fixed raw read for eof
[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.
16fbebe1 17- added macroblock skip optimization.
0c1e384c 18- added MJPEG decoder.
16fbebe1 19- added mmx/mmxext idct from libmpeg2.
20- added pgmyuvpipe, ppm, and ppm_pipe formats (original patch by Celer
21 <>).
22- added pixel format convertion layer (e.g. for MJPEG or PPM).
23- added deinterlacing option.
24- mpeg1/2 fixes.
25- mpeg4 vol header fixes (Jonathan Marsden <>).
26- ARM optimizations (Lionel Ulmer <>).
27- Windows porting of file converter.
28- added MJPEG raw format (input/ouput).
29- added JPEG image format support (input/output).
31version 0.4.4:
33- fixed some std header definitions (Bjorn Lindgren
34 <>).
35- added mpeg demux (mpeg 1 and 2 compatible).
36- added ASF demux.
37- added prototype RM demux.
38- added AC3 decoding (done with libac3 by Aaron Holtzman).
39- added decoding codec parameter guessing (.e.g. for mpeg, because the
40 header does not include them).
41- fixed header generation in mpeg1, AVI and ASF mux : wmplayer can now
42 play them (only tested video).
43- fixed h263 white bug.
44- fixed phase rounding in img resample filter.
45- add mmx code for polyphase img resample filter.
46- added CPU autodetect.
47- added generic title/author/copyright/comment string handling (ASF and RM use them).
48- added SWF demux to extract MP3 track (not usable yet because no MP3
49 decoder).
50- added fractional frame rate support.
51- codecs are no longer searched by read_header() (should fix ffserver
52 segfault).
54version 0.4.3:
56- BGR24 patch (initial patch by Jeroen Vreeken <>).
57- fixed raw yuv output.
58- added motion rounding support in MPEG4.
59- fixed motion bug rounding in MSMPEG4.
60- added B frame handling in video core.
61- added full MPEG1 decoding support.
62- added partial (frame only) MPEG2 support.
63- changed the FOURCC code for H.263 to "U263" to be able to see the
64+AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
65this +codec ;) (JuanJo).
66- Halfpel motion estimation after mb type selection (JuanJo).
67- added pgm and .Y.U.V output format.
68- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
69 output.
70- added pgmpipe I/O format (original patch from Martin Aumueller
71 <>, but changed completely since we use a format
72 instead of a protocol).
74version 0.4.2:
76- added H263/MPEG4/MSMPEG4 decoding support. MPEG4 decoding support
77 (for openDIVX) is almost complete: 8x8 MVs and rounding are
78 missing. MSMPEG4 support is complete.
79- added prototype MPEG1 decoder. Only I and P frames handled yet (it
80 can decode ffmpeg mpegs :-)).
81- added libavcodec API documentation (see apiexample.c).
82- fixed image polyphase bug (the bottom of some images could be
83 greenish).
84- added support for non clipped motion vectors (decoding only)
85 and image sizes non multiple of 16.
86- added support for AC prediction (decoding only).
87- added file overwrite confirmation (can be disabled with -y).
88- Added custom size picture to H.263 using H.263+ (Juanjo).
90version 0.4.1:
92- added MSMPEG4 (aka DIVX) compatible encoder. Changed default codec
93 of avi and asf to DIV3.
94- added -me option to set motion estimation method
95 (default=log). suppressed redundant -hq option.
96- added options -acodec and -vcodec to force a given codec (useful for
97 AVI for example).
98- fixed -an option.
99- improved dct_quantize speed.
100- factorized some motion estimation code.
102version 0.4.0:
104- removing grab code from ffserver and moved it to ffmpeg. Added multi
105 stream support to ffmpeg.
106- added timeshifting support for live feeds (option ?date=xxx in the
107 URL).
108- added high quality image resize code with polyphase filter (need
109 mmx/see optimisation). Enable multiple image size support in ffserver.
110- added multi live feed support in ffserver.
111- suppressed master feature from ffserver (it should be done with an
112 external program which opens the .ffm url and writes it to another
113 ffserver).
114- added preliminary support for video stream parsing (wav and avi half
115 done). Added proper support for audio/video file convertion in
116 ffmpeg.
117- added preliminary support for video file sending from ffserver.
118- redesigning I/O subsystem : now using URL based input and output
119 (see avio.h).
120- added wav format support.
121- added "tty user interface" to ffmpeg to stop grabbing gracefully.
122- added MMX/SSE optimizations to SAD (Sums of Absolutes Diferences)
123 (Juan J. Sierralta P. a.k.a. "Juanjo" <>).
124- added MMX DCT from mpeg2_movie 1.5 (Juanjo).
125- added new motion estimation algorithms, log and phods (Juanjo).
126- changed directories : libav for format handling, libavcodec for
127 codecs.
129version 0.3.4:
131- added stereo in mpeg audio encoder.
133version 0.3.3:
135- added 'high quality' mode which use motion vectors. It can be used in
136 real time at low resolution.
137- fixed rounding problems which caused quality problems at high
138 bitrates and large gop size.
140version 0.3.2: small fixes
142- asf fixes
143- put_seek bug fix
145version 0.3.1: added avi/divx support
147- added avi support
148- added mpeg4 codec compatible with open divx. It is based on the h263
149 codec.
150- added sound for flash format (not tested)
152version 0.3: initial public release
