781 Introduce the avfilter_next() function.
783 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
784 Change the signature of avfilter_register() to make it return an

788 Make the pixdesc.h API public.
790 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next

807 Add w and h fields to AVFilterPic.
809 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
810 This is now an unsigned int instead of a signed int.
812 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
813 Add a pts field to AVSubtitle which gives the subtitle packet pts
814 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
815 not work right without this.
817 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
818 PKT_FLAG_KEY has been deprecated and will be dropped at the next
819 major version. Use AV_PKT_FLAG_KEY instead.
821 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
822 av_lockmgr_register() can be used to register a callback function
823 that lavc (and in the future, libraries that depend on lavc) can use
824 to implement mutexes. The application should provide a callback function
825 that implements the AV_LOCK_* operations described in avcodec.h.
826 When the lock manager is registered, FFmpeg is guaranteed to behave
827 correctly in a multi-threaded application.
829 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
830 av_free_packet() is no longer an inline function. It is now exported.
832 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
833 Please use NULL instead. This has been supported since r16506
834 (lavf > 52.23.1, lavc > 52.10.0).
836 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
837 The old decoding functions are deprecated, all new code should use the
838 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
839 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
840 argument instead of a const uint8_t *buf / int buf_size pair.
842 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
843 Introduce the av_fifo_space() function.

847 libavcodec/avcodec.h.
849 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
850 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
851 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
852 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
853 PIX_FMT_BGR32_1 are now macros.
854 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
855 Re-sort the enum PixelFormat list accordingly.
856 This change breaks API/ABI backward compatibility.
858 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
859 Add the enum PixelFormat values:
860 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
861 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
863 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
864 The Mersenne Twister PRNG implemented through the av_random* functions
865 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
868 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
869 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
870 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
871 and av_fifo_realloc2.
872 In addition, the order of the function arguments of av_fifo_generic_read
873 was changed to match av_fifo_generic_write.
874 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
875 applications, they may not use sizeof() or directly access members.
877 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

882 - AVFormatContext.author
883 - AVFormatContext.copyright
884 - AVFormatContext.comment
885 - AVFormatContext.album
886 - AVFormatContext.year
887 - AVFormatContext.track
888 - AVFormatContext.genre
891 - AVProgram.provider_name
