268 e1d9dbf Add a new installed header - buffersrc.h
269 It contains a new function av_buffersrc_buffer() that allows passing
270 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
271 it allows for direct rendering.
272 1c9e340 Add avfilter_copy_frame_props() for copying properties from

1108 Remove the next field from AVFilter, this is not anymore required.
1110 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1111 Introduce the avfilter_next() function.
1113 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1114 Change the signature of avfilter_register() to make it return an
1115 int. This is required since now the registration operation may fail.
1117 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1118 Make the pixdesc.h API public.
1120 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1121 Add a next field to AVFilter, this is used for simplifying the

1125 Add a description field to AVFilter.
1127 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1128 Change the interface of avfilter_make_format_list() from

1137 Add w and h fields to AVFilterPic.
1139 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1140 This is now an unsigned int instead of a signed int.
1142 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1143 Add a pts field to AVSubtitle which gives the subtitle packet pts
1144 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1145 not work right without this.
1147 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1148 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1149 major version. Use AV_PKT_FLAG_KEY instead.
1151 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1152 av_lockmgr_register() can be used to register a callback function
1153 that lavc (and in the future, libraries that depend on lavc) can use
1154 to implement mutexes. The application should provide a callback function
1155 that implements the AV_LOCK_* operations described in avcodec.h.
1156 When the lock manager is registered, FFmpeg is guaranteed to behave
1157 correctly in a multi-threaded application.
1159 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1160 av_free_packet() is no longer an inline function. It is now exported.
1162 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1163 Please use NULL instead. This has been supported since r16506
1164 (lavf > 52.23.1, lavc > 52.10.0).
1166 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1167 The old decoding functions are deprecated, all new code should use the
1168 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1169 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1170 argument instead of a const uint8_t *buf / int buf_size pair.
1172 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1173 Introduce the av_fifo_space() function.
1175 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1176 Move AVPacket declaration from libavformat/avformat.h to
1177 libavcodec/avcodec.h.
1179 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1180 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1181 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1182 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1183 PIX_FMT_BGR32_1 are now macros.
1184 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1185 Re-sort the enum PixelFormat list accordingly.
1186 This change breaks API/ABI backward compatibility.
1188 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1189 Add the enum PixelFormat values:
1190 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1191 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1193 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1194 The Mersenne Twister PRNG implemented through the av_random* functions
1195 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1198 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1199 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1200 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1201 and av_fifo_realloc2.
1202 In addition, the order of the function arguments of av_fifo_generic_read
1203 was changed to match av_fifo_generic_write.
1204 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1205 applications, they may not use sizeof() or directly access members.
1207 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1208 Introduce a new metadata API (see av_metadata_get() and friends).
1209 The old API is now deprecated and should not be used anymore. This especially
1210 includes the following structure fields:
1211 - AVFormatContext.title
1212 - AVFormatContext.author
1213 - AVFormatContext.copyright
1214 - AVFormatContext.comment
1215 - AVFormatContext.album
1216 - AVFormatContext.year
1217 - AVFormatContext.track
1218 - AVFormatContext.genre
1221 - AVProgram.provider_name
