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

4cb3f3b637 Using the extension m4a for audio only MPEG-4 files is increasingly 
common, especially since Apple iTunes treats files with the two
extensions differently. Without the patch, FFmpeg won't know that m4a
is for MPEG-4 files

ffaa816ee3 recommit of 
* fixing an unitilaized field AVImageInfo::interleaved.

      As a matter of fact we have two problems here: first
      AVImageInfo::interleaved is never initialzed in img.c.
      The second problem is that even if we want interleaved
      PNGs there's a bug in png.c that prevents us from generating
      them.

      The later problem is for somebody familiar with PNG to
      handle.

      And yes, always setting AVImageInfo::interleaved to 0 isn't
      such a good idea, but it still beats garbage values.
