1 version 0.4.6:
2

9 version 0.4.5:
10
11 - some header fixes (Zdenek Kabelac <kabi@informatics.muni.cz>).
12 - many MMX optimizations (Nick Kurshev <nickols_k@mail.ru>).
13 - added configure system (actually a small shell script).
14 - added mpeg audio layer 1/2/3 decoding using LGPL'ed mpglib by
15 Michael Hipp (temporary solution - waiting for integer only
16 decoder).
17 - fixed VIDIOCSYNC interrupt.
18 - added Intel H263 decoding support ('I263' avi fourCC)
19 - added Real Video 1.0 decoding (needs further testing).
20 - simplified image formats again. Added PGM format (=grey
21 pgm). Renamed old PGM to PGMYUV.
22 - fixed msmpeg4 slice issues (tell me if you still find problems).
23 - fixed opendivx bugs with newer versions (added VOL header decoding).
24 - added support for mplayer interface.

39 version 0.4.4:
40
41 - fixed some std header definitions (Bjorn Lindgren
42 <bjorn.e.lindgren@telia.com>).
43 - added mpeg demux (mpeg 1 and 2 compatible).
44 - added ASF demux.
45 - added prototype RM demux.
46 - added AC3 decoding (done with libac3 by Aaron Holtzman).
47 - added decoding codec parameter guessing (.e.g. for mpeg, because the
48 header does not include them).
49 - fixed header generation in mpeg1, AVI and ASF mux : wmplayer can now
50 play them (only tested video).
51 - fixed h263 white bug.
52 - fixed phase rounding in img resample filter.
53 - add mmx code for polyphase img resample filter.
54 - added CPU autodetect.
55 - added generic title/author/copyright/comment string handling (ASF and RM use them).
56 - added SWF demux to extract MP3 track (not usable yet because no MP3
57 decoder).
58 - added fractional frame rate support.
59 - codecs are no longer searched by read_header() (should fix ffserver
60 segfault).
61
62 version 0.4.3:
63
64 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq@amsat.org>).
65 - fixed raw yuv output.
66 - added motion rounding support in MPEG4.
67 - fixed motion bug rounding in MSMPEG4.
68 - added B frame handling in video core.
69 - added full MPEG1 decoding support.
70 - added partial (frame only) MPEG2 support.
71 - changed the FOURCC code for H.263 to "U263" to be able to see the
72 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
73 this +codec ;) (JuanJo).
74 - Halfpel motion estimation after mb type selection (JuanJo).
75 - added pgm and .Y.U.V output format.
76 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
77 output.
78 - added pgmpipe I/O format (original patch from Martin Aumueller
79 <lists@reserv.at>, but changed completely since we use a format
80 instead of a protocol).
81
82 version 0.4.2:
83
84 - added H263/MPEG4/MSMPEG4 decoding support. MPEG4 decoding support
85 (for openDIVX) is almost complete: 8x8 MVs and rounding are
86 missing. MSMPEG4 support is complete.
87 - added prototype MPEG1 decoder. Only I and P frames handled yet (it
88 can decode ffmpeg mpegs :-)).
89 - added libavcodec API documentation (see apiexample.c).
90 - fixed image polyphase bug (the bottom of some images could be
91 greenish).
92 - added support for non clipped motion vectors (decoding only)
93 and image sizes non multiple of 16.
94 - added support for AC prediction (decoding only).
95 - added file overwrite confirmation (can be disabled with -y).
96 - Added custom size picture to H.263 using H.263+ (Juanjo).
97
98 version 0.4.1:
99
100 - added MSMPEG4 (aka DIVX) compatible encoder. Changed default codec
101 of avi and asf to DIV3.
102 - added -me option to set motion estimation method
103 (default=log). suppressed redundant -hq option.
104 - added options -acodec and -vcodec to force a given codec (useful for
105 AVI for example).
106 - fixed -an option.
107 - improved dct_quantize speed.
108 - factorized some motion estimation code.
109
110 version 0.4.0:
111
112 - removing grab code from ffserver and moved it to ffmpeg. Added multi
113 stream support to ffmpeg.
114 - added timeshifting support for live feeds (option ?date=xxx in the
115 URL).
116 - added high quality image resize code with polyphase filter (need
117 mmx/see optimisation). Enable multiple image size support in ffserver.
118 - added multi live feed support in ffserver.
119 - suppressed master feature from ffserver (it should be done with an
120 external program which opens the .ffm url and writes it to another
121 ffserver).
122 - added preliminary support for video stream parsing (wav and avi half
123 done). Added proper support for audio/video file convertion in
124 ffmpeg.
125 - added preliminary support for video file sending from ffserver.
126 - redesigning I/O subsystem : now using URL based input and output
127 (see avio.h).
128 - added wav format support.
129 - added "tty user interface" to ffmpeg to stop grabbing gracefully.
130 - added MMX/SSE optimizations to SAD (Sums of Absolutes Diferences)
131 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo@atmlab.utfsm.cl>).
132 - added MMX DCT from mpeg2_movie 1.5 (Juanjo).
133 - added new motion estimation algorithms, log and phods (Juanjo).
134 - changed directories : libav for format handling, libavcodec for
135 codecs.
136
137 version 0.3.4:
138
139 - added stereo in mpeg audio encoder.
140
141 version 0.3.3:
142
143 - added 'high quality' mode which use motion vectors. It can be used in
144 real time at low resolution.
145 - fixed rounding problems which caused quality problems at high
146 bitrates and large gop size.
147
148 version 0.3.2: small fixes
149
150 - asf fixes
151 - put_seek bug fix
152
153 version 0.3.1: added avi/divx support
154
155 - added avi support
156 - added mpeg4 codec compatible with open divx. It is based on the h263
157 codec.
158 - added sound for flash format (not tested)
