  470. - added full MPEG-1 decoding support
  471. - added partial (frame only) MPEG-2 support
  472. - changed the FOURCC code for H.263 to "U263" to be able to see the
  473. +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
  474. this +codec ;) (JuanJo).
  475. - Halfpel motion estimation after MB type selection (JuanJo)
  476. - added pgm and .Y.U.V output format
  477. - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
  478. output.
  479. - added pgmpipe I/O format (original patch from Martin Aumueller
  480. <lists at reserv.at>, but changed completely since we use a format
  481. instead of a protocol)
  482. version 0.4.2:
  483. - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
  484. (for OpenDivX) is almost complete: 8x8 MVs and rounding are
  485. missing. MSMPEG4 support is complete.
  486. - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
  487. can decode ffmpeg MPEGs :-)).
  488. - added libavcodec API documentation (see apiexample.c).
  489. - fixed image polyphase bug (the bottom of some images could be
  490. greenish)
  491. - added support for non clipped motion vectors (decoding only)
  492. and image sizes non-multiple of 16
  493. - added support for AC prediction (decoding only)
  494. - added file overwrite confirmation (can be disabled with -y)
  495. - added custom size picture to H.263 using H.263+ (Juanjo)
  496. version 0.4.1:
  497. - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
  498. of AVI and ASF to DIV3.
  499. - added -me option to set motion estimation method
  500. (default=log). suppressed redundant -hq option.
  501. - added options -acodec and -vcodec to force a given codec (useful for
  502. AVI for example)
  503. - fixed -an option
  504. - improved dct_quantize speed
  505. - factorized some motion estimation code
  506. version 0.4.0:
  507. - removing grab code from ffserver and moved it to ffmpeg. Added
  508. multistream support to ffmpeg.
  509. - added timeshifting support for live feeds (option ?date=xxx in the
  510. URL)
  511. - added high quality image resize code with polyphase filter (need
  512. mmx/see optimization). Enable multiple image size support in ffserver.
  513. - added multi live feed support in ffserver
  514. - suppressed master feature from ffserver (it should be done with an
  515. external program which opens the .ffm url and writes it to another
  516. ffserver)
  517. - added preliminary support for video stream parsing (WAV and AVI half
  518. done). Added proper support for audio/video file conversion in
  519. ffmpeg.
  520. - added preliminary support for video file sending from ffserver
  521. - redesigning I/O subsystem: now using URL based input and output
  522. (see avio.h)
  523. - added WAV format support
  524. - added "tty user interface" to ffmpeg to stop grabbing gracefully
  525. - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
  526. (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
  527. - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
  528. - added new motion estimation algorithms, log and phods (Juanjo)
  529. - changed directories: libav for format handling, libavcodec for
  530. codecs
  531. version 0.3.4:
  532. - added stereo in MPEG audio encoder
  533. version 0.3.3:
  534. - added 'high quality' mode which use motion vectors. It can be used in
  535. real time at low resolution.
  536. - fixed rounding problems which caused quality problems at high
  537. bitrates and large GOP size
  538. version 0.3.2: small fixes
  539. - ASF fixes
  540. - put_seek bug fix
  541. version 0.3.1: added avi/divx support
  542. - added AVI support
  543. - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
  544. - added sound for flash format (not tested)
  545. version 0.3: initial public release
