901ee2bea3 * some significant clean-up of the dv_decode_ac (it looks real 
simple now, take a look for yourself).

   * additional optimizations of the decoder. It runs at 55fps now
     on my desktop and it used to be ~45fps.

e7a18d5deb * moving some of the commonly used bit reading/writing functions 
from common.c -> common.h so that they can be inlined.
         + performace gain ~1% (measured with DV decoding)
	 + code bloat 0.05%
      Looks like a win-win solution.

e15c330246 * 3x encoding speedup. Finally we seem to be on par with libdv 
in terms of time and we're doing slightly better w.r.t. to
     quality. I don't think there's much room for improvement
     left, but I'd like to try and vectorize a couple of things.
     Btw, any ideas on what may impact performance will be greatly
     appreciated.

4fa1c4fa8d * preAlpha DV encoding support -- there's still a truckload 
of work to do, but it least people can try it out and share
      ideas. Please don't hesitate to give it a spin:

         $ ffmpeg -i file.avi file.dv

      is all you need.

    * fix for a deallocation bug in DV muxer

7458ccbb02 * DV handling was streamlined for both muxing/demuxing and 
decoding. All muxing/demuxing functionality is now available
     in libavformat/dv.[ch].

   * dv1394.c and avidec.c were hooked up with general DV demuxer.

   * DVAUDIO is dead! Long live pcm_s16le!

   * DV audio is now always recognized -- which means we can
     now hear all those ducks quaking in pond.dv.
