corrupted AVIs > 1GB in size with mencoder with versions after pre3

[SSci@…]

This happens with pre4, pre5 and cvs versions of mplayer, and makes them
unusable for me.

When the avi size increases over 1GB everything seems to work, but I'm unable to
play the file after that 1GB boundary. This is not mplayer related problem,
since I can't play it back with xine either nor can I split it with aviplit.
Aviplit gives be 700MB and 300MB+ files (original 1.4GB)

However with pre3 release (from gentoo portage), it is working as it should be.
Therefore I doubt that the problem is related to particularily my box. Here's
the system info anyways.

Please upload such a file to mphq and also did you try to playback the file
on a 32 bit machine?
I guess the problem is somewhere in the struct packing.

[SSci@…]

I don't have a 32 bit machine and I don't have the files anymore. But I'll try
to reproduce it.

This seems related and he's not on amd64:

Tried to remux an ok avi, with mencodercvs, and it shows that the lenght is
1:09:40, but the original is 1:38:00. It seems to play ok, but it plays longer
than it says the avi should be.

Then I remuxed this broken one with pre3 and it is again 1:38:00 in lenght.

This doesn't seem to be exactly the same thing, because the file stays playable,
but I'm sure it is related to the original problem. I guess I need to encode
something to reproduce this.
