>I got the table size from Rockbox. I don't know where they got it.
Trial and error. Originally I picked started at 0, then -16 and?finally -60. ?
There are no known samples where this overflows. I didn't originallysubmit that patch back to ffmpeg because I wanted to be sure. Its beenover a year now and not a single bug report concerning that change,so I think its quite safe for all intact files. I don't know ifbroken files could take other values or not.
