de6d9b64 398- codecs are no longer searched by read_header() (should fix ffserver
e0db8cfb 399 segfault)

404
dd5cf2ad 405- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
e0db8cfb
DB
406- fixed raw yuv output
407- added motion rounding support in MPEG-4
408- fixed motion bug rounding in MSMPEG4
409- added B-frame handling in video core
410- added full MPEG-1 decoding support
411- added partial (frame only) MPEG-2 support
de6d9b64 412- changed the FOURCC code for H.263 to "U263" to be able to see the
e0db8cfb
DB
413 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
414 this +codec ;) (JuanJo).
415- Halfpel motion estimation after MB type selection (JuanJo)
416- added pgm and .Y.U.V output format
de6d9b64
FB
417- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
418 output.
419- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 420 <lists at reserv.at>, but changed completely since we use a format
e0db8cfb 421 instead of a protocol)

e0db8cfb
DB
427- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
428 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 429 missing. MSMPEG4 support is complete.
e0db8cfb
DB
430- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
431 can decode ffmpeg MPEGs :-)).
de6d9b64
FB
432- added libavcodec API documentation (see apiexample.c).
433- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 434 greenish)
de6d9b64 435- added support for non clipped motion vectors (decoding only)
e0db8cfb
DB
436 and image sizes non-multiple of 16
437- added support for AC prediction (decoding only)
438- added file overwrite confirmation (can be disabled with -y)

446- added -me option to set motion estimation method
447 (default=log). suppressed redundant -hq option.
448- added options -acodec and -vcodec to force a given codec (useful for
e0db8cfb
DB
449 AVI for example)
450- fixed -an option
451- improved dct_quantize speed
452- factorized some motion estimation code

459 multistream support to ffmpeg.
de6d9b64 460- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 461 URL)
de6d9b64 462- added high quality image resize code with polyphase filter (need
56cc85a0 463 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 464- added multi live feed support in ffserver
de6d9b64
FB
465- suppressed master feature from ffserver (it should be done with an
466 external program which opens the .ffm url and writes it to another
e0db8cfb
DB
467 ffserver)
468- added preliminary support for video stream parsing (WAV and AVI half
469 done). Added proper support for audio/video file conversion in
de6d9b64 470 ffmpeg.
e0db8cfb
DB
471- added preliminary support for video file sending from ffserver
472- redesigning I/O subsystem: now using URL based input and output
473 (see avio.h)
474- added WAV format support
475- added "tty user interface" to ffmpeg to stop grabbing gracefully
476- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
