809 Add a slice_dir parameter to avfilter_draw_slice().
810

815 Introduce the avfilter_next() function.
816
817 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
818 Change the signature of avfilter_register() to make it return an
819 int. This is required since now the registration operation may fail.
820
821 2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
822 Make the pixdesc.h API public.
823
824 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next
825 Add a next field to AVFilter, this is used for simplifying the
826 registration and management of the registered filters.
827
828 2009-10-23 - r20356 - lavfi 1.4.1 - AVFilter.description
829 Add a description field to AVFilter.

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