399- added CPU autodetection
400- added generic title/author/copyright/comment string handling (ASF and RM
401 use them)
de6d9b64 402- added SWF demux to extract MP3 track (not usable yet because no MP3
e0db8cfb
DB
403 decoder)
404- added fractional frame rate support
de6d9b64 405- codecs are no longer searched by read_header() (should fix ffserver
e0db8cfb 406 segfault)

411
dd5cf2ad 412- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
e0db8cfb
DB
413- fixed raw yuv output
414- added motion rounding support in MPEG-4
415- fixed motion bug rounding in MSMPEG4
416- added B-frame handling in video core
417- added full MPEG-1 decoding support
418- added partial (frame only) MPEG-2 support
de6d9b64 419- changed the FOURCC code for H.263 to "U263" to be able to see the
e0db8cfb
DB
420 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
421 this +codec ;) (JuanJo).
422- Halfpel motion estimation after MB type selection (JuanJo)
423- added pgm and .Y.U.V output format
de6d9b64
FB
424- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
425 output.
426- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 427 <lists at reserv.at>, but changed completely since we use a format
e0db8cfb 428 instead of a protocol)

e0db8cfb
DB
434- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
435 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 436 missing. MSMPEG4 support is complete.
e0db8cfb
DB
437- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
438 can decode ffmpeg MPEGs :-)).
de6d9b64
FB
439- added libavcodec API documentation (see apiexample.c).
440- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 441 greenish)
de6d9b64 442- added support for non clipped motion vectors (decoding only)
e0db8cfb
DB
443 and image sizes non-multiple of 16
444- added support for AC prediction (decoding only)
445- added file overwrite confirmation (can be disabled with -y)
446- added custom size picture to H.263 using H.263+ (Juanjo)

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

466 multistream support to ffmpeg.
de6d9b64 467- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 468 URL)
de6d9b64 469- added high quality image resize code with polyphase filter (need
56cc85a0 470 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 471- added multi live feed support in ffserver
de6d9b64
FB
472- suppressed master feature from ffserver (it should be done with an
473 external program which opens the .ffm url and writes it to another
e0db8cfb
DB
474 ffserver)
475- added preliminary support for video stream parsing (WAV and AVI half
476 done). Added proper support for audio/video file conversion in
de6d9b64 477 ffmpeg.
e0db8cfb
DB
478- added preliminary support for video file sending from ffserver
479- redesigning I/O subsystem: now using URL based input and output
480 (see avio.h)
481- added WAV format support
482- added "tty user interface" to ffmpeg to stop grabbing gracefully
483- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
