  556.   new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  557.   avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt

  558.   argument instead of a const uint8_t *buf / int buf_size pair.

  559. 

  560. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()

  568.   Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  569.   PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.

  570.   Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and

  571.   PIX_FMT_BGR32_1 are now macros.

  572.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  573.   Re-sort the enum PixelFormat list accordingly.

  574.   This change breaks API/ABI backward compatibility.

  575.

  577.   Add the enum PixelFormat values:

  578.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  579.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  588.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  589.   and av_fifo_realloc2.

  590.   In addition, the order of the function arguments of av_fifo_generic_read

  591.   was changed to match av_fifo_generic_write.

  592.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  593.   applications, they may not use sizeof() or directly access members.

  594. 

  595. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

  596.   Introduce a new metadata API (see av_metadata_get() and friends).
