- libspeexdec: decode one frame at a time. · 7eeaa679
  Justin Ruggles authored Oct 21, 2011
```
This allows for knowing the output size before decoding even when there is no
header (e.g. FLV). Otherwise we would have to do a preliminary full frame
decode to determine the number of frames-per-packet.

- vp8: fix up handling of segmentation_maps in reference frames. · ce42a048
  Ronald S. Bultje authored Oct 18, 2011
```
Associate segmentation_map[] with reference frame, rather than
decoding instance. This fixes cases where the map would be free()'ed
on e.g. a size change in one thread, whereas the other thread was
still accessing it. Also, it fixes cases where threads overwrite data
that is still being referenced by the previous thread, who thinks that
it's part of the frame previously decoded by the next thread.

ever used it.
