?

If it's a mjpeg file or just a bunch of jpg files stored in whatever container you can try my little tool mjpeg2jpg (http://www.geocities.com/hanfrunz/mjpeg2jpg03.zip) (see this old thread (http://forum.doom9.org/showthread.php?t=108253)). I will search for jpg files and extract them.
