631670888d * introducing new public interface in imgconvert.c 
+ avcodec_get_pix_fmt
         converts textual representation of pixel format into
	 the actual id. Complements avcodec_get_pix_fmt_name.
       + avpicture_layout
         serializes given picture into a flat array.
	 Complements avpicture_fill.

   * adding a new option -pix_fmt to the ffmpeg, in order to control
     pixel format for the codecs that do support it, like rawvideo,
     for example.

   * reducing complexity of the rawvideo codec by splitting it in two
     and making it more reliable via hooking up to the avpicture_layout.
     Plus adding new FourCC as described here: http://www.fourcc.org

   * A tiny fix for avienc.c that makes avih and video strf consistent
     regarding codec FourCC.

44ae98ddef fixed buffer allocation logic (hopefully) so that decoder does not crash 
most ffmpeg-enabled apps; added a bunch on motion compensation stuff
which is effectively disabled at the moment while details are worked out

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 ?
