      avcodec/pthread_slice: use slice threading from avutil · b505f15b
      Muhammad Faiz authored
      Also remove pthread_cond_broadcast(progress_cond) on uninit.
      Broadcasting it is not required because workers are always
      parked when they are not in thread_execute. So it is imposible
      that a worker is waiting on progress_cond when uninitialized.
      
      Benchmark:
      ./ffmpeg -threads $threads -thread_type slice -i 10slices.mp4 -f null null
