786 2009-11-25 - r20607 - lavfi 1.10.0 - avfilter_next()
787 Introduce the avfilter_next() function.
788
789 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
790 Change the signature of avfilter_register() to make it return an
791 int. This is required since now the registration operation may fail.
792
793 2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
794 Make the pixdesc.h API public.
795
796 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next
797 Add a next field to AVFilter, this is used for simplifying the
798 registration and management of the registered filters.
799
800 2009-10-23 - r20356 - lavfi 1.4.1 - AVFilter.description
801 Add a description field to AVFilter.
802
803 2009-10-19 - r20302 - lavfi 1.3.0 - avfilter_make_format_list()
804 Change the interface of avfilter_make_format_list() from
805 avfilter_make_format_list(int n, ...) to
806 avfilter_make_format_list(enum PixelFormat *pix_fmts).
807
808 2009-10-18 - r20272 - lavfi 1.0.0 - avfilter_get_video_buffer()
809 Make avfilter_get_video_buffer() recursive and add the w and h
810 parameters to it.
811
812 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic
813 Add w and h fields to AVFilterPic.
814
815 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
816 This is now an unsigned int instead of a signed int.
817
818 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
819 Add a pts field to AVSubtitle which gives the subtitle packet pts
820 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
821 not work right without this.
822
823 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
824 PKT_FLAG_KEY has been deprecated and will be dropped at the next
825 major version. Use AV_PKT_FLAG_KEY instead.
826
827 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
828 av_lockmgr_register() can be used to register a callback function
829 that lavc (and in the future, libraries that depend on lavc) can use
830 to implement mutexes. The application should provide a callback function
831 that implements the AV_LOCK_* operations described in avcodec.h.
832 When the lock manager is registered, FFmpeg is guaranteed to behave
833 correctly in a multi-threaded application.
834
835 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
836 av_free_packet() is no longer an inline function. It is now exported.
837
838 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
839 Please use NULL instead. This has been supported since r16506
840 (lavf > 52.23.1, lavc > 52.10.0).
841
842 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
843 The old decoding functions are deprecated, all new code should use the
844 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
845 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
846 argument instead of a const uint8_t *buf / int buf_size pair.
847
848 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
849 Introduce the av_fifo_space() function.
850
851 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
852 Move AVPacket declaration from libavformat/avformat.h to
853 libavcodec/avcodec.h.
854
855 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
856 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
857 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
858 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
859 PIX_FMT_BGR32_1 are now macros.
860 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
861 Re-sort the enum PixelFormat list accordingly.
862 This change breaks API/ABI backward compatibility.
863
864 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
865 Add the enum PixelFormat values:
866 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
867 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
868
869 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
870 The Mersenne Twister PRNG implemented through the av_random* functions
871 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
872 instead.
873
874 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
875 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
876 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
877 and av_fifo_realloc2.
878 In addition, the order of the function arguments of av_fifo_generic_read
879 was changed to match av_fifo_generic_write.
880 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
881 applications, they may not use sizeof() or directly access members.
882
883 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
884 Introduce a new metadata API (see av_metadata_get() and friends).
885 The old API is now deprecated and should not be used anymore. This especially
886 includes the following structure fields:
887 - AVFormatContext.title
888 - AVFormatContext.author
889 - AVFormatContext.copyright
890 - AVFormatContext.comment
891 - AVFormatContext.album
892 - AVFormatContext.year
893 - AVFormatContext.track
894 - AVFormatContext.genre
895 - AVStream.language
896 - AVStream.filename
897 - AVProgram.provider_name
898 - AVProgram.name
899 - AVChapter.title
