  874. new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  875. avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  876. argument instead of a const uint8_t *buf / int buf_size pair.
  877. 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
  878. Introduce the av_fifo_space() function.
  879. 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
  880. Move AVPacket declaration from libavformat/avformat.h to
  881. libavcodec/avcodec.h.
  882. 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
  883. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  884. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  885. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  886. PIX_FMT_BGR32_1 are now macros.
  887. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  888. Re-sort the enum PixelFormat list accordingly.
  889. This change breaks API/ABI backward compatibility.
  890. 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
  891. Add the enum PixelFormat values:
  892. PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
  893. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  894. 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
  895. The Mersenne Twister PRNG implemented through the av_random* functions
  896. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  897. instead.
  898. 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
  899. av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  900. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  901. and av_fifo_realloc2.
  902. In addition, the order of the function arguments of av_fifo_generic_read
  903. was changed to match av_fifo_generic_write.
  904. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  905. applications, they may not use sizeof() or directly access members.
  906. 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
  907. Introduce a new metadata API (see av_metadata_get() and friends).
  908. The old API is now deprecated and should not be used anymore. This especially
  909. includes the following structure fields:
  910. - AVFormatContext.title
  911. - AVFormatContext.author
  912. - AVFormatContext.copyright
  913. - AVFormatContext.comment
  914. - AVFormatContext.album
  915. - AVFormatContext.year
  916. - AVFormatContext.track
  917. - AVFormatContext.genre
  918. - AVStream.language
  919. - AVStream.filename
  920. - AVProgram.provider_name
  921. - AVProgram.name
  922. - AVChapter.title
