1063 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
1064 Change the signature of avfilter_register() to make it return an
1065 int. This is required since now the registration operation may fail.
1067 2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
1068 Make the pixdesc.h API public.

1092 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
1093 Add a pts field to AVSubtitle which gives the subtitle packet pts
1094 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1095 not work right without this.
1097 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1098 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1099 major version. Use AV_PKT_FLAG_KEY instead.
1101 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
1102 av_lockmgr_register() can be used to register a callback function
1103 that lavc (and in the future, libraries that depend on lavc) can use
1104 to implement mutexes. The application should provide a callback function
1105 that implements the AV_LOCK_* operations described in avcodec.h.
1106 When the lock manager is registered, FFmpeg is guaranteed to behave
1107 correctly in a multi-threaded application.
1109 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
1110 av_free_packet() is no longer an inline function. It is now exported.
1112 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1113 Please use NULL instead. This has been supported since r16506
1114 (lavf > 52.23.1, lavc > 52.10.0).
1116 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1117 The old decoding functions are deprecated, all new code should use the
1118 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1119 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1120 argument instead of a const uint8_t *buf / int buf_size pair.
1122 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
1123 Introduce the av_fifo_space() function.
1125 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
1126 Move AVPacket declaration from libavformat/avformat.h to
1127 libavcodec/avcodec.h.
1129 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
1130 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1131 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1132 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1133 PIX_FMT_BGR32_1 are now macros.
1134 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1135 Re-sort the enum PixelFormat list accordingly.
1136 This change breaks API/ABI backward compatibility.
1138 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1139 Add the enum PixelFormat values:
1140 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1141 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1143 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
1144 The Mersenne Twister PRNG implemented through the av_random* functions
1145 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1148 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
1149 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1150 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1151 and av_fifo_realloc2.
1152 In addition, the order of the function arguments of av_fifo_generic_read
1153 was changed to match av_fifo_generic_write.
1154 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1155 applications, they may not use sizeof() or directly access members.
1157 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
1158 Introduce a new metadata API (see av_metadata_get() and friends).
1159 The old API is now deprecated and should not be used anymore. This especially
1160 includes the following structure fields:
1161 - AVFormatContext.title
1162 - AVFormatContext.author
1163 - AVFormatContext.copyright
1164 - AVFormatContext.comment
1165 - AVFormatContext.album
1166 - AVFormatContext.year
1167 - AVFormatContext.track
1168 - AVFormatContext.genre
1171 - AVProgram.provider_name
