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

409
dd5cf2ad 410- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
e0db8cfb
DB
411- fixed raw yuv output
412- added motion rounding support in MPEG-4
413- fixed motion bug rounding in MSMPEG4
414- added B-frame handling in video core
415- added full MPEG-1 decoding support
416- added partial (frame only) MPEG-2 support
de6d9b64 417- changed the FOURCC code for H.263 to "U263" to be able to see the
e0db8cfb
DB
418 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
419 this +codec ;) (JuanJo).
420- Halfpel motion estimation after MB type selection (JuanJo)
421- added pgm and .Y.U.V output format
de6d9b64
FB
422- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
423 output.
424- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 425 <lists at reserv.at>, but changed completely since we use a format
e0db8cfb 426 instead of a protocol)

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

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

464 multistream support to ffmpeg.
de6d9b64 465- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 466 URL)
de6d9b64 467- added high quality image resize code with polyphase filter (need
56cc85a0 468 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 469- added multi live feed support in ffserver
de6d9b64
FB
470- suppressed master feature from ffserver (it should be done with an
471 external program which opens the .ffm url and writes it to another
e0db8cfb
DB
472 ffserver)
473- added preliminary support for video stream parsing (WAV and AVI half
474 done). Added proper support for audio/video file conversion in
de6d9b64 475 ffmpeg.
e0db8cfb
DB
476- added preliminary support for video file sending from ffserver
477- redesigning I/O subsystem: now using URL based input and output
478 (see avio.h)
479- added WAV format support
480- added "tty user interface" to ffmpeg to stop grabbing gracefully
481- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
