  584. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  585. PIX_FMT_BGR32_1 are now macros.
  586. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  587. Re-sort the enum PixelFormat list accordingly.
  588. This change breaks API/ABI backward compatibility.
  589. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
  590. Add the enum PixelFormat values:
  591. PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
  592. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  593. 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
  594. The Mersenne Twister PRNG implemented through the av_random* functions
  595. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  596. instead.
  597. 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
  598. av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  599. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  600. and av_fifo_realloc2.
  601. In addition, the order of the function arguments of av_fifo_generic_read
  602. was changed to match av_fifo_generic_write.
  603. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  604. applications, they may not use sizeof() or directly access members.
  605. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
  606. Introduce a new metadata API (see av_metadata_get() and friends).
  607. The old API is now deprecated and should not be used anymore. This especially
  608. includes the following structure fields:
  609. - AVFormatContext.title
  610. - AVFormatContext.author
  611. - AVFormatContext.copyright
  612. - AVFormatContext.comment
  613. - AVFormatContext.album
  614. - AVFormatContext.year
  615. - AVFormatContext.track
  616. - AVFormatContext.genre
  617. - AVStream.language
  618. - AVStream.filename
  619. - AVProgram.provider_name
  620. - AVProgram.name
  621. - AVChapter.title
