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

  676. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  677. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  678. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  679. PIX_FMT_BGR32_1 are now macros.
  680. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  681. Re-sort the enum PixelFormat list accordingly.
  682. This change breaks API/ABI backward compatibility.
  683. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  695. In addition, the order of the function arguments of av_fifo_generic_read
  696. was changed to match av_fifo_generic_write.
  697. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  698. applications, they may not use sizeof() or directly access members.
  699. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
  700. Introduce a new metadata API (see av_metadata_get() and friends).
  701. The old API is now deprecated and should not be used anymore. This especially
  702. includes the following structure fields:
