Remove unnecessary parameter from ff_thread_init() and fix behavior · ba9ef8d0

thread_count passed to ff_thread_init() is only used to set AVCodecContext.
thread_count, and can be removed. Instead move it to the legacy implementation
of avcodec_thread_init().

This also fixes the problem that calling avcodec_thread_init() with pthreads
enabled did not set it since ff1efc52.

- ac3enc: use generic fixed-point mdct · 79997def
  Mans Rullgard authored 14 years ago
```
This makes the AC3 encoder use the shared fixed-point MDCT rather
than its own implementation.  The checksum changes are due to
different rounding in the MDCT.
