  531. decoder)
  532. - added fractional frame rate support

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

  558. can decode ffmpeg MPEGs :-)).

  560. - fixed image polyphase bug (the bottom of some images could be
  561. greenish)

  563. and image sizes non-multiple of 16
  564. - added support for AC prediction (decoding only)

  569. of AVI and ASF to DIV3.
  570. - added -me option to set motion estimation method
  571. (default=log). suppressed redundant -hq option.
  572. - added options -acodec and -vcodec to force a given codec (useful for
  573. AVI for example)
  574. - fixed -an option
  575. - improved dct_quantize speed
  576. - factorized some motion estimation code
  577. version 0.4.0:

  579. multistream support to ffmpeg.
  580. - added timeshifting support for live feeds (option ?date=xxx in the
  581. URL)
  582. - added high quality image resize code with polyphase filter (need
  583. mmx/see optimization). Enable multiple image size support in ffserver.
  584. - added multi live feed support in ffserver
  585. - suppressed master feature from ffserver (it should be done with an
  586. external program which opens the .ffm url and writes it to another
  587. ffserver)
  588. - added preliminary support for video stream parsing (WAV and AVI half
  589. done). Added proper support for audio/video file conversion in
  590. ffmpeg.
  591. - added preliminary support for video file sending from ffserver
  592. - redesigning I/O subsystem: now using URL based input and output
  593. (see avio.h)
