775 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
776 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
777 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
778 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
779 PIX_FMT_BGR32_1 are now macros.
780 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
781 Re-sort the enum PixelFormat list accordingly.
782 This change breaks API/ABI backward compatibility.
783
784 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
785 Add the enum PixelFormat values:
786 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
787 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

789 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
790 The Mersenne Twister PRNG implemented through the av_random* functions
791 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
792 instead.
793
794 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
795 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
796 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
797 and av_fifo_realloc2.
798 In addition, the order of the function arguments of av_fifo_generic_read
799 was changed to match av_fifo_generic_write.
800 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
801 applications, they may not use sizeof() or directly access members.
802
803 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
804 Introduce a new metadata API (see av_metadata_get() and friends).
805 The old API is now deprecated and should not be used anymore. This especially
806 includes the following structure fields:
807 - AVFormatContext.title
808 - AVFormatContext.author
809 - AVFormatContext.copyright
810 - AVFormatContext.comment
811 - AVFormatContext.album
812 - AVFormatContext.year
813 - AVFormatContext.track
814 - AVFormatContext.genre
815 - AVStream.language
816 - AVStream.filename
817 - AVProgram.provider_name
818 - AVProgram.name
819 - AVChapter.title
