395- added decoding codec parameter guessing (.e.g. for MPEG, because the
396 header does not include them)
397- fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
398 play them (only tested video)
399- fixed H.263 white bug
400- fixed phase rounding in img resample filter
401- add MMX code for polyphase img resample filter
402- added CPU autodetection
403- added generic title/author/copyright/comment string handling (ASF and RM
404 use them)
de6d9b64 405- added SWF demux to extract MP3 track (not usable yet because no MP3
e0db8cfb
DB
406 decoder)
407- added fractional frame rate support
de6d9b64 408- codecs are no longer searched by read_header() (should fix ffserver
e0db8cfb 409 segfault)

dd5cf2ad 415- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
e0db8cfb
DB
416- fixed raw yuv output
417- added motion rounding support in MPEG-4
418- fixed motion bug rounding in MSMPEG4
419- added B-frame handling in video core
420- added full MPEG-1 decoding support
421- added partial (frame only) MPEG-2 support
de6d9b64 422- changed the FOURCC code for H.263 to "U263" to be able to see the
e0db8cfb
DB
423 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
424 this +codec ;) (JuanJo).
425- Halfpel motion estimation after MB type selection (JuanJo)
426- added pgm and .Y.U.V output format
de6d9b64
FB
427- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
428 output.
429- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 430 <lists at reserv.at>, but changed completely since we use a format
e0db8cfb 431 instead of a protocol)

e0db8cfb
DB
437- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
438 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 439 missing. MSMPEG4 support is complete.
e0db8cfb
DB
440- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
441 can decode ffmpeg MPEGs :-)).
de6d9b64
FB
442- added libavcodec API documentation (see apiexample.c).
443- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 444 greenish)
de6d9b64 445- added support for non clipped motion vectors (decoding only)
e0db8cfb
DB
446 and image sizes non-multiple of 16
447- added support for AC prediction (decoding only)
448- added file overwrite confirmation (can be disabled with -y)
449- added custom size picture to H.263 using H.263+ (Juanjo)

455 of AVI and ASF to DIV3.
de6d9b64
FB
456- added -me option to set motion estimation method
457 (default=log). suppressed redundant -hq option.
458- added options -acodec and -vcodec to force a given codec (useful for
e0db8cfb
DB
459 AVI for example)
460- fixed -an option
461- improved dct_quantize speed
462- factorized some motion estimation code

469 multistream support to ffmpeg.
de6d9b64 470- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 471 URL)
de6d9b64 472- added high quality image resize code with polyphase filter (need
56cc85a0 473 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 474- added multi live feed support in ffserver
de6d9b64
FB
475- suppressed master feature from ffserver (it should be done with an
476 external program which opens the .ffm url and writes it to another
e0db8cfb
DB
477 ffserver)
478- added preliminary support for video stream parsing (WAV and AVI half
479 done). Added proper support for audio/video file conversion in
de6d9b64 480 ffmpeg.
e0db8cfb
DB
481- added preliminary support for video file sending from ffserver
482- redesigning I/O subsystem: now using URL based input and output
483 (see avio.h)
484- added WAV format support
485- added "tty user interface" to ffmpeg to stop grabbing gracefully
486- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
