libxvid video codec leaks temporary files

[Jean Delvare]

When encoding with -vcodec libxvid in two-pass mode, the second pass creates a copy of the first-pass log as /tmp/xvidff.*. This copy is not deleted when the second-pass encoding ends.

I don't know what sense it makes to create a copy of the file in the first place, but assuming there is a good reason for that, this temporary file should be deleted by ffmpeg before it quits. I happen to have /tmp mounted in memory (tmpfs) so every file left behind is actually stealing my memory until next reboot.
