630 Introduce the avfilter_next() function.
632 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
633 Change the signature of avfilter_register() to make it return an

636 2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
637 Make the pixdesc.h API public.
639 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next

658 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size

661 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
662 Add a pts field to AVSubtitle which gives the subtitle packet pts
663 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
664 not work right without this.
666 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
667 PKT_FLAG_KEY has been deprecated and will be dropped at the next
668 major version. Use AV_PKT_FLAG_KEY instead.
670 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
671 av_lockmgr_register() can be used to register a callback function
672 that lavc (and in the future, libraries that depend on lavc) can use
673 to implement mutexes. The application should provide a callback function
674 that implements the AV_LOCK_* operations described in avcodec.h.
675 When the lock manager is registered, FFmpeg is guaranteed to behave
676 correctly in a multi-threaded application.
678 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
679 av_free_packet() is no longer an inline function. It is now exported.
681 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
682 Please use NULL instead. This has been supported since r16506
683 (lavf > 52.23.1, lavc > 52.10.0).
685 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
686 The old decoding functions are deprecated, all new code should use the
687 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
688 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
689 argument instead of a const uint8_t *buf / int buf_size pair.
691 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
692 Introduce the av_fifo_space() function.
694 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
695 Move AVPacket declaration from libavformat/avformat.h to
696 libavcodec/avcodec.h.
698 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
699 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
700 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
701 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
702 PIX_FMT_BGR32_1 are now macros.
703 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
704 Re-sort the enum PixelFormat list accordingly.
705 This change breaks API/ABI backward compatibility.
707 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
708 Add the enum PixelFormat values:
709 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
710 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
712 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
713 The Mersenne Twister PRNG implemented through the av_random* functions
714 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
717 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
718 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
719 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
720 and av_fifo_realloc2.
721 In addition, the order of the function arguments of av_fifo_generic_read
722 was changed to match av_fifo_generic_write.
723 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
724 applications, they may not use sizeof() or directly access members.
726 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
727 Introduce a new metadata API (see av_metadata_get() and friends).
728 The old API is now deprecated and should not be used anymore. This especially
729 includes the following structure fields:
730 - AVFormatContext.title
731 - AVFormatContext.author
732 - AVFormatContext.copyright
733 - AVFormatContext.comment
734 - AVFormatContext.album
735 - AVFormatContext.year
736 - AVFormatContext.track
737 - AVFormatContext.genre
740 - AVProgram.provider_name
