  982. 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()

  983.   Change the interface of avfilter_make_format_list() from

  984.   avfilter_make_format_list(int n, ...) to

  985.   avfilter_make_format_list(enum PixelFormat *pix_fmts).

  986. 

  987. 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()

  988.   Make avfilter_get_video_buffer() recursive and add the w and h

  989.   parameters to it.

  990. 

  991. 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic

  992.   Add w and h fields to AVFilterPic.

  993. 

  994. 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

  995.   This is now an unsigned int instead of a signed int.

  996. 

  997. 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts

  998.   Add a pts field to AVSubtitle which gives the subtitle packet pts

  999.   in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

  1000.   not work right without this.

  1001. 

  1002. 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY

  1003.   PKT_FLAG_KEY has been deprecated and will be dropped at the next

  1004.   major version. Use AV_PKT_FLAG_KEY instead.

  1005. 

  1006. 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()

  1007.   av_lockmgr_register() can be used to register a callback function

  1008.   that lavc (and in the future, libraries that depend on lavc) can use

  1009.   to implement mutexes. The application should provide a callback function

  1010.   that implements the AV_LOCK_* operations described in avcodec.h.

  1011.   When the lock manager is registered, FFmpeg is guaranteed to behave

  1012.   correctly in a multi-threaded application.

  1013. 

  1014. 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()

  1015.   av_free_packet() is no longer an inline function. It is now exported.

  1016. 

  1017. 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()

  1018.   Please use NULL instead. This has been supported since r16506

  1019.   (lavf > 52.23.1, lavc > 52.10.0).

  1020. 

  1021. 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle

  1022.   The old decoding functions are deprecated, all new code should use the

  1023.   new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  1024.   avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt

  1025.   argument instead of a const uint8_t *buf / int buf_size pair.

  1026. 

  1027. 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

  1028.   Introduce the av_fifo_space() function.

  1029. 

  1030. 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket

  1031.   Move AVPacket declaration from libavformat/avformat.h to

  1032.   libavcodec/avcodec.h.

  1033. 

  1034. 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats

  1035.   Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  1036.   PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.

  1037.   Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and

  1038.   PIX_FMT_BGR32_1 are now macros.

  1039.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  1040.   Re-sort the enum PixelFormat list accordingly.

  1041.   This change breaks API/ABI backward compatibility.

  1042. 

  1043. 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  1044.   Add the enum PixelFormat values:

  1045.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  1046.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  1047. 

  1048. 2009-03-21 - ee6624e - lavu 50.0.0  - av_random*

  1049.   The Mersenne Twister PRNG implemented through the av_random* functions

  1050.   was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  1051.   instead.

  1052. 

  1053. 2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer

  1054.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  1055.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  1056.   and av_fifo_realloc2.

  1057.   In addition, the order of the function arguments of av_fifo_generic_read

  1058.   was changed to match av_fifo_generic_write.

  1059.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  1060.   applications, they may not use sizeof() or directly access members.

  1061. 

  1062. 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API

  1063.   Introduce a new metadata API (see av_metadata_get() and friends).

  1064.   The old API is now deprecated and should not be used anymore. This especially

  1065.   includes the following structure fields:

  1066.     - AVFormatContext.title

  1067.     - AVFormatContext.author

  1068.     - AVFormatContext.copyright

  1069.     - AVFormatContext.comment

  1070.     - AVFormatContext.album

  1071.     - AVFormatContext.year

  1072.     - AVFormatContext.track

  1073.     - AVFormatContext.genre

  1074.     - AVStream.language

  1075.     - AVStream.filename

  1076.     - AVProgram.provider_name

  1077.     - AVProgram.name

  1078.     - AVChapter.title
