863 2009-10-18 - r20272 - lavfi 1.0.0 - avfilter_get_video_buffer()
864 Make avfilter_get_video_buffer() recursive and add the w and h
867 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic
868 Add w and h fields to AVFilterPic.
870 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
871 This is now an unsigned int instead of a signed int.
873 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
874 Add a pts field to AVSubtitle which gives the subtitle packet pts
875 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
876 not work right without this.
878 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
879 PKT_FLAG_KEY has been deprecated and will be dropped at the next
880 major version. Use AV_PKT_FLAG_KEY instead.
882 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
883 av_lockmgr_register() can be used to register a callback function
884 that lavc (and in the future, libraries that depend on lavc) can use
885 to implement mutexes. The application should provide a callback function
886 that implements the AV_LOCK_* operations described in avcodec.h.
887 When the lock manager is registered, FFmpeg is guaranteed to behave
888 correctly in a multi-threaded application.
890 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
891 av_free_packet() is no longer an inline function. It is now exported.
893 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
894 Please use NULL instead. This has been supported since r16506
895 (lavf > 52.23.1, lavc > 52.10.0).
897 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
898 The old decoding functions are deprecated, all new code should use the
899 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
900 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
901 argument instead of a const uint8_t *buf / int buf_size pair.
903 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
904 Introduce the av_fifo_space() function.
906 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
907 Move AVPacket declaration from libavformat/avformat.h to
908 libavcodec/avcodec.h.
910 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
911 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
912 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
913 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
914 PIX_FMT_BGR32_1 are now macros.
915 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
916 Re-sort the enum PixelFormat list accordingly.
917 This change breaks API/ABI backward compatibility.
919 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
920 Add the enum PixelFormat values:
921 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
922 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
924 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
925 The Mersenne Twister PRNG implemented through the av_random* functions
926 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
929 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
930 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
931 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
932 and av_fifo_realloc2.
933 In addition, the order of the function arguments of av_fifo_generic_read
934 was changed to match av_fifo_generic_write.
935 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
936 applications, they may not use sizeof() or directly access members.
938 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
939 Introduce a new metadata API (see av_metadata_get() and friends).
940 The old API is now deprecated and should not be used anymore. This especially
941 includes the following structure fields:
942 - AVFormatContext.title
943 - AVFormatContext.author
944 - AVFormatContext.copyright
945 - AVFormatContext.comment
946 - AVFormatContext.album
947 - AVFormatContext.year
948 - AVFormatContext.track
949 - AVFormatContext.genre
952 - AVProgram.provider_name
