889 Add a type field to AVFilterLink.
891 Change the field types:
892 enum PixelFormat format -> int format in AVFilterBuffer
893 enum PixelFormat *formats -> int *formats in AVFilterFormats
894 enum PixelFormat *format -> int format in AVFilterLink
896 Change the function signatures:
897 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
898 AVFilterFormats *avfilter_make_format_list(const int *fmts);
900 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
901 int avfilter_add_format (AVFilterFormats **avff, int fmt);
903 AVFilterFormats *avfilter_all_colorspaces(void); ->
904 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
906 This change breaks libavfilter API/ABI.

1089 2009-12-05 - r20734 - lavfi 1.12.0 - avfilter_draw_slice()
1090 Add a slice_dir parameter to avfilter_draw_slice().
1092 2009-11-26 - r20611 - lavfi 1.11.0 - AVFilter
1093 Remove the next field from AVFilter, this is not anymore required.
1095 2009-11-25 - r20607 - lavfi 1.10.0 - avfilter_next()
1096 Introduce the avfilter_next() function.
1098 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
1099 Change the signature of avfilter_register() to make it return an
1100 int. This is required since now the registration operation may fail.
1102 2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
1103 Make the pixdesc.h API public.
1105 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next
1106 Add a next field to AVFilter, this is used for simplifying the
1107 registration and management of the registered filters.
1109 2009-10-23 - r20356 - lavfi 1.4.1 - AVFilter.description
1110 Add a description field to AVFilter.
1112 2009-10-19 - r20302 - lavfi 1.3.0 - avfilter_make_format_list()

1117 2009-10-18 - r20272 - lavfi 1.0.0 - avfilter_get_video_buffer()
1118 Make avfilter_get_video_buffer() recursive and add the w and h
1121 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic
1122 Add w and h fields to AVFilterPic.
1124 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
1125 This is now an unsigned int instead of a signed int.
1127 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
1128 Add a pts field to AVSubtitle which gives the subtitle packet pts
1129 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1130 not work right without this.
1132 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1133 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1134 major version. Use AV_PKT_FLAG_KEY instead.
1136 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
1137 av_lockmgr_register() can be used to register a callback function
1138 that lavc (and in the future, libraries that depend on lavc) can use
1139 to implement mutexes. The application should provide a callback function
1140 that implements the AV_LOCK_* operations described in avcodec.h.
1141 When the lock manager is registered, FFmpeg is guaranteed to behave
1142 correctly in a multi-threaded application.
1144 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
1145 av_free_packet() is no longer an inline function. It is now exported.
1147 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1148 Please use NULL instead. This has been supported since r16506
1149 (lavf > 52.23.1, lavc > 52.10.0).
1151 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1152 The old decoding functions are deprecated, all new code should use the
1153 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1154 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1155 argument instead of a const uint8_t *buf / int buf_size pair.
1157 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
1158 Introduce the av_fifo_space() function.
1160 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
1161 Move AVPacket declaration from libavformat/avformat.h to
1162 libavcodec/avcodec.h.
1164 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
1165 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1166 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1167 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1168 PIX_FMT_BGR32_1 are now macros.
1169 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1170 Re-sort the enum PixelFormat list accordingly.
1171 This change breaks API/ABI backward compatibility.
1173 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1174 Add the enum PixelFormat values:
1175 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1176 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1178 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
1179 The Mersenne Twister PRNG implemented through the av_random* functions
1180 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1183 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
1184 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1185 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1186 and av_fifo_realloc2.
1187 In addition, the order of the function arguments of av_fifo_generic_read
1188 was changed to match av_fifo_generic_write.
1189 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1190 applications, they may not use sizeof() or directly access members.
1192 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
1193 Introduce a new metadata API (see av_metadata_get() and friends).
1194 The old API is now deprecated and should not be used anymore. This especially
1195 includes the following structure fields:
1196 - AVFormatContext.title
1197 - AVFormatContext.author
1198 - AVFormatContext.copyright
1199 - AVFormatContext.comment
1200 - AVFormatContext.album
1201 - AVFormatContext.year
1202 - AVFormatContext.track
1203 - AVFormatContext.genre
1206 - AVProgram.provider_name
