Raw Blame History 

  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. libavresample: 2012-04-24

  982.   Make the pixdesc.h API public.

  983. 

  984. 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

  985.   Add a next field to AVFilter, this is used for simplifying the

  986.   registration and management of the registered filters.

  987. 

  988. 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description

  989.   Add a description field to AVFilter.

  990. 

  991. 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()

  992.   Change the interface of avfilter_make_format_list() from

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

  994.   avfilter_make_format_list(enum PixelFormat *pix_fmts).

  995. 

  996. 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()

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

  998.   parameters to it.

  999. 

  1000. 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic

  1001.   Add w and h fields to AVFilterPic.

  1002. 

  1003. 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

  1004.   This is now an unsigned int instead of a signed int.

  1005. 

  1006. 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts

  1007.   Add a pts field to AVSubtitle which gives the subtitle packet pts

  1008.   in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

  1009.   not work right without this.

  1010. 

  1011. 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY

  1012.   PKT_FLAG_KEY has been deprecated and will be dropped at the next

  1013.   major version. Use AV_PKT_FLAG_KEY instead.

  1014. 

  1015. 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()

  1016.   av_lockmgr_register() can be used to register a callback function

  1017.   that lavc (and in the future, libraries that depend on lavc) can use

  1018.   to implement mutexes. The application should provide a callback function

  1019.   that implements the AV_LOCK_* operations described in avcodec.h.

  1020.   When the lock manager is registered, FFmpeg is guaranteed to behave

  1021.   correctly in a multi-threaded application.

  1022. 

  1023. 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()

  1024.   av_free_packet() is no longer an inline function. It is now exported.

  1025. 

  1026. 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()

  1027.   Please use NULL instead. This has been supported since r16506

  1028.   (lavf > 52.23.1, lavc > 52.10.0).

  1029. 

  1030. 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle

  1031.   The old decoding functions are deprecated, all new code should use the

  1032.   new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  1033.   avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt

  1034.   argument instead of a const uint8_t *buf / int buf_size pair.

  1035. 

  1036. 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

  1037.   Introduce the av_fifo_space() function.

  1038. 

  1039. 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket

  1040.   Move AVPacket declaration from libavformat/avformat.h to

  1041.   libavcodec/avcodec.h.

  1042. 

  1043. 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats

  1044.   Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  1045.   PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.

  1046.   Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and

  1047.   PIX_FMT_BGR32_1 are now macros.

  1048.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  1049.   Re-sort the enum PixelFormat list accordingly.

  1050.   This change breaks API/ABI backward compatibility.

  1051. 

  1052. 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  1053.   Add the enum PixelFormat values:

  1054.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  1055.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  1056. 

  1057. 2009-03-21 - ee6624e - lavu 50.0.0  - av_random*

  1058.   The Mersenne Twister PRNG implemented through the av_random* functions

  1059.   was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  1060.   instead.

  1061. 

  1062. 2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer

  1063.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  1064.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  1065.   and av_fifo_realloc2.

  1066.   In addition, the order of the function arguments of av_fifo_generic_read

  1067.   was changed to match av_fifo_generic_write.

  1068.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  1069.   applications, they may not use sizeof() or directly access members.

  1070. 

  1071. 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API

  1072.   Introduce a new metadata API (see av_metadata_get() and friends).

  1073.   The old API is now deprecated and should not be used anymore. This especially

  1074.   includes the following structure fields:

  1075.     - AVFormatContext.title

  1076.     - AVFormatContext.author

  1077.     - AVFormatContext.copyright

  1078.     - AVFormatContext.comment

  1079.     - AVFormatContext.album

  1080.     - AVFormatContext.year

  1081.     - AVFormatContext.track

  1082.     - AVFormatContext.genre

  1083.     - AVStream.language

  1084.     - AVStream.filename

  1085.     - AVProgram.provider_name

  1086.     - AVProgram.name

  1087.     - AVChapter.title
