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.

10acc47995 * introducing dct248 into the DSP context.
* simple/accurate implementation of dct248
   * DV encoding now supports 2-4-8 DCT
   * DV encoding gets a bit faster (but still miles away
     from what I think it could do)
   * misc. DV codec cleanups

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.

880e8ba730 * fixing NTSC frame rate for DV streams
* let ffmpeg preserve 'aspect_ratio' for recoding.
  Do we want to make it tweakable from the command line ?
