View Full Version : lowercase "xvid"

I think I saw this before, but I can't remember
what/if there was a solution.

If I play an avi that internally has the 4cc = "xvid"
the file plays, but the xvid filter is not invoked and the avi is
upside down.

If I use a hex editor and change "xvid" to XVID all is normal.

Why isn't the system (diectshow?) not recognizing "xvid"
(lowercase) properly?

Thanks for any info.

Here's how the graph looks when the 4cc is "xvid" - graph-bad.jpg

and here's how it looks normally. (4cc = "XVID")
The only difference between these
two files is the 4cc changed with a hex editor - graph-good.jpg.

Secondly, if you look at this report from gspot,
it looks as if xvid should be handled. - gspot-xvid.jpg

This occurs in Windows Media Player 6.4 and version 9 also.
The video is upside down, xvid is not it the list of filters being used,
as can be seen from the 2nd graph above.
