2 since the last major version increase.
4 The last version increases were:

1068 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1069 Change the signature of avfilter_register() to make it return an
1070 int. This is required since now the registration operation may fail.

1097 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1098 Add a pts field to AVSubtitle which gives the subtitle packet pts
1099 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

1102 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1103 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1104 major version. Use AV_PKT_FLAG_KEY instead.
1106 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1107 av_lockmgr_register() can be used to register a callback function
1108 that lavc (and in the future, libraries that depend on lavc) can use
1109 to implement mutexes. The application should provide a callback function
1110 that implements the AV_LOCK_* operations described in avcodec.h.
1111 When the lock manager is registered, FFmpeg is guaranteed to behave
1112 correctly in a multi-threaded application.
1114 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1115 av_free_packet() is no longer an inline function. It is now exported.
1117 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1118 Please use NULL instead. This has been supported since r16506
1119 (lavf > 52.23.1, lavc > 52.10.0).
1121 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1122 The old decoding functions are deprecated, all new code should use the
1123 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1124 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1125 argument instead of a const uint8_t *buf / int buf_size pair.
1127 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1128 Introduce the av_fifo_space() function.
1130 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1131 Move AVPacket declaration from libavformat/avformat.h to
1132 libavcodec/avcodec.h.
1134 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1135 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1136 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1137 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1138 PIX_FMT_BGR32_1 are now macros.
1139 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1140 Re-sort the enum PixelFormat list accordingly.
1141 This change breaks API/ABI backward compatibility.
1143 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1144 Add the enum PixelFormat values:
1145 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1146 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1148 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1149 The Mersenne Twister PRNG implemented through the av_random* functions
1150 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1153 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1154 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1155 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1156 and av_fifo_realloc2.
1157 In addition, the order of the function arguments of av_fifo_generic_read
1158 was changed to match av_fifo_generic_write.
1159 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1160 applications, they may not use sizeof() or directly access members.
1162 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1163 Introduce a new metadata API (see av_metadata_get() and friends).
1164 The old API is now deprecated and should not be used anymore. This especially
1165 includes the following structure fields:
1166 - AVFormatContext.title
1167 - AVFormatContext.author
1168 - AVFormatContext.copyright
1169 - AVFormatContext.comment
1170 - AVFormatContext.album
1171 - AVFormatContext.year
1172 - AVFormatContext.track
1173 - AVFormatContext.genre
1176 - AVProgram.provider_name
