765 Introduce the avfilter_next() function.
767 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
768 Change the signature of avfilter_register() to make it return an

772 Make the pixdesc.h API public.
774 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next

790 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic
791 Add w and h fields to AVFilterPic.
793 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
794 This is now an unsigned int instead of a signed int.
796 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
797 Add a pts field to AVSubtitle which gives the subtitle packet pts
798 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
799 not work right without this.
801 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
802 PKT_FLAG_KEY has been deprecated and will be dropped at the next
803 major version. Use AV_PKT_FLAG_KEY instead.
805 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
806 av_lockmgr_register() can be used to register a callback function
807 that lavc (and in the future, libraries that depend on lavc) can use
808 to implement mutexes. The application should provide a callback function
809 that implements the AV_LOCK_* operations described in avcodec.h.
810 When the lock manager is registered, FFmpeg is guaranteed to behave
811 correctly in a multi-threaded application.
813 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
814 av_free_packet() is no longer an inline function. It is now exported.
816 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
817 Please use NULL instead. This has been supported since r16506
818 (lavf > 52.23.1, lavc > 52.10.0).
820 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
821 The old decoding functions are deprecated, all new code should use the
822 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
823 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
824 argument instead of a const uint8_t *buf / int buf_size pair.
826 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
827 Introduce the av_fifo_space() function.
829 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
830 Move AVPacket declaration from libavformat/avformat.h to
831 libavcodec/avcodec.h.
833 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
834 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
835 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
836 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
837 PIX_FMT_BGR32_1 are now macros.
838 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
839 Re-sort the enum PixelFormat list accordingly.
840 This change breaks API/ABI backward compatibility.
842 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
843 Add the enum PixelFormat values:
844 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
845 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
847 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
848 The Mersenne Twister PRNG implemented through the av_random* functions
849 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
852 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
853 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
854 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
855 and av_fifo_realloc2.
856 In addition, the order of the function arguments of av_fifo_generic_read
857 was changed to match av_fifo_generic_write.
858 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
859 applications, they may not use sizeof() or directly access members.
