Since nnz can be zero, this is needed to avoid a shift by 32.

put_bits: fix invalid shift by 32 in flush_put_bits() · ac6eab14

Mans Rullgard authored Oct 08, 2011

If flush_put_bits() is called when the 32-bit buffer is empty,
e.g. after writing a multiple of 32 bits, and invalid shift by
32 is performed.  Since flush_put_bits() is called infrequently,
this additional check should have negligible performance impact.

wavpack_decode_block() supposes that it is called back with the exact
same buffer unless it has returned with an error. With multi-channels
files, wavpack_decode_frame() was breaking this assumption.

- H264: Only wait before triggering ff_thread_setup_complete() until the next... · 14c21c1f
  Michael Niedermayer authored Oct 03, 2011
```
H264: Only wait before triggering ff_thread_setup_complete() until the next slice that contains a start-of-field/frame macroblock

This allows concurrent decoding of the last field/frame, rather than
only the last slice, of data packets with multiple NAL units packed
together.

This will fix the slowdown reported in e.g. bug 52.
