  536. decoder)
  537. - added fractional frame rate support

  548. - changed the FOURCC code for H.263 to "U263" to be able to see the
  549. +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
  550. this +codec ;) (JuanJo).
  551. - Halfpel motion estimation after MB type selection (JuanJo)
  552. - added pgm and .Y.U.V output format
  553. - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
  554. output.
  555. - added pgmpipe I/O format (original patch from Martin Aumueller
  556. <lists at reserv.at>, but changed completely since we use a format
  557. instead of a protocol)
  558. version 0.4.2:
  559. - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
  560. (for OpenDivX) is almost complete: 8x8 MVs and rounding are
  561. missing. MSMPEG4 support is complete.

  574. of AVI and ASF to DIV3.
  575. - added -me option to set motion estimation method
  576. (default=log). suppressed redundant -hq option.
  577. - added options -acodec and -vcodec to force a given codec (useful for
  578. AVI for example)

  580. - improved dct_quantize speed
  581. - factorized some motion estimation code

  586. URL)
  587. - added high quality image resize code with polyphase filter (need
  588. mmx/see optimization). Enable multiple image size support in ffserver.
  589. - added multi live feed support in ffserver
  590. - suppressed master feature from ffserver (it should be done with an
  591. external program which opens the .ffm url and writes it to another
  592. ffserver)
  593. - added preliminary support for video stream parsing (WAV and AVI half
  594. done). Added proper support for audio/video file conversion in
  595. ffmpeg.
  596. - added preliminary support for video file sending from ffserver
