FourCC: xvid vs. XVID

[jeffy]

Well, I found in some of my older encodes the fourCC "xvid" lowercase was used and they refuse to be played in Media Player Classic, Windows Media Player etc. Is there any way BESIDES rewriting the headers with "XVID"? I cannot correct the value vidc.XVID in Windows XP Professional SP2 registry, with vidc.xvid, the OS complain the value exists.

Any other ideas, please? :thanks:

ffdshow can play it

Thank you for your suggestion clsid, do you know about any way how can I force a "normal" (standard) Xvid codec to decode it?

Use a FourCC change tool.

:rolleyes:, thank you, but I am looking for a method forcing the xvid codec to decode it, not by rewriting headers.

If the reg hack doesn't work, then probably not...

You can hex edit the xvid binary if you're adventurous, or recompile it. :p Using ffdshow would be quite a bit simpler though.

Can you elaborate on the bold part, please? Can I somehow change only the XVID string in the binary to xvid and will it retain both fourCCs (XVID & xvid)?

Regarding the registry hack, does anyone have the one working with both fourCCs?

Thank you to everyone.

-- Well, I still have the last option - ffdshow and Xvid decoder selected. --

One FourCC is for selecting the preferred decoder. The other one is the actually FourCC that is used to identify the type of video in the file.

With Nic's FourCC changer tool you can simply change the FourCC. Very simple and the rest of the file stays exactly the same.

Are your files on read-only media? Otherwise why don't you want to rewrite the header.

As for your registry problem. Delete the value and re-create it. Although I don't think it would make a difference.

Thank you, yes, you guessed it right :).
I have archived some tens of files in that codec onto read-only DVD media and it is a nuisance for me to copy them back and forth just to watch them ;). BTW, was it some fault in earlier xvid versions? I don't remember changing anything at that time.... so the fourCC xvid was written into them automatically.
