Added PGM format (=grey + pgm). Renamed old PGM to PGMYUV. +- fixed msmpeg4 slice issues (tell me if you still find problems). +- fixed opendivx bugs with newer versions (added VOL header decoding). +- added support for mplayer interface. + +version 0.4.4: + +- fixed some std header definitions (Bjorn Lindgren + <bjorn.e.lindgren@telia.com>). +- added mpeg demux (mpeg 1 and 2 compatible). +- added ASF demux. +- added prototype RM demux. +- added AC3 decoding (done with libac3 by Aaron Holtzman). +- added decoding codec parameter guessing (.e.g. for mpeg, because the + header does not include them). +- fixed header generation in mpeg1, AVI and ASF mux : wmplayer can now + play them (only tested video). +- fixed h263 white bug. +- fixed phase rounding in img resample filter. +- add mmx code for polyphase img resample filter. +- added CPU autodetect. +- added generic title/author/copyright/comment string handling (ASF and RM use them). +- added SWF demux to extract MP3 track (not usable yet because no MP3 + decoder). +- added fractional frame rate support. +- codecs are no longer searched by read_header() (should fix ffserver + segfault). + +version 0.4.3: + +- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq@amsat.org>). +- fixed raw yuv output. +- added motion rounding support in MPEG4. +- fixed motion bug rounding in MSMPEG4. +- added B frame handling in video core. +- added full MPEG1 decoding support. +- added partial (frame only) MPEG2 support. +- changed the FOURCC code for H.263 to "U263" to be able to see the ++AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with +this +codec ;) (JuanJo). +- Halfpel motion estimation after mb type selection (JuanJo). +- added pgm and .Y.U.V output format. +- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or + output. +- added pgmpipe I/O format (original patch from Martin Aumueller + <lists@reserv.at>, but changed completely since we use a format + instead of a protocol). + +version 0.4.2: + +- added H263/MPEG4/MSMPEG4 decoding support. MPEG4 decoding support + (for openDIVX) is almost complete: 8x8 MVs and rounding are + missing. MSMPEG4 support is complete. +- added prototype MPEG1 decoder. Only I and P frames handled yet (it + can decode ffmpeg mpegs :-)). +- added libavcodec API documentation (see apiexample.c). +- fixed image polyphase bug (the bottom of some images could be + greenish). +- added support for non clipped motion vectors (decoding only) + and image sizes non multiple of 16. +- added support for AC prediction (decoding only). +- added file overwrite confirmation (can be disabled with -y). +- Added custom size picture to H.263 using H.263+ (Juanjo). + +version 0.4.1: + +- added MSMPEG4 (aka DIVX) compatible encoder. Changed default codec + of avi and asf to DIV3. +- added -me option to set motion estimation method + (default=log). suppressed redundant -hq option. +- added options -acodec and -vcodec to force a given codec (useful for + AVI for example). +- fixed -an option. +- improved dct_quantize speed. +- factorized some motion estimation code. + +version 0.4.0: + +- removing grab code from ffserver and moved it to ffmpeg. Added multi + stream support to ffmpeg. +- added timeshifting support for live feeds (option ?date=xxx in the + URL). +- added high quality image resize code with polyphase filter (need + mmx/see optimisation). Enable multiple image size support in ffserver. +- added multi live feed support in ffserver. +- suppressed master feature from ffserver (it should be done with an + external program which opens the .ffm url and writes it to another + ffserver). +- added preliminary support for video stream parsing (wav and avi half + done). Added proper support for audio/video file convertion in + ffmpeg. +- added preliminary support for video file sending from ffserver. +- redesigning I/O subsystem : now using URL based input and output + (see avio.h). +- added wav format support. +- added "tty user interface" to ffmpeg to stop grabbing gracefully. +- added MMX/SSE optimizations to SAD (Sums of Absolutes Diferences) + (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo@atmlab.utfsm.cl>). +- added MMX DCT from mpeg2_movie 1.5 (Juanjo). +- added new motion estimation algorithms, log and phods (Juanjo). +- changed directories : libav for format handling, libavcodec for + codecs. + +version 0.3.4: + +- added stereo in mpeg audio encoder. + +version 0.3.3: + +- added 'high quality' mode which use motion vectors. It can be used in + real time at low resolution. +- fixed rounding problems which caused quality problems at high + bitrates and large gop size. + +version 0.3.2: small fixes + +- asf fixes +- put_seek bug fix + +version 0.3.1: added avi/divx support + +- added avi support +- added mpeg4 codec compatible with open divx. It is based on the h263 + codec. +- added sound for flash format (not tested) + +version 0.3: initial public release |
