616 Introduce the avfilter_next() function.
618 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
619 Change the signature of avfilter_register() to make it return an
620 int. This is required since now the registration operation may fail.
622 2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
623 Make the pixdesc.h API public.
625 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next

644 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
645 This is now an unsigned int instead of a signed int.
647 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
648 Add a pts field to AVSubtitle which gives the subtitle packet pts
649 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
650 not work right without this.
652 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
653 PKT_FLAG_KEY has been deprecated and will be dropped at the next
654 major version. Use AV_PKT_FLAG_KEY instead.
656 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
657 av_lockmgr_register() can be used to register a callback function
658 that lavc (and in the future, libraries that depend on lavc) can use
659 to implement mutexes. The application should provide a callback function
660 that implements the AV_LOCK_* operations described in avcodec.h.
661 When the lock manager is registered, FFmpeg is guaranteed to behave
662 correctly in a multi-threaded application.
664 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
665 av_free_packet() is no longer an inline function. It is now exported.
667 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
668 Please use NULL instead. This has been supported since r16506
669 (lavf > 52.23.1, lavc > 52.10.0).
671 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
672 The old decoding functions are deprecated, all new code should use the
673 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
674 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
675 argument instead of a const uint8_t *buf / int buf_size pair.
677 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
678 Introduce the av_fifo_space() function.
680 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
681 Move AVPacket declaration from libavformat/avformat.h to
682 libavcodec/avcodec.h.
684 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
685 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
686 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
687 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
688 PIX_FMT_BGR32_1 are now macros.
689 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
690 Re-sort the enum PixelFormat list accordingly.
691 This change breaks API/ABI backward compatibility.
693 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
694 Add the enum PixelFormat values:
695 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
696 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
698 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
699 The Mersenne Twister PRNG implemented through the av_random* functions
700 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
703 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
704 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
705 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
706 and av_fifo_realloc2.
707 In addition, the order of the function arguments of av_fifo_generic_read
708 was changed to match av_fifo_generic_write.
709 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
710 applications, they may not use sizeof() or directly access members.
712 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
713 Introduce a new metadata API (see av_metadata_get() and friends).
714 The old API is now deprecated and should not be used anymore. This especially
715 includes the following structure fields:
716 - AVFormatContext.title
717 - AVFormatContext.author
718 - AVFormatContext.copyright
719 - AVFormatContext.comment
720 - AVFormatContext.album
721 - AVFormatContext.year
722 - AVFormatContext.track
723 - AVFormatContext.genre
726 - AVProgram.provider_name
