  this +codec ;) (JuanJo).
581
- Halfpel motion estimation after MB type selection (JuanJo)
582
- added pgm and .Y.U.V output format

586
  <lists at reserv.at>, but changed completely since we use a format
587
  instead of a protocol)

594
  missing. MSMPEG4 support is complete.
595

596
  can decode ffmpeg MPEGs :-)).

- added -me option to set motion estimation method
612
  (default=log). suppressed redundant -hq option.

- added timeshifting support for live feeds (option ?date=xxx in the
625
  URL)
626
- added high quality image resize code with polyphase filter (need
627
  mmx/see optimization). Enable multiple image size support in ffserver.
628
- added multi live feed support in ffserver
629
- suppressed master feature from ffserver (it should be done with an
630
  external program which opens the .ffm url and writes it to another
631
  ffserver)
632

633
  done). Added proper support for audio/video file conversion in
634
