804 2009-12-05 - r20734 - lavfi 1.12.0 - avfilter_draw_slice()
805 Add a slice_dir parameter to avfilter_draw_slice().
806
807 2009-11-26 - r20611 - lavfi 1.11.0 - AVFilter
808 Remove the next field from AVFilter, this is not anymore required.
809
810 2009-11-25 - r20607 - lavfi 1.10.0 - avfilter_next()
811 Introduce the avfilter_next() function.
812
813 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
814 Change the signature of avfilter_register() to make it return an
815 int. This is required since now the registration operation may fail.
816
817 2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
818 Make the pixdesc.h API public.
819
820 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next
821 Add a next field to AVFilter, this is used for simplifying the
822 registration and management of the registered filters.
823
824 2009-10-23 - r20356 - lavfi 1.4.1 - AVFilter.description
825 Add a description field to AVFilter.
826
827 2009-10-19 - r20302 - lavfi 1.3.0 - avfilter_make_format_list()
828 Change the interface of avfilter_make_format_list() from
829 avfilter_make_format_list(int n, ...) to

831
832 2009-10-18 - r20272 - lavfi 1.0.0 - avfilter_get_video_buffer()
833 Make avfilter_get_video_buffer() recursive and add the w and h
834 parameters to it.
835
836 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic
837 Add w and h fields to AVFilterPic.
838
839 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
840 This is now an unsigned int instead of a signed int.
841
842 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
843 Add a pts field to AVSubtitle which gives the subtitle packet pts
844 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
845 not work right without this.
846
847 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
848 PKT_FLAG_KEY has been deprecated and will be dropped at the next
849 major version. Use AV_PKT_FLAG_KEY instead.
850
851 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
852 av_lockmgr_register() can be used to register a callback function
853 that lavc (and in the future, libraries that depend on lavc) can use
854 to implement mutexes. The application should provide a callback function
855 that implements the AV_LOCK_* operations described in avcodec.h.
856 When the lock manager is registered, FFmpeg is guaranteed to behave
857 correctly in a multi-threaded application.
858
859 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
860 av_free_packet() is no longer an inline function. It is now exported.
861
862 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
863 Please use NULL instead. This has been supported since r16506
864 (lavf > 52.23.1, lavc > 52.10.0).
865
866 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
867 The old decoding functions are deprecated, all new code should use the
868 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
869 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
870 argument instead of a const uint8_t *buf / int buf_size pair.
871
872 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
873 Introduce the av_fifo_space() function.
874
875 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
876 Move AVPacket declaration from libavformat/avformat.h to
877 libavcodec/avcodec.h.
878
879 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
880 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
881 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
882 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
883 PIX_FMT_BGR32_1 are now macros.
884 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
885 Re-sort the enum PixelFormat list accordingly.
886 This change breaks API/ABI backward compatibility.
887
888 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
889 Add the enum PixelFormat values:
890 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
891 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
892
893 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
894 The Mersenne Twister PRNG implemented through the av_random* functions
895 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
896 instead.
897
898 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
899 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
900 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
901 and av_fifo_realloc2.
902 In addition, the order of the function arguments of av_fifo_generic_read
903 was changed to match av_fifo_generic_write.
904 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
905 applications, they may not use sizeof() or directly access members.
906
907 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
908 Introduce a new metadata API (see av_metadata_get() and friends).
909 The old API is now deprecated and should not be used anymore. This especially
910 includes the following structure fields:
911 - AVFormatContext.title
912 - AVFormatContext.author
913 - AVFormatContext.copyright
914 - AVFormatContext.comment
915 - AVFormatContext.album
916 - AVFormatContext.year
917 - AVFormatContext.track
918 - AVFormatContext.genre
919 - AVStream.language
920 - AVStream.filename
921 - AVProgram.provider_name
922 - AVProgram.name
923 - AVChapter.title
