21 | version 0.4.5: |
22 | ||
23 | - some header fixes (Zdenek Kabelac <kabi@informatics.muni.cz>). | |
24 | - many MMX optimizations (Nick Kurshev <nickols_k@mail.ru>). | |
25 | - added configure system (actually a small shell script). | |
26 | - added mpeg audio layer 1/2/3 decoding using LGPL'ed mpglib by | |
27 | Michael Hipp (temporary solution - waiting for integer only | |
28 | decoder). | |
29 | - fixed VIDIOCSYNC interrupt. | |
30 | - added Intel H263 decoding support ('I263' avi fourCC) | |
31 | - added Real Video 1.0 decoding (needs further testing). | |
32 | - simplified image formats again. Added PGM format (=grey | |
33 | pgm). Renamed old PGM to PGMYUV. | |
34 | - fixed msmpeg4 slice issues (tell me if you still find problems). | |
35 | - fixed opendivx bugs with newer versions (added VOL header decoding). | |
36 | - added support for mplayer interface. | |
16fbebe1 | 37 | - added macroblock skip optimization. |

16fbebe1 | 39 | - added mmx/mmxext idct from libmpeg2. |
0c1e384c FB |
40 | - added pgmyuvpipe, ppm, and ppm_pipe formats (original patch by Celer |
41 | <celer@shell.scrypt.net>). | |
42 | - added pixel format convertion layer (e.g. for MJPEG or PPM). | |
43 | - added deinterlacing option. | |
4a8c7a7f FB |

51 | version 0.4.4: | |
52 | ||
53 | - fixed some std header definitions (Bjorn Lindgren | |
54 | <bjorn.e.lindgren@telia.com>). | |
55 | - added mpeg demux (mpeg 1 and 2 compatible). | |
56 | - added ASF demux. | |
57 | - added prototype RM demux. | |
58 | - added AC3 decoding (done with libac3 by Aaron Holtzman). | |
59 | - added decoding codec parameter guessing (.e.g. for mpeg, because the | |
60 | header does not include them). | |
61 | - fixed header generation in mpeg1, AVI and ASF mux : wmplayer can now | |
62 | play them (only tested video). | |
63 | - fixed h263 white bug. | |
64 | - fixed phase rounding in img resample filter. | |
65 | - add mmx code for polyphase img resample filter. | |
66 | - added CPU autodetect. | |
67 | - added generic title/author/copyright/comment string handling (ASF and RM use them). | |
68 | - added SWF demux to extract MP3 track (not usable yet because no MP3 | |
69 | decoder). | |
70 | - added fractional frame rate support. | |
71 | - codecs are no longer searched by read_header() (should fix ffserver | |
72 | segfault). | |
73 | ||
74 | version 0.4.3: | |
75 | ||
76 | - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq@amsat.org>). | |
77 | - fixed raw yuv output. | |
78 | - added motion rounding support in MPEG4. | |
79 | - fixed motion bug rounding in MSMPEG4. | |
80 | - added B frame handling in video core. | |
81 | - added full MPEG1 decoding support. | |
82 | - added partial (frame only) MPEG2 support. | |
83 | - changed the FOURCC code for H.263 to "U263" to be able to see the | |
84 | +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with | |
85 | this +codec ;) (JuanJo). | |
86 | - Halfpel motion estimation after mb type selection (JuanJo). | |
87 | - added pgm and .Y.U.V output format. | |
88 | - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or | |
89 | output. | |
90 | - added pgmpipe I/O format (original patch from Martin Aumueller | |
91 | <lists@reserv.at>, but changed completely since we use a format | |
92 | instead of a protocol). | |
93 | ||
94 | version 0.4.2: | |
95 | ||
96 | - added H263/MPEG4/MSMPEG4 decoding support. MPEG4 decoding support | |
97 | (for openDIVX) is almost complete: 8x8 MVs and rounding are | |
98 | missing. MSMPEG4 support is complete. | |
99 | - added prototype MPEG1 decoder. Only I and P frames handled yet (it | |
100 | can decode ffmpeg mpegs :-)). | |
101 | - added libavcodec API documentation (see apiexample.c). | |
102 | - fixed image polyphase bug (the bottom of some images could be | |
103 | greenish). | |
104 | - added support for non clipped motion vectors (decoding only) | |
105 | and image sizes non multiple of 16. | |
106 | - added support for AC prediction (decoding only). | |
107 | - added file overwrite confirmation (can be disabled with -y). | |
108 | - Added custom size picture to H.263 using H.263+ (Juanjo). | |
109 | ||
110 | version 0.4.1: | |
111 | ||
112 | - added MSMPEG4 (aka DIVX) compatible encoder. Changed default codec | |
113 | of avi and asf to DIV3. | |
114 | - added -me option to set motion estimation method | |
115 | (default=log). suppressed redundant -hq option. | |
116 | - added options -acodec and -vcodec to force a given codec (useful for | |
117 | AVI for example). | |
118 | - fixed -an option. | |
119 | - improved dct_quantize speed. | |
120 | - factorized some motion estimation code. | |
121 | ||
122 | version 0.4.0: | |
123 | ||
124 | - removing grab code from ffserver and moved it to ffmpeg. Added multi | |
125 | stream support to ffmpeg. | |
126 | - added timeshifting support for live feeds (option ?date=xxx in the | |
127 | URL). | |
128 | - added high quality image resize code with polyphase filter (need | |
129 | mmx/see optimisation). Enable multiple image size support in ffserver. | |
130 | - added multi live feed support in ffserver. | |
131 | - suppressed master feature from ffserver (it should be done with an | |
132 | external program which opens the .ffm url and writes it to another | |
133 | ffserver). | |
134 | - added preliminary support for video stream parsing (wav and avi half | |
135 | done). Added proper support for audio/video file convertion in | |
136 | ffmpeg. | |
137 | - added preliminary support for video file sending from ffserver. | |
138 | - redesigning I/O subsystem : now using URL based input and output | |
139 | (see avio.h). | |
140 | - added wav format support. | |
141 | - added "tty user interface" to ffmpeg to stop grabbing gracefully. | |
142 | - added MMX/SSE optimizations to SAD (Sums of Absolutes Diferences) | |
143 | (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo@atmlab.utfsm.cl>). | |
144 | - added MMX DCT from mpeg2_movie 1.5 (Juanjo). | |
145 | - added new motion estimation algorithms, log and phods (Juanjo). | |
146 | - changed directories : libav for format handling, libavcodec for | |
147 | codecs. | |
148 | ||
149 | version 0.3.4: | |
150 | ||
151 | - added stereo in mpeg audio encoder. | |
152 | ||
153 | version 0.3.3: | |
154 | ||
155 | - added 'high quality' mode which use motion vectors. It can be used in | |
156 | real time at low resolution. | |
157 | - fixed rounding problems which caused quality problems at high | |
158 | bitrates and large gop size. | |
159 | ||
160 | version 0.3.2: small fixes | |
161 | ||
162 | - asf fixes | |
163 | - put_seek bug fix | |
164 | ||
165 | version 0.3.1: added avi/divx support | |
166 | ||
167 | - added avi support | |
168 | - added mpeg4 codec compatible with open divx. It is based on the h263 | |
169 | codec. | |
170 | - added sound for flash format (not tested) | |
