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