fixed mb_intra_vlc decoding table size
[libav.git] / Changelog
1version 0.4.5:
3- some header fixes (Zdenek Kabelac <>).
4- many MMX optimizations (Nick Kurshev <>).
5- added configure system (actually a small shell script).
6- added mpeg audio layer 1/2/3 decoding using LGPL'ed mpglib by
7 Michael Hipp (temporary solution - waiting for integer only
8 decoder).
9- fixed VIDIOCSYNC interrupt.
10- added Intel H263 decoding support ('I263' avi fourCC)
11- added Real Video 1.0 decoding (needs further testing).
12- simplified image formats again. Added PGM format (=grey
13 pgm). Renamed old PGM to PGMYUV.
14- fixed msmpeg4 slice issues (tell me if you still find problems).
15- fixed opendivx bugs with newer versions (added VOL header decoding).
16- added support for mplayer interface.
17- added macroblock skip optimization.
18- added MJPEG decoder (still lacking some jpeg features).
19- added mmx/mmxext idct from libmpeg2.
21version 0.4.4:
23- fixed some std header definitions (Bjorn Lindgren
24 <>).
25- added mpeg demux (mpeg 1 and 2 compatible).
26- added ASF demux.
27- added prototype RM demux.
28- added AC3 decoding (done with libac3 by Aaron Holtzman).
29- added decoding codec parameter guessing (.e.g. for mpeg, because the
30 header does not include them).
31- fixed header generation in mpeg1, AVI and ASF mux : wmplayer can now
32 play them (only tested video).
33- fixed h263 white bug.
34- fixed phase rounding in img resample filter.
35- add mmx code for polyphase img resample filter.
36- added CPU autodetect.
37- added generic title/author/copyright/comment string handling (ASF and RM use them).
38- added SWF demux to extract MP3 track (not usable yet because no MP3
39 decoder).
40- added fractional frame rate support.
41- codecs are no longer searched by read_header() (should fix ffserver
42 segfault).
44version 0.4.3:
46- BGR24 patch (initial patch by Jeroen Vreeken <>).
47- fixed raw yuv output.
48- added motion rounding support in MPEG4.
49- fixed motion bug rounding in MSMPEG4.
50- added B frame handling in video core.
51- added full MPEG1 decoding support.
52- added partial (frame only) MPEG2 support.
53- changed the FOURCC code for H.263 to "U263" to be able to see the
54+AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
55this +codec ;) (JuanJo).
56- Halfpel motion estimation after mb type selection (JuanJo).
57- added pgm and .Y.U.V output format.
58- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
59 output.
60- added pgmpipe I/O format (original patch from Martin Aumueller
61 <>, but changed completely since we use a format
62 instead of a protocol).
64version 0.4.2:
66- added H263/MPEG4/MSMPEG4 decoding support. MPEG4 decoding support
67 (for openDIVX) is almost complete: 8x8 MVs and rounding are
68 missing. MSMPEG4 support is complete.
69- added prototype MPEG1 decoder. Only I and P frames handled yet (it
70 can decode ffmpeg mpegs :-)).
71- added libavcodec API documentation (see apiexample.c).
72- fixed image polyphase bug (the bottom of some images could be
73 greenish).
74- added support for non clipped motion vectors (decoding only)
75 and image sizes non multiple of 16.
76- added support for AC prediction (decoding only).
77- added file overwrite confirmation (can be disabled with -y).
78- Added custom size picture to H.263 using H.263+ (Juanjo).
80version 0.4.1:
82- added MSMPEG4 (aka DIVX) compatible encoder. Changed default codec
83 of avi and asf to DIV3.
84- added -me option to set motion estimation method
85 (default=log). suppressed redundant -hq option.
86- added options -acodec and -vcodec to force a given codec (useful for
87 AVI for example).
88- fixed -an option.
89- improved dct_quantize speed.
90- factorized some motion estimation code.
92version 0.4.0:
94- removing grab code from ffserver and moved it to ffmpeg. Added multi
95 stream support to ffmpeg.
96- added timeshifting support for live feeds (option ?date=xxx in the
97 URL).
98- added high quality image resize code with polyphase filter (need
99 mmx/see optimisation). Enable multiple image size support in ffserver.
100- added multi live feed support in ffserver.
101- suppressed master feature from ffserver (it should be done with an
102 external program which opens the .ffm url and writes it to another
103 ffserver).
104- added preliminary support for video stream parsing (wav and avi half
105 done). Added proper support for audio/video file convertion in
106 ffmpeg.
107- added preliminary support for video file sending from ffserver.
108- redesigning I/O subsystem : now using URL based input and output
109 (see avio.h).
110- added wav format support.
111- added "tty user interface" to ffmpeg to stop grabbing gracefully.
112- added MMX/SSE optimizations to SAD (Sums of Absolutes Diferences)
113 (Juan J. Sierralta P. a.k.a. "Juanjo" <>).
114- added MMX DCT from mpeg2_movie 1.5 (Juanjo).
115- added new motion estimation algorithms, log and phods (Juanjo).
116- changed directories : libav for format handling, libavcodec for
117 codecs.
119version 0.3.4:
121- added stereo in mpeg audio encoder.
123version 0.3.3:
125- added 'high quality' mode which use motion vectors. It can be used in
126 real time at low resolution.
127- fixed rounding problems which caused quality problems at high
128 bitrates and large gop size.
130version 0.3.2: small fixes
132- asf fixes
133- put_seek bug fix
135version 0.3.1: added avi/divx support
137- added avi support
138- added mpeg4 codec compatible with open divx. It is based on the h263
139 codec.
140- added sound for flash format (not tested)
142version 0.3: initial public release
