  1. Never assume the API of libav* to be stable unless at least 1 month has passed

  2. since the last major version increase.

  3. 

  4. The last version increases were:

  5. libavcodec:  2012-01-27

  6. libavdevice: 2011-04-18

  7. libavfilter: 2011-04-18

  8. libavformat: 2012-01-27

  9. libpostproc: 2011-04-18

  10. libswscale:  2011-06-20

  11. libavutil:   2011-04-18

  12.

  40.           muxers supporting it (av_write_frame makes sure it is called

  41.           only for muxers with this flag).

  42.

  107.       AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count

  1095. 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()

  1096.   av_lockmgr_register() can be used to register a callback function

  1097.   that lavc (and in the future, libraries that depend on lavc) can use

  1098.   to implement mutexes. The application should provide a callback function

  1099.   that implements the AV_LOCK_* operations described in avcodec.h.

  1100.   When the lock manager is registered, FFmpeg is guaranteed to behave

  1101.   correctly in a multi-threaded application.

  1102. 

  1103. 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()

  1108.   (lavf > 52.23.1, lavc > 52.10.0).

  1109. 

  1110. 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle

  1111.   The old decoding functions are deprecated, all new code should use the

  1112.   new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  1113.   avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt

  1114.   argument instead of a const uint8_t *buf / int buf_size pair.

  1115. 

  1116. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()

  1117.   Introduce the av_fifo_space() function.

  1118. 

  1119. 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket

  1120.   Move AVPacket declaration from libavformat/avformat.h to

  1121.   libavcodec/avcodec.h.

  1122. 

  1123. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats

  1124.   Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  1125.   PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.

  1126.   Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and

  1127.   PIX_FMT_BGR32_1 are now macros.

  1128.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  1129.   Re-sort the enum PixelFormat list accordingly.

  1130.   This change breaks API/ABI backward compatibility.

  1131. 

  1132. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  1133.   Add the enum PixelFormat values:

  1134.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  1135.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  1136. 

  1137. 2009-03-21 - r18116 - lavu 50.0.0  - av_random*

  1138.   The Mersenne Twister PRNG implemented through the av_random* functions

  1139.   was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  1140.   instead.

  1141. 

  1142. 2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer

  1143.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  1144.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  1145.   and av_fifo_realloc2.

  1146.   In addition, the order of the function arguments of av_fifo_generic_read

  1147.   was changed to match av_fifo_generic_write.

  1148.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  1149.   applications, they may not use sizeof() or directly access members.

  1150. 

  1151. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

  1152.   Introduce a new metadata API (see av_metadata_get() and friends).

  1153.   The old API is now deprecated and should not be used anymore. This especially

  1154.   includes the following structure fields:

  1155.     - AVFormatContext.title

  1156.     - AVFormatContext.author

  1157.     - AVFormatContext.copyright

  1158.     - AVFormatContext.comment

  1159.     - AVFormatContext.album

  1160.     - AVFormatContext.year

  1161.     - AVFormatContext.track

  1162.     - AVFormatContext.genre

  1163.     - AVStream.language

  1164.     - AVStream.filename

  1165.     - AVProgram.provider_name

  1166.     - AVProgram.name

  1167.     - AVChapter.title
