[Mplayer-users] [mplayer PATCH] fastmemcpy SSE support

Hi,

Ok.

In the files. :)
Try with the -bps option, it will forces sync method used by seeking.
By default, A-V sync is made similar to mpeg files, using PTS values (but
they are somehow dummy for AVI files, since AVI has no PTS). In most cases
it works better than 'official' avi timing, except for some files.

It's a bug, I'll fix it. Thanks.
