778 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
779 The old decoding functions are deprecated, all new code should use the
780 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
781 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
782 argument instead of a const uint8_t *buf / int buf_size pair.
783
784 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
785 Introduce the av_fifo_space() function.
786
787 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
788 Move AVPacket declaration from libavformat/avformat.h to
789 libavcodec/avcodec.h.
790
791 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
792 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
793 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
794 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
795 PIX_FMT_BGR32_1 are now macros.
796 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
797 Re-sort the enum PixelFormat list accordingly.
798 This change breaks API/ABI backward compatibility.
799
800 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
801 Add the enum PixelFormat values:
802 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
803 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
804
805 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
806 The Mersenne Twister PRNG implemented through the av_random* functions
807 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
808 instead.
809
810 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
811 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
812 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
813 and av_fifo_realloc2.
814 In addition, the order of the function arguments of av_fifo_generic_read
815 was changed to match av_fifo_generic_write.
816 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
817 applications, they may not use sizeof() or directly access members.
818
819 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
820 Introduce a new metadata API (see av_metadata_get() and friends).
821 The old API is now deprecated and should not be used anymore. This especially
822 includes the following structure fields:
823 - AVFormatContext.title
824 - AVFormatContext.author
825 - AVFormatContext.copyright
826 - AVFormatContext.comment
827 - AVFormatContext.album
828 - AVFormatContext.year
829 - AVFormatContext.track
830 - AVFormatContext.genre
831 - AVStream.language
832 - AVStream.filename
833 - AVProgram.provider_name
834 - AVProgram.name
835 - AVChapter.title
