  522. play them (only tested video)
  523. - fixed H.263 white bug

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

  542. - changed the FOURCC code for H.263 to "U263" to be able to see the
  543. +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
  544. this +codec ;) (JuanJo).
  545. - Halfpel motion estimation after MB type selection (JuanJo)
  546. - added pgm and .Y.U.V output format
  547. - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
  548. output.
  549. - added pgmpipe I/O format (original patch from Martin Aumueller
  550. <lists at reserv.at>, but changed completely since we use a format
  551. instead of a protocol)
  552. version 0.4.2:
  553. - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
  554. (for OpenDivX) is almost complete: 8x8 MVs and rounding are
  555. missing. MSMPEG4 support is complete.
  556. - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
  557. can decode ffmpeg MPEGs :-)).
  558. - added libavcodec API documentation (see apiexample.c).
  559. - fixed image polyphase bug (the bottom of some images could be
  560. greenish)
  561. - added support for non clipped motion vectors (decoding only)
  562. and image sizes non-multiple of 16
  563. - added support for AC prediction (decoding only)
  564. - added file overwrite confirmation (can be disabled with -y)
  565. - added custom size picture to H.263 using H.263+ (Juanjo)
  566. version 0.4.1:
  567. - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
  568. of AVI and ASF to DIV3.
  569. - added -me option to set motion estimation method
  570. (default=log). suppressed redundant -hq option.
  571. - added options -acodec and -vcodec to force a given codec (useful for
  572. AVI for example)
  573. - fixed -an option
  574. - improved dct_quantize speed
  575. - factorized some motion estimation code
  576. version 0.4.0:
  577. - removing grab code from ffserver and moved it to ffmpeg. Added
  578. multistream support to ffmpeg.
  579. - added timeshifting support for live feeds (option ?date=xxx in the
  580. URL)
  581. - added high quality image resize code with polyphase filter (need
  582. mmx/see optimization). Enable multiple image size support in ffserver.
  583. - added multi live feed support in ffserver
  584. - suppressed master feature from ffserver (it should be done with an
  585. external program which opens the .ffm url and writes it to another
  586. ffserver)
  587. - added preliminary support for video stream parsing (WAV and AVI half
  588. done). Added proper support for audio/video file conversion in
  589. ffmpeg.
  590. - added preliminary support for video file sending from ffserver
  591. - redesigning I/O subsystem: now using URL based input and output
  592. (see avio.h)

  602. - added stereo in MPEG audio encoder
  603. version 0.3.3:
  604. - added 'high quality' mode which use motion vectors. It can be used in
  605. real time at low resolution.
  606. - fixed rounding problems which caused quality problems at high
  607. bitrates and large GOP size
  608. version 0.3.2: small fixes
