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

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

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

  983.   correctly in a multi-threaded application.

  984. 

  985. 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()

  986.   av_free_packet() is no longer an inline function. It is now exported.

  987. 

  988. 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()

  989.   Please use NULL instead. This has been supported since r16506

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

  991. 

  992. 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle

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

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

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

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

  997. 

  998. 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

  999.   Introduce the av_fifo_space() function.

  1000. 

  1001. 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket

  1002.   Move AVPacket declaration from libavformat/avformat.h to

  1003.   libavcodec/avcodec.h.

  1004. 

  1005. 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats

  1006.   Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  1007.   PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.

  1008.   Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and

  1009.   PIX_FMT_BGR32_1 are now macros.

  1010.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  1011.   Re-sort the enum PixelFormat list accordingly.

  1012.   This change breaks API/ABI backward compatibility.

  1013. 

  1014. 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  1015.   Add the enum PixelFormat values:

  1016.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  1017.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  1018. 

  1019. 2009-03-21 - ee6624e - lavu 50.0.0  - av_random*

  1020.   The Mersenne Twister PRNG implemented through the av_random* functions

  1021.   was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  1022.   instead.

  1023. 

  1024. 2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer

  1025.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  1026.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  1027.   and av_fifo_realloc2.

  1028.   In addition, the order of the function arguments of av_fifo_generic_read

  1029.   was changed to match av_fifo_generic_write.

  1030.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  1031.   applications, they may not use sizeof() or directly access members.

  1032. 

  1033. 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API

  1034.   Introduce a new metadata API (see av_metadata_get() and friends).

  1035.   The old API is now deprecated and should not be used anymore. This especially

  1036.   includes the following structure fields:

  1037.     - AVFormatContext.title

  1038.     - AVFormatContext.author

  1039.     - AVFormatContext.copyright

  1040.     - AVFormatContext.comment

  1041.     - AVFormatContext.album

  1042.     - AVFormatContext.year

  1043.     - AVFormatContext.track

  1044.     - AVFormatContext.genre

  1045.     - AVStream.language

  1046.     - AVStream.filename

  1047.     - AVProgram.provider_name

  1048.     - AVProgram.name

  1049.     - AVChapter.title
