973 For audio formats with fixed frame size, the last frame

1923 Change the function signatures:
1924 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
1925 AVFilterFormats *avfilter_make_format_list(const int *fmts);

1928 int avfilter_add_format (AVFilterFormats **avff, int fmt);
1930 AVFilterFormats *avfilter_all_colorspaces(void); ->
1931 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
1933 This change breaks libavfilter API/ABI.

2122 Introduce the avfilter_next() function.
2124 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2125 Change the signature of avfilter_register() to make it return an
2126 int. This is required since now the registration operation may fail.
2128 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2129 Make the pixdesc.h API public.
2131 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2150 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2151 This is now an unsigned int instead of a signed int.
2153 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2154 Add a pts field to AVSubtitle which gives the subtitle packet pts
2155 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2156 not work right without this.
2158 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2159 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2160 major version. Use AV_PKT_FLAG_KEY instead.
2162 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2163 av_lockmgr_register() can be used to register a callback function
2164 that lavc (and in the future, libraries that depend on lavc) can use
2165 to implement mutexes. The application should provide a callback function
2166 that implements the AV_LOCK_* operations described in avcodec.h.
2167 When the lock manager is registered, FFmpeg is guaranteed to behave
2168 correctly in a multi-threaded application.
2170 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2171 av_free_packet() is no longer an inline function. It is now exported.
2173 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2174 Please use NULL instead. This has been supported since r16506
2175 (lavf > 52.23.1, lavc > 52.10.0).
2177 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2178 The old decoding functions are deprecated, all new code should use the
2179 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2180 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2181 argument instead of a const uint8_t *buf / int buf_size pair.
2183 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2184 Introduce the av_fifo_space() function.
2186 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2187 Move AVPacket declaration from libavformat/avformat.h to
2188 libavcodec/avcodec.h.
2190 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2191 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2192 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2193 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2194 PIX_FMT_BGR32_1 are now macros.
2195 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2196 Re-sort the enum PixelFormat list accordingly.
2197 This change breaks API/ABI backward compatibility.
2199 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2200 Add the enum PixelFormat values:
2201 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2202 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2204 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2205 The Mersenne Twister PRNG implemented through the av_random* functions
2206 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2209 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2210 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2211 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2212 and av_fifo_realloc2.
2213 In addition, the order of the function arguments of av_fifo_generic_read
2214 was changed to match av_fifo_generic_write.
2215 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2216 applications, they may not use sizeof() or directly access members.
2218 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2219 Introduce a new metadata API (see av_metadata_get() and friends).
2220 The old API is now deprecated and should not be used anymore. This especially
2221 includes the following structure fields:
2222 - AVFormatContext.title
2223 - AVFormatContext.author
2224 - AVFormatContext.copyright
2225 - AVFormatContext.comment
2226 - AVFormatContext.album
2227 - AVFormatContext.year
2228 - AVFormatContext.track
2229 - AVFormatContext.genre
2232 - AVProgram.provider_name
