[vorbis-dev] ov_time_seek

[Firelight Multimedia]

yes.. 0xCD i think you mean.. when it frees the memory it writes 0xDD in the
previous space .. handy to find corruption..
its like something isnt allocated.
i thought i had something to show you then the bug moves from funcion to
functtion every time i run it .. once it even didnt crash and kept running!
:)

heres what i got once , then the crashed moved somewhere completely
different

in floor0_inverse

- info 0x00f923b0
  |-order 0x0000001e
  |- rate 0x0000ac44
  |- barkmap 0x00000100
  |- ampbits 0x0000000c
  |- ampdB 0x00000096
  |- numbooks 0x00000001
  |- books 0x00f923c8
     |- [0] 0x00000001
     |- [1] 0xcdcdcdcd
     |- [2] 0xcdcdcdcd
     |- [3] 0xcdcdcdcd
     |- [4] 0xcdcdcdcd
     |- [5] 0xcdcdcdcd
- booknum 0x00000001

codebook *b=vb->vd->fullbooks+info->books[booknum];
so
b = vb->vd->fullbooks + 0xcdcdcdcd (zoink)

according to that books has been allocated ok, but only member 0 has
something useful put in it .

The seek seems to work .. i can hear like 100ms or whatever worth of the new
data looping before it crashes.. the read just screws up after it.
everything else working fine btw.

Brett.
