Error playing DVD titles which start at position over 2GB

[vklimk@…]

Hi,

This bug affects mplayer and mencoder.
How to reproduce it:

• You need to have dvd with multiple chapters. One (or many) of them have to start at position over 2GB.
• Start to play/grab such title (mplayer dvd://18 -dvd-device u:)
• Playing will start in some minutes only and not from the beginning of the title

When I tried to find out the reason of this error I enabled verbose output (-v -v -v) and compare output for good case (title starts under 2GB) and for bad one
(title started over 2GB). Look at it, please:

### CELL 0: Navi: 1/1 IFO: 1/18

You can see that for bad case there if integer overflow somewhere:

newpos=FFFFFFFF831A7000 new_bufpos=FFFFFFFF831A7000

Hope this information will help you to debug and fix this error. I can send full output if you need it.

Thanks,
Viktor

Possibly caused by miscompilation which lacks large file support?

[vklimk@…]

I use mplayer and mencoder compiled for windows (version 1.0rc1). I downloaded it from official mplayer site.
It will be great if you fix this issue.

Thanks,
Viktor
